These licht weight, large size blocks will safely withstand temperatures up tu 1900F with negligible shrinkace. They are widely used for equipment operating at high temper layer because of its neater insulating value (Superex Combination). Superox M is a diatomaceous earth block having all of the desirable prop erties of Superex, but with a tempera ture limit of 1500F. The lower tem perature limit makes possible a reduc tion in density and conductivity. atures. such as boiler furnaces, hot blast stoves, mains and bustle pipes, petroleum cracking furnaces, pro ducer gas mains and metallurgical furnaces of various types.

THERMOBESTOS* BLOCKS For service to 1200F J-M Thermobestos is made from hydrous calcium silicate combined with asbestos fibers by a special steam process. The result is a com pletely inorganic insulating material which, because of its light weight, low thermal conductivity, great structural strength and in solubility in water, is ideal for high temperature process equipment which must withstand the rigors of severe outdoor operating conditions. Especially recommended for use on outdoor process equipment operat ing at sen ice temperatures up to 1200F, Thermobestos is light enough for easy handling and fast application. Repeated wettings have no permanent effect on it. Its hard composition resists crushing and will w ithstand unusual service abuse. Because it will not bum or carry flame, it is ideal for use in the presence of inflamable gases and liquids.

J-M Rock Cork now offers still another characteristic: incombustibility. It successfully passes, with the highest--"incombustible"-- rating, the Columbia Fire Test as defined by the Na tional Bureau of Standards. Rock Cork sheets and lagging are manufactured from mineral wool combined in production with an asphaltic hinder, molded into sheet or lagging form and baked. Its asphaltic binder furnishes an ideal base for an asphaltic adhesive or finish, assuring an air- and moisture-resistant seal. This strong, long-lasting refrigeration insulating material safeguards even the most sensitive food products because it is free from offensive odors. Its low thermal conductivity provides precise temperature control. Light and readily handled. Rock Cork sheets are furnished in Luce sizes for quick, easy economical application. Standard sizes and properties are given below. Rock Cork in pipe insulation form is described on page 13. Moiiture*reiistont Reek Cork Sheets provide top-volue insulation for all types of refrigeration service. ZEROLITE SHEETS AND LAGGING For Sorvieo to minus 3OOF FOR USE IN THE OIL AND CHEMICAL INDUSTRIES IMMUNE TO MANY ORGANIC SOLVENTS FIRE-RESISTANT Zerolite is a resin-bonded, mineral wool insulating mate rial particularly applicable in the oil and chemical indus tries because of its strength, fire-resistance, low heat conductivity, excellent resistance to moisture, and imminutv to attack or damage by organic solvents such as benzol, methyl ethyl ketone and petroleum fractions and derivatives. Its exceptional moisture-resistance is a result of a special Johns-Manville process which disperses the resin binder over the mineral wool fibers.

All pipes IK in. and smaller, at temperatures above 600F, should be insulated with a single layer of Superex sectional pipe insulation. Small fittings are insulated with J-M No. 352 Insulating Cement or No. 301 Ce ment. For sizes over IK in. at temperatures above 600F, Su perex Combination Insulation should be used. This con sists of a layer of Superex next to pipe with an outer layer of 85S Magnesia.

FINISHES FOR PIPE INSULATION All insulation on indoor piping should be finished with b-oz. canvas pasted or cemented over a layer of 40-Ib. rosin-sized paper; or, where initial cost is a factor, 6-oz. canvas pasted or cemented directly over the standard can vas furnished with the insulation. On fittings, etc., the canvas shall be pasted or cemented directly over the smoothing coat of asbestos cement. The best weather protection for insulated outdoor pipe lines is a weatherproof J-M Double Coated Flexstone jacket of asphalt-saturated and coated asbestos felt. This jacket is secured by loops of No. 16 AWG Copperweld wire applied on 4" maximum centers or K" x 0.015" cor rosion-resistant metal bands and clips on 6" maximum centers, with one loop on each end lap. Double-Coated Flexstone jackets are supplied in rolls 36 in. wide, each roll containing 108 sq. ft. and weighing 50 lbs. Where a flame-retardant weatherproof jacket is required, a J-M Asbestos Firetard* jacket should be used. Firetard is a lamination of heavy asphalt-saturated asbestos felt and plain asbestos felt. It will not carry flame or support combustion. Supplied in rolls 32 in. wide, each roj^ con taining 108 sq. it. and weighing approximately 55 lbs. UALITY PRODUCT s JOHNS.MANVILLE SHEET AND BLOCK INSULATION for hEa Asbesfo-Spong# Felted Blocks Asbesto-Sponge Felfed Sheets and Blocks (For Temperatures to 700' F.) Unusual insulating efficiency, high salvage value and the ab:::-y withstand vibration, shock and rough usage make Asbesto-Spor.ee Ft the ideal material where maximum insulating value and durability a desired. Built up of felts composed of asbestos fibre and small particivspongy cellular material, the remarkable efficiency of Asbesto-Spor Felted is due to the great amount of entrapped dead air and the rr.j surfaces interposed in the path of heat flow. The tightly laminated cc struction of tough asbestos felts is responsible for its immunity to : effects of vibration and rough handling, its sustained high ,r..-ulat:t effectiveness in service, and its unusually high salvage value. Like J-M 85% Magnesia, it is often used outside a layer of Super; for insulating high temperature equipment. Asbesto-Sponge Felted is furnished in sheets 24 x 36 in. and bloc* 6 x 36 in., from 4 to 4 in. thick. Weight approximately 2'; lb.-, per ft. per inch thick. Also furnished in the form of sectional pipe insula:.c (see page 9). Superex Blocks (For Temperaturn to 1900 F.) The most generally adaptable material for application where the insulation must resist temperatures between 600* and 1900 F. is Superex block insulation, made of specially selected and calcined diatomaceous silica, blended and bonded with asbestos fibre, producing an insulation in which are combined the essential qualities of high heat resistance and exceptional insulating value. It has a low thermal conductivity, will safely withstand temperatures up to 1900 F. with negligible shrinkage, and, although relatively light in weight, possesses ample strength for all purposes for which it is recommended. Superex Blocks are widely used for the insulation of boile furnaces, hot blast stoves, open-hearth regenerators, gias tank regenerators, rotary cement kilns, brick kilns, metal lurgical furnaces of various types, producer gas main.-, pctro leum cracking furnaces and other industrial equipment oper ated at high temperatures. Superex Blocks are furnished in standard sizes 3 x IS in.. 6 x 36 in. and 12 x 36 in., flat and curved, from 1 to 4 in thick. Other sizes on special order. Weight approximately 1.9 lbs. per sq. ft. per inch thick. Also furnished in the form of sectional pipe insulation (see page 10). Superex Combination Insulation For service temperatures higher than 600* or 700 F.t one or more layers of J-M 85% Magnesia or Asbesto-Sponge Felted are often used outside of an inner layer of Sup*-rex. this construction being known as Superex Combination Inf lation. This combination results in greater insulating effi ciency and heat resistance for a given insulation thickne-s. The Superex is always used next to the hot surface as a pro tection for the 85% Magnesia or Asbesto-Sponge Felted, which, though high in insulating value, would not. If used alone, withstand the temperature involved. Superex Block end SiLO-Cel C-22 Brick in e Hot Blest Stove in this cate. C-22 Brick wet used neat to the refraetpry. followed by Superet Blocks.

However, the proper thieloiesses of J-M Block Insulation recommended is dependent not alone on the temperatures in volved, but also to a considerable extent on the kind of fuel and its cost and the degree of temperature control required. Application over furnace brickwork adds still another factor --the type and thickness of refractory--which must be con sidered. Typical applications of Superex and Superex Combination Insulation on industrial equipment are shown on subsequent pages. Detailed recommendations applying to any specific insulation problem will be gladly furnished on application to any Johns-Manviux office. Banroc Blankets (For Temperatures to 1000 F.) Banroc Blankets are made of Banroc (rock wool) felted between various fabrics, usually metal, such as galvanized wire netting, copper-bearing metal lath, and rib lath.

The basic material c* which all Sil-O-Cel Brick are comoosed is aimost oure silica (SiO.) which accounts for tneir unusual resistance to high tem peratures behind refractory linings and the fact that Sil-O-Cel C-22 Brick may De used so effec tively as a come nation insulation and refractory witnout fire brick crotection.

Sil-O-Cel Natural Brick (For Tamparaturas to 1600s F.) Sil-O-Cel Natural Brick are cut from the pure mineral Cehte. T are used as an insulation behind refractory linings in high temperatu industrial equipment; and will serve indefinitely at temperature.- up tv 1600* F. without loss of effectiveness. Sil-O-Cel Natural Brick is the most efficient insulating brick outa.: able and is used in preference to other types of Sil-O-Cel brick exetpwhere very severe temperatures are encountered. Sil-O-Cel C-22 Brick (For Tamparaturas to 2000 '' F.) Sil-O-Cel C-22 Brick are highly efficient insulating-refractory brick, calcined for direct exposure to furnace temperatures. They are recon mended up to 2000* F. as a refractory lining to replace fire brick :r. oil and gas-fired furnaces, electric furnaces of the resistance type, anu coal-fired furnaces where they will not be subject to mechanical abra sion or slag action. When used as a refractory, they should be bonuej with C-22 Cement. This material makes possible thinner furnace walls, improved effi ciency and lower operating costs- It combines all of the characteristic; essential to a highly efficient insulating-refractory, including hea: re sistance, exceptional insulating qualities, low heat absorption, unusu ally high compressive strength and ample load-bearing capacity under heat. This combining of the refractory and insulating course not oniv re sults in a saving in construction costs, but also cuts down the heat storage capacity of the masonry. C-22 Brick have a heat capacity less than 1/3 that of fire brick, which effects a highly important economy in intermittent furnace.. Less heat is wasted when the furnace is shut down and the furnace can be brought up to temperature again in a very short time with m:r..mum expense for heat. In preventing transmitted heat loss, C-22 Brio; are three to four times as effective as fire brick. Where furnace temperatures are above 2000* F., or surface ero- on is severe, Sil-O-Cel C-22 Brick, protected by firebrick, are u.-v,! a- m-ulation where the temperature on the insulation will not exceeu j' >" F. Sil-O-Cel Super Briek (For Temperatures to 2500s F.J Sil-O-Cel Super Brick (U. S. Patent No. 1,544,433) is a calcine! type of Sil-O-Cel brick designed for exceptionally severe insulating -ervicn where subjected to temperatures behind the refractory in e\ce-- of 2000* F., and can be used in this manner for temperature.- up to 2500* F. In high temperature furnaces, the use of Sil-O-Cel Super Brick often permits a reduction in the thickness of first-quality fire brick.

In this and succeeding pages, insulation for heated lines will be treated. Recommendations for in sulating coid lines will be found on page 16. J-M 85% Magnesia Pipe Insulation (For Temperatures to 600 F.) Under actual service conditions, 85% Magnesia has proved to be the most durable and efficient insulation of the molded type. The J-M manufacturing process produces an 85% Mag nesia with the maximum number of voids or minute dead-air cells which increase its natural resistance to heat transmis sion and reduce its weight. In addition, it provides maximum mechanical strength consistent with high insulating efficiency. Joh.vs-Ma.nmux recommends 85% Magnesia as the most generally satisfactory and economical material for insulat ing steam lines at temperatures up to 600* F. For superseated steam at temperatures above 600* F., J-M-85% Mag nesia is often used outside a layer of Superex, as described under the subject of Superex Combination Insulation, on the following page. J-M 85% Magnesia is furnished in 3-ft. sections and seg ments in the following thicknesses: Standard (which varies from ? to 14 in., depending on pipe size), 14, 2, 24 in.; J-M 85% Magnesia on Steam Lines Boiier room of tKe ?-arc'ean Mcnai'ery Wa,h:no-sr>. 0. C. Double Standard (two layers, each Standard thick); and 3 in. (double layer for broken joint construction). Also fur nished in blocks (see page 5). J-M Asbeste-Spenge Felted Pipe Insulation (For Temperatures to 700s F.) Asbesto-Sponge Felted is not only the most efficient com mercial pipe insulation for temperatures up to TOO* F., but it is also the most durable. It is practically abuse-proof, stand ing up indefinitely under vibration and wear and tear that quickly affect other materials. It retains its high insulating value unimpaired over long years of service. Though some what higher in first cost than other materials, it has proved m many cases to have the lowest cost per year of any insula tion made. And it can be removed and replaced many times without loss of efficiency. Asbesto-Sponge Felted is built up of felts composed of asbestos fibre and small particles of spongy, cellular material, there being about 40 laminations per inch of thickness. The large number of dead-air spaces and interposed surfaces ef fectively break up heat flow and are responsible for the un usual insulating properties of the material. It is particularly well adapted to service on outdoor lines in oil refineries, steel mills, etc. For such uses it is furnished with a 3-ply integral waterproof asbestos jacket. The dura bility and weather-proof properties of the material are best demonstrated by the fact that the use of Asbesto-Sponge Felted with Waterproof Jacket is practically standard on railroads for covering the heating lines that run from the engine back underneath the cars. In such service it is sub jected to constant vibration and to rain, ice and sub-zero weather.

Wherever steam temperatures exceed 600* or 700` F., Johxs-Manvuxe recommends Superex Combination Pipe Insulation--a first or inner layer of Superex covered by a layer of J-M 85% Magnesia or Asbesto-Sponge Felted. In this construction, Superex is used as protection for the other in sulation which, although high in insulating value, is com paratively low in heat resistance. This method is now prac tically standard where temperatures are above the range of 85% Magnesia or Asbesto-Sponge Felted when not so pro tected. Banroc Pipe Insulation (For Temperatures to 1000: F.)

MANYILLE PIPE INSULATION for n e a t e z: Lin J-M INSULATION RECOMMENDATIONS In general, all Dipes, fittings and flanges at temperatures below 600s F., except small fittings which are insulated with J-M No. 302 Cement, should be insulated with AsbestoSponge Felted or J-M 83% Magnesia to the thickness given in table below. Asbesto-Sponge Felted Pipe Insulation may be used, where service conditions warrant, up to 700* F. All pipes 14 in. and smaller, at temperatures above 600* F. (or above 700s F., if Asbesto-Sponge Felted is used), should be insulated with a single layer of Superex sectional pipe insulation 2 in. thick. Small fittings are insulated with J-M No. 302 Cement. For sixes larger than 14 in. at tem peratures above 600s or 700s F., Superex Combination In sulation is used. This consists of a layer of Superex next to the pipe, over which is applied Asbesto-Sponge Felted oi J-M 85% Magnesia, as required. The thicknesses below represent standard practice in gen eral use on heated lines. Exceptional conditions may make necessary thicker' insulation.

Where other insulation than Asbesto-Sponge Felted with integral waterproof jacket is used, the best weather protec tion for insulated pipe lines out-of-doors is a waterproof as bestos jacket of J-M Double Coated Flexstone fastened by rings of heavy non-corroding wire on 4 in. centers. DoubleCoated Flexstone is furnished in rolls of 108 sq. ft., 32 in. wide, weighing approximately 55 lbs. Where Tough usage may be encountered, a metal jacket may be used instead o: the weatherproof Flexstone jacket. Where exposed to fire hazard, the application of asphaltsaturated roofing jackets is inadvisable since flame may be carried along exposed piping when a fire occurs adjacent to lines so protected. In such cases it is good practice to apply a J-M Asbeatoe Firetard Jacket. The Firetard jacket consists of one sheet of asphalt-saturated asbestos felt over which is cemented an unsaturated felt. It will not drip asphalt, carry flame nor support combustion. It is furnished in rolls of 108 sq. ft., 32 in. wide, weighing approximately 50 lbs. 11 Johns-Manvflle INSULATING AND FINISHING CEMENTS Johns-Manvllle manufactures a complete line of Insulating and Finishing Cements, each designea for a specific purpose.

C-3 Concrete made pcssible to ut.hze insuiation "here previously it had been impractical to do so for structural reasons. The materia! can be ea;ily cast in mono lithic form for the construction of doors, baffles, dampers, etc., and, when suitably reinforced, may be molded into large units for such purposes. This semi-refractorv insulating concrete is made by mix ing four parts o: Sil-O-Cel C-3 and one part of Portland or lurr.mte cement, by volume, with sufficient water to form a plastic, coherent mass. Sil-O-Cel C-3 is a coarsely-ground, granular, semi-refrac tory. insulating prouuct, milled from diatomaceous silica (Celite) and calcined to withstand high temperatures with out shrinkage in service. Approximately 2S lbs. of Sil-O-Cel C-3 are required per cubic foot of finished concrete. Made in accordance with di rections. it sets up into a strong, durable concrete weighing approximately 6n lbs. per cubic foot and with a crushing strength of about 1,000 lbs. per square inch. Sil-O-Cel C-3 Concrete is over three times as effective as fire clay brick in reducing heat transfer. It has a high degree of refractoriness and can be used without other refractory protection where it may be subjected to direct heat as high as 1S00= F.

Such doors reduce heat losses, increase the output of the furnace, make temperatures more uniform and improve working conditions. Sil-O-Cel C-3 Concrete weighs less than half as much as fire brick and conducts less than one-third as much heat. Other Uses of Sil-O-Cel C-3 Concrete Sil-O-Cel C-3 Concrete is also an ideal material for insulat ing the bases of various types of heat-treating furnace-. k..i.-. oil still furnaces, hot blast stoves, open hearth furnace re generators and flues, and many other types of high tenipv jture equipment. Insulating the bases of such equip men; rot only saves fuel but also insures more uniform heat 'i:-;r.i,ution within the equipment and protects the foundation from excessive heat. It is an excellent material for making up special -k.u; such as baffles, dampers, etc. It is also cast into cov. - for wheel annealing pits; for the construction of fire .-ere*::- to protect men working in front of open furnace door;: and for a great variety of other uses. Such equipment as japanning and enameling oven-, core ovens, etc., are often constructed entirely of Sil-O-t'e! C-3 Concrete. Ovens of this type can be built and operate,! at great saving over the ordinary type of masonry con.-truct.on.

Sil-O-Cel C-3 Concrete is also adaptable for insulating the outside of walls of equipment which had been constructed without insulation. It can be applied very satisfactorily with a cement gun to steel surfaces or the brick walls of existing equipment. 13 Johns-Monville INSULATING FILLERS 1+ is ordinarily preferable to use insulation in the form of blocks, bricks or pipe sections. In some in stances, however, conditions render impracticable the use of solid insulation and then insulation fillers are adapted to serve the purpose. Sil-O-Cel C-3 A coarse, gTanular calcined diatomaceous silica (Celite). used as an insulating filling on high temperature equipment, particularly where lack of space prohibits the use of any but relatively thin fire brick linings and where the insulation is therefore subjected to very high temperatures. A typical application of this material in dry form is in the bases of oilfired marine boilers. This material is also used in making Sil-O-Cel C-3 Concrete, as described on a preceding page. Temperature limit, 2000 F. Weight loose, 28 lbs. per cu. ft.; packed 31 lbs. per cu. ft. Furnished in 100-lb. bags. Sil-O-Cel Coarse Grade Coarsely ground diatomaceous silica (Celite), used as an insulating filler. Temperature limit, 1600 F. Usually packed to density of 22 lbs. per cu. ft.

Banroc Loose A loose rock wool fibre used as an insulating filling in ovens, fireless cookers, electric and gas ranges and similar equipment. Temperature limit, 1000 F. It is packed in place to the required density; usually 12 lbs. per cu. ft. is sufficient. Furnished in 50-lb. bags. Can also be furnished granulated (Banroc Granulated) in 50-Ib. bags, the recommended density of which is 9 to 10 lbs. per cu. ft. poured, or 10 to 12 lbs., packed by hand. Johns-Monville WATERPROOF FINISHES FOR INSULATION Insulkote Insulkote is a durable, easily applied weather-proof coat ing for insulation on outdoor smoke breechings, ducts and other exposed insulated equipment. It stands up under ex treme weather conditions and remains sufficiently elastic to prevent its cracking. Furnished in ready-mixed, plastic form and of suitable consistency to apply with a trowel. Applied in one coat h in. thick, it covers about 45 sq. ft. per 100 lbs. Furnished in 50-lb. pails and in 150, 300 and 500-lb. drums. Aertite Coating Aertite Coating is a tough, rubbery, asphaltic-asbestos coating in plastic form, often used like Insulkote for weather proofing insulation outdoors. Its primary use, however, is for coating boiler walls to prevent air infiltration. For a ' in. coat, 50 to 80 lbs. are required per 100 sq. ft., depending upon character of surface. Furnished in 25, 50, 130, 300 and 500-lb. containers. (For waterproof finishes over pipe insula tion, see page 11). 14 Johns-Manville ROCK CORK SHEET INSULATION FOR LOW TEMPERATURES Because Rock Cork has a successful service record extend* ing for more than a quarter of a century, Johxs-Manville recommends it as an efficient and economical insulation for cold rooms, ducts and refrigerating equipment. The earliest installation, made in 1907, is still in service and in excellent condition. The refrigeration load has not increased during 29 years of continuous sen-ice, indicating that the original high insulating value of Rock Cork is maintained indefinitely. Made of rock wool combined with a waterproof binding in gredient, Rock Cork is mineral in composition; highly mois ture-resistant; permanent; rot-proof; chemically inert; odorless and incapable of absorbing odors. Completely sani tary, it will not harbor vermin or rats and cannot support the growth of mold or bacteria. With its myriads of tiny air spaces completely sealed with the waterproof binder, Rock Cork stubbornly resists the infiltration of air and moisture, thus eliminating this direct cause of most insulation failures. No other low temperature insulation is as effective as Rock Cork in resistance to moisture absorption. More than any other one feature, this distinctive characteristic has been re sponsible for the outstanding service record of Rock Cork. J-M Rock Cork is furnished in standard sheets: 18 x 36 in., in thicknesses of 1H, 2, 2Vi, 3 and 4 in., and 18 x 18 in., in 1 in. thickness. Other sizes, within the above limitations and of standard thickness, can be furnished on special order. The sheets weigh approximately 1.3 lbs. per sq. ft. per inch of thickness and are packed in cartons containing 54 board feet. Rock Cork in lagging form for curved surfaces is supplied 18 in. long, 1*2, 2, 3 and 4 in. thick, and 2 to 5 in. wide, de pending on diameter. Rock Cork at Swift and Company, Atlantic City, N. J. Because their earliest installation in I9C9 is stii! m oenect cons * Swift and ComDany continue to use J-M Rocs Cork. In the latest ,oc appited late in 1934 at a new prencn house at Atlantic City. N. J.. Rock Cork was used throughout. Rock Cork is also manufactured in granular form for use as a loose, moisture-resisting fill type of insulation. Granu lated Rock Cork should be packed to a density of 13 to 14 lbs. per cu. ft. Furnished in 35-lb. paper bags and burlap bags of random weight. For data on Rock Cork in the form of pipe insulation see the following page. RECOMMENDED THICKNESSES OF J-M ROCK CORK J-M Rock Cork Shoots aro Efficient, Permanent and Economical While many factors, such as the cost of refrigeration and local atmospheric and temperature conditions, may govern the amount of insu lation which should be used, the thicknesses of Rock Cork sheets or lagging given in the following table are rec ommended for general re quirements : Temperature range, deg F.

Rock Cork Pipe Insulation In Bock Cork Pipe Insulation, Johns-Manville now makes available for the lirst time an insulation for low temperature pipes that combines with the proved permanent high effi ciency and unequalled moisture resistance of Rock Cork Sheets the added protection of hermetic sealing--a further protection against any infiltration of moisture-laden air, the cause of most low temperature insulation failures. At the factory-, each section of Rock Cork Pipe Insulation is coated with waterproofing asphalt into which is firmlyembedded a waterproof jacket that becomes an integral part of the pipe covering. This jacket is provided with a lap which is sealed down over the longitudinal joint at installation.

J-M Built-up Brine and Ammonia Pipe Insulation This J-M insulation is efficient in maintaining the extremely low tempera tures required in pipe lines conveying brine, ammonia or other cold liquids or gases. It consists of two or more layers of insulating felts carefully applied and sealed. The effective method of sealing eliminates the possibility of moisture accumulating between pipe and insulation and then freezing and bursting the insulation. The material is not only highly efficient as an insulator, but will withstand contraction and expansion without cracking or breaking open. This type of built-up insulation to be satis factory should be ap plied only by mechan ics specially trained in low temperature work. Johns-Manvilix Ap proved Contractors are experienced in such applications.

The following recommendations are based on Johns-Manville's many years of close co-operation with the Steel Industry in the control of heat losses. For complete insulation specifications and drawings covering all types of blast furnace and steel mill equipment, ask for the J-M handbook "Johns-Manville Service to the Iron and Steel Industry." The Blast Furnace System Blast Furnace Stack: For stack insulation Johns-Manville recommends from 2`j to 4 in. of Sil-O-Cel Coarse Grade, (see page 14) installed between the brickwork and the shell from the mantel to the bottom of the wearing plates. Because of the more uniform temperature gradient, vapors of zinc or other impurities in the ore are prevented from chilling and condensing in the iining, but instead are carried through into the insulation, where condensation takes place in the highly porous Sil-O-Cel. The insulation also protects the shell against excessive temperatures. Hof Blasf Sfevcs: From 5 to 7 in. of Superex Blocks (see page 6) are recommended for hot blast stoves. The unusual heat resistance of Superex ordinarily permits the thickness of refractory to be re duced by one 4^2-in. course. Domes are insulated with 4*2 in. of Superex Blocks. Base insulation consists of a minimum of 4 in. of Sil-O-Cel C-3 Concrete (page 13). This method of insulation pays for itself in a few months' operation. Furthermore, stove capacity is increased and checkerwork lasts longer. Hot Blast Mains, Bustla Pipes and Valves: The generally recommended insulation for hot blast mains and bustle pipes is a 3 in. layer of Superex Block or a 4)2 in. course of Sil-O-Cel C-22 Brick behind a 4*2 in. course of fire brick. Either of these construc tions reduces radiation loss 60 to TO per cent compared to that from an uninsulated 9-in. fire brick lining. Superex Block and C-22 Brick are also recommended for insulating valves. Johns-ManvilU Insulation Recommendations for Hot Blast Stoves and Mains U'. Bustle Pipe Insulated with Sil-O-Cel C-22 Brick J-M Insulation used also in the stack, stoves, mains and valves assure aconomteai operation of the entire system. 18 The Open Hearth Plant Furnace Proper: The many steel m.!'- now operating completely insulated open hear:! - im port greatly reduced operating co-t.-.

Sections below ground are in sulated with 4 in. of Sil-O-Cel C-3 Concrete which is also the recommendation for the ba?es of regenerators, fan-tails and slag pockets. The walls of fan-tails and slag pockets are insulated with 4in. of Sil-O-Cel C-22 Brick or Sil-O-Cel C-3 as a granu lar fill. For fan-tail roof: the same materials are recom mended. 2'j in. thick. Open hearth flues are completely insulated in bases, sides and over the top with at least 4 in. of Sil-O-Cel C-3 Concrete. On existing regenerator? with irregular wall surfaces, J-M No. 500 Cement or Sil-O-Cel C-3 Concrete is used instead of brick or block insulation.

Not only does it pay for itself in fuel savings in an amazingly short time, but it also makes possible closer temperature control, reduces air infiltration, assures better working conditions and, in many cases, appreciably improves the quality of the product turned out by the fui r.uce Despite the fact that less than 23 years have clan-ei sir J-M high temperature insulating materials fir--, made nace insulation possible, the advantages of thorough tion are now universally recognized. Large quant:::*.- of:S J-M Products are now used to minimize furnace oj-e:.:.costs in every major country in the world. FURNACE INSULATION METHODS In the higher temperature furnaces, operating above 2000a F,, Superex Blocks, Superex-Magnesia Combination Blocks, or Sil-O-Cel Brick are usually applied behind the re fractory in walls and over the fire brick roofs. These mate rials are described on pages 3 to 8. For bases, Sil-O-Cel C-3 Concrete (page 13) is practically standard construction. Where furnace temperatures are not over 2000" F., Sil-OCel C-22 Brick is recommended as the inner lining of walls, roof, base and door. This method reduces construction costs, improves furnace performance and minimizes radiation losses. On intermittent furnaces, it also effects enormous sav ings in heat capacity losses, permits of faster heating up and, in many cases, faster cooling as well. Th..- con.-tru.-..: is described in greater detail on page S. For door linings at temperatures up to lSi'O" F.. S.I-O-l C-3 Concrete is more widely used than any otner rr.uier.. (see page 13). The most economical thickness of insulation will vary the temperature, type of heating employed and me ogiee c temperature control required. It may vary from 2 or 3 ;r on a coal-fired billet-heating furnace to 20 in. or more o electric furnaces.

The in sulation saves fuel, increases production, assures better tem perature control and protects the steel shell. Roosters: The Wedge multiple hearth roaster is insulated throughout with Sil-O-Cel Powder and Sil-O-Cel Natural Brick, as indicated in the accompanying drawing. The Nichols-Herreshoff type of roaster is insulated on the walls and bottom hearth as in the Wedge type. Roaster up-takes are insulated with 2':" of Superex Blocks or Sil-O-Cel Natural Brick. Hot calcine pipes between the roaster bottom hearth and the calcine hoppers are insulated with 2Ij" of Superex Blocks or Sil-O-Cel Natural Brick. The calcine hoppers are insulated with 21!" courses of Sil-O-Cel Natural Brick in the sides and bottom and with one 2Id" course of Sil-O-Cel Brick over the crown. Dust Collecting Equipment Flues are insulated to protect the flue itself as well as to maintain the temperature of the gases. Because of the vary ing temperatures due to the widely differing process de mands, each installation should be considered as a separate problem. Comparatively short internal flues are usually insulated either outside or inside with Sil-O-Cel Brick or Superex Block. Long outdoor flues usually require thick insulation because of the additional exposure to temperature changes. Some times the insulation is applied internally, as on one large job where a steel flue was insulated with 5* thick Superex Com- ML-o-cttmTwuL amcx 7% SIL-O-CEL !--NATURAL BRICK J-M Insulation Recommendations for Wedge Multiple Hearth Roaster bination Block Insulation protected against erosion by 1" of J-M No. 319 Semi-Refractory Cement. On other jobs Superex Blocks and Sil-O-Cel Natural Brick have been used on the outside of the flue, waterproofed with a roofing jacket. Cottrell Precipiteten: The steel housings of Cottrell pre cipitators are usually jacketed and filled with 3" to 4" of Sil-O-Cel Coarse Grade. Over the tops 2V* or 5" of Sil-OCel Natural Brick or 2*i" to 4" of Superex Blocks are used. Inspection doors are usually insulated with Sil-O-Cel C-3 Concrete not less than 4* thick. Dust hoppers have been insulated on the inside with a 2Vi" course of Sil-O-Cel Natural Brick protected by a course of fire brick. Cottrell discharge pipes are usually insulated on the outside with a 2`i" course of Sil-O-Cel Natural Brick or Superex Blocks. Refining Equipment A noteworthy example of the effectiveness of insulation ithe 90-ton remelting furnace for lead bullion at the Midvale smelter of the U. S. Smelting, Refining and Mining Co. Daily use over a long period necessitated no repairs and, owing to the efficiency of the insulation, this furnace consume- no more coal in melting 90 tons of lead than do the uninsulated furnaces in melting 30 tons. The method of insulating t.shown in the drawing opposite. Sil-O-Cel materials and Superex Blocks are also widely used for such equipment as aluminum reducing furnaces, zinc distillation furnace regenerators, as well as the melting and heat treating furnaces used in the fabrication of non-ferrou* metal products.

The present-day efficient utilization of heat in transforming crude oil into finished petroleum prod ucts is due in no small measure to the close association of Johns-Manville with oil industry problems and to the development by J-M of insulating materials and methods designed to minimize operating costs. J-M recommendations for the insulation of oil industry equipment can be only briefly touched on below. A 208-page book, "Johns-Manville Service to the Oil Industry," contains complete insulation specifications and detail drawings for every type of heated or refrigerated equipment involved in production, transportation, refining or processing. In Oil Production Field Boilers: l>i in. thick J-M 85"* Magnesia blocks, waterproofed with 1* in. Insulkote, is the preferred specifica tion for field boilers. J-M Asbestos Blankets. 1 in. thick, are used where a removable and replaceable insulation is desired. storage Tanks: Evaporation losses have been minimized on thousands of storage tanks by the special J-M Vapor-Tight Insulated Tank Top, complete details on which are included in the book, "J-M Service to the Oil Industry." In Oil Transportation Tank Cars: Johns-Manville has developed a number of specifications for tank car insulation with J-M Standard Hair Felt-and Asbesto-Sponge Felted Blocks. Complete details, in cluding data on heat losses through various constructions are contained in "J-M Service to the Oil Industry," sent on re quest. Pipe Linns: Where pipe lines must be insulated to pre vent reduced capacity during cold weather, Asbesto-Sponge Felted Pipe Insulation with Integral Waterproof Jacket is recommended. Thousands of miles of underground pipe lines have beer protected against corrosion with J-M Asbestos Pipe L:r., Felts. Full details on request. Pumping Stations: For insulation of pumping station boilers, see page on Power Plant Insulation. Steam pipe in sulation is treated in detail on pages 9 to 11. In the Refinery Stills and Fractionating Equipment: Asbesto-Sponge Felted, J-M 83% Magnesia and Superex Combination Bioc. Insulation are the most widely used insulating material- to: the exposed heated surfaces of stills, towers, and other tionating equipment. The insulation is finished with J-M No. 302 Cement and waterproofed with Insulkote. Insulation thicknesses are generally those given in the table of recom mendations on page 7. "J-M Service to the Oil Industry" carries a complete chapter on this subject. Furnaces: Oil refinery furnaces are usually insulated out side the refractory with either Superex Blocks or SuperexCombination Block Insulation. On most installation- the thickness has been approximately 4 in. Transite Asbestos Sheets, described on a later page, have been widely used by the oil industry as a furnace casing over the insulation, because they are fireproof, weather-proof, and maintenance-free. Sil-O-Cel C-22 Brick, 4': in. thick, are also often used as a "core wall" between the fire brick and red brick. Sil-O-Cv! Natural Brick may be used opposite the cooler portion* of the furnace. For furnace bases, 4 in. of Sil-O-Cel C-3 Insulating Con crete has proved highly effective. This material is also u.-e.l for the insulation of tube doors and to protect metal work on tube plates and tube supports. Hot Tanks: J-M 85% Magnesia Blocks are the standard recommendation for hot tanks, applied in the following thick ness on the sides (Vi in. less on roof): 100 to 300' F.. 2 in. thick; 300 to 400" F., 2*.i in.; 400 to 500* F., 3 in.; 5u0 to 600" F,, 3 S in. A Transite Casing or Insulkote finish is rec ommended on the sides. The roof insulation is covered with asbestos water-proofing felts with a layer of J-M Salamander White Top Roofing as a finish. Cold Tanks: J-M Rock Cork sheets or lagging are used for sides and roofs of cold tanks in the thicknesses recom mended in the table on page 16. The insulation is weather proofed as outlined above for hot tanks. Brin* Coolers, Chillers, Cold Rooms, etc.: A com plete chapter in "J-M Service to the Oil Industry" is devoted to the insulation of low temperature equipment and cold rooms with J-M Rock Cork Sheets and Lagging. Cold Piping: See page 17. Boilers and Other Power Plant Equipment: see page on Power Plant Insulation. On* of Many Refineries Where J-M Materials are Everywhere in Evidence Steom and Hot Oil Lines: Asbesto-Sponge Felted is the ideal pipe insulation for the oil refinery, not only becau.-t- of its high efficiency, but also because of its great durability and unusually high salvage value. For use on outdoor lint* ;t i.fumished with an integral waterproof jacket. For data on J-M Pipe Insulation, see pages 9 to II. 22 Johns-Manville Insulation Recommendations lor CEMENT AND LIME PLANT EQUIPMENT In connection with the manufacture of portiar.d cement and lime, Jcnns-Manville Insulations are used for the kilns and power plant equipment, as well as for the ser+iinp champers on rotary kilns and the waste heat flue systems. Rotary Kilns Rotary kilns represent, perhaps, the most severe service that insulation is ever called upon to withstand. In addition to high temperature, there is rotation, vibration, abrasion.

Settling Chambers and Waste Heat Flues For settling chambers and waste heat flues Johns-Man ville recommends insulation with 41: in. of S;l-0-Cei Natural Brick or 4 in. of Superex Blocks in walls: 3 in. of Sil-O-Cel Natural Brick or 4 in. of Superex Blocks over tnc top; and 4 in. of Sil-O-Cel C-3 Concrete in the base The-- materials have been used for insulatine settling charr.be; and flues in practically every waste heat installation in the cement industry. Vertical Lime Kilns Insulation of vertical lime kilns not only quickly pay; for itself in fuel savings but also assists in the production of clean, white lime with no `'core" or un^lakable lumps. For the fire box, 4H in. of Sil-O-Cel C-22 Brick are recom mended behind the fire brick. The balance of the kiln may be insulated with 5 in. of Sil-O-Cel Natural Brick or 4 m. of Superex Blocks. Sil-O-Cel Coarse Grade is also sometimes used. Producer Gas Mains Producer gas mains should be insulated with 2' j to 4 .r. of Superex Blocks or a or 4's in. course of Sil-O-1'.! Natural Brick. Insulation soon pays for itself in fuel min ings and also minimizes tar deposition in the mains. Boilers, Piping, Etc. Insulation of boilers and other power plant equipment i.treated on a later page. Pipe insulation materials and recom mendations will be found on pages 9 to 11. expansion and contraction of the fire brick lining and the continued impact of the heavy mass of clinker. Since 1924, however, when the first rotary kiln was insu lated with J-M Superex, the cement industry has been able to take advantage of the savings which insulation makes possible. And the many kilns insulated since that time, in accordance with the same specifications, are returning year after year large dividends in fuel savings. The Johns-Manville insulation specification which has proved so successful for rotary kiln insulation is shown above. Insulation is omitted at the hot end for a distance equal to about 23% of the kiln length. In wet process kilns where filters arc not used, the insulation is also omitted for a distance of 20 ft. at the wet end. The results obtained in the Clinchfield, Ga., plant of the Pennsylvania-Dixie Cement Corporation are typical of those reported for other mills. At this plant careful fuel consumption records showed that Superex Blocks on two 10 ft. x 17j ft. kilns reduced coal consumption 5 lbs. per bbL of cement, a saving of 54.800.00 per year, representing an annual return of 120% on the investment in insulation. It should be noted that this figure does not include further Camant Mill Wait* Haat Ru# Baing Intulatad with Two 2-inch Layars of Suporox Blocks Johns Insulation Recommendations lor GLASS MAKING EQUIPMENT Insulation plays an important part in the manu facture of glass, not only in connection with the melting operation itself, but also in annealing and other processes where heating is involved.

Thickness may vary from 4 or 5 m. for cheap fuel up to ij m or even 20 in. where electricity is used. Melting Tanks Whether or not insulation should be used on walls and crowns of glass tanks is a question to be considered specially for each individual job. This matter is now receiving a great deal of attention in the Glass Industry, due in part, perhaps, to the excellent results which have attended the use of insula tion on open hearth roofs in the Steel Industry. There are a number of J-M insulations, including Superex Blocks, Sil-OCel Brick and Powder, and J-M No. 500 Cement, which will successfully resist the temperatures encountered outside the refractory. Sil-O-Cel C-22 Brick on the refining end of continuous tanks offers an excellent opportunity for fuel sayings which should be possible for every plant. In day tanks also, insulation has been used with uniformly beneficial results. A 4 Vs-in. course of Sil-O-Cel C-22 Brick in the walls and a 2 Vi-in. course in the base and over the crown will shorten the melting time, reduce fuel consumption and minimize troubles due to devitrified or cordy glass.

Insulation effects marked savings in pro duction cost and also improves the quality of the ware by assuring more accurate temperature con trol and more even heat distribution. Furthermore, it permits kilns tc be brought up to heat more rap idly and held at the desired temperature more easily. Periodic Kilns Wherever comparative fuel consumption records have been kept, insulation has been shown to be a decidedly worthwhile investment. In one instance, Superex Blocks over the tops of rectangular kilns returned their entire cost in fuel sav ings alone during the first year. Such savings (15,000.00 for six kilns in this particular case) are within the reach of any plant now operating uninsulated periodic kilns, for crown in sulation can usually J/L-O-CSL COA03I 6**Q--' be applied just as easily and economi cally on old kilns as on new construction. Insulation on crowns alone has in every case shown a reduc tion in fuel consump tion of at least 10%.

Rotary Boiler Insulation The Biggs Rotary Bleaching Boiler offers a good example of how savings may be made in the paper mill through insu lation. For this equipment Johns-MaXVILLE recommends IV J-M 85"c Magnesia Blocks with a finish of J-M No. 302 Cement. This method of insulation, according to careful cal culations of comparative heat losses, will pay an annual re turn on the investment of about 60^ even when fixed charges against the insulation are based on amortization in only 5 years. A complete analysis of these savings, together with de tailed specifications and drawings covering insulation with J-M 8o^c Magnesia Blocks will be furnished on request. An alternate specification for insulation with J-M No. 430 Cement, sometimes used for the purpose, is also included. J-M Insulated Rot-Proof Roof The J-M Insulated Rot-proof Roof was especially designe I to withstand the severe humidity conditions encountered ov.: paper machine rooms. The base for this roof is J-M Corru gated Transite, which is first laid directly over the purlin.-. The corrugations are leveled with cork mastic, after wr.ich a layer of sheet cork is applied and finished with a J-M AsbestoBuilt-up Roof. Many paper mills are now using this roof over machine rooms to minimize roof drip and periodic shut-down- fo: repairs and to insure permanent, waterproof protection Applying J-M Insulated Rot-proof Roof Transite Paper Machine Hoods These hoods are highly effective in increasing drying capacity, in decreasing the amount of air required for tl.e drying operation, and in lowering the humidity of the paper machine room. Transite hoods are fireproof, highly acid-re sistant. unaffected by heat and water, and require no main tenance. When insulated they provide still greater (trying efficiency. Paper Mill Steam Lines Insulated with J-M Materials When power p:ant eouipment is modernized end pressures increased, steom lines usually reouire thicker insulation. Digester Insulation For the insulation of digesters J-M 85rf Magnesia Blocks, l's" thick, with J-M No. 302 Cement finish, is the preferred specification. J-M Asbestos Blankets are also sometimes used because of the ease with which they can be removed and replaced. Eel-Slip--A New Bearing Material Made of asbestos, graphite and rubber, this new bearing material for paper mills is as slippery as its name implie.-. Water is its best lubricant, and when running wet the co efficient of friction is unusually low, approximately .nl'i. Many paper mills are already using Eel-Slip for increased efficiency and economy on the wet end of Fourdrimer and cylinder machines--for shaker or flat screen blocks, water tables or forming boards, suction box covers, steam joint-, suction couch and press roll packing, deflector strips and doctor blades. Full information will be furnished by any Johns-Manville office. 27 \ r Johns-Monville Insulation Recommendations for BREWERY EQUIPMENT To operate economically and on a competitive basis, the present-day brewery must be equipped to take advantage of proved modem methods of decreasing production costs. In every industry where heat or refrigeration is utilised, ade quate insulation has, during the past fifteen years, come to be recognized as a vital economy measure and one of the major essentials to efficient operation. Insulation of low temperature equipment and storage rooms is especially important because of the high cost of refrigera tion. Furthermore, temperatures must be controlled within a relatively narrow range, a condition which cannot be main tained without adequate insulation. In the case of heated equipment, fuel cost is one of the principal items of expense and the problem of heat conserva tion is a matter of major consequence. In the boiler room. insulation of the boiler furnaces reduces radiation lo-- minimizes air infiltration and assures better working cor. : tions. Insulation on boiler drums and steam lines pay.- :c itself many times over in fuel savings. Brew kettles, cereal cookers, mash tuns, hot water tar.. and similar equipment, all can be made to operate more eco nomically by the careful selection and application of insulat ing material of the proper type and thickness. Whether heating or refrigeration is involved, whether the surface requiring insulation is a pipe, kettle or the wah of a storage room, there is a J-M product which will serve the purpose effectively and economically. In the table which follows, J-M recommendations for insu lation in the brewery are briefly summarized. Now Browory of E. B J. Burts, Ltd., Built in 1933 at Long Island City, N. Y.

J-M Refractory Cements --2,e''=a,iv reouce refractory maintenance. Used to bond fire brick and to wash-coat refractory wails. J-M Refrac tory Cements minimize refractory maintenance by protecting the edce- of the brick from the action of flame and molten ash and by reducing cimke: ing, slagging and spalling. Refractory Cements also cut down heat lo.-.-.-because open joints between the brick, a common condition where ordinary fire clay is used, are eliminated; the insulation is protected from furna.c gases; and air infiltration through joints is effectively prevented. Out of the entire J-M Refractory line there are four materials which meet the requirements of the bulk of refractory work for bonding. aihcoating, patching and monolithic construction. These four are No. 31, No. 32, Hellite and Firecrete, the application? of which are described on this and the following page.

Aluminum silicate base; vitrifies at 1250' F. and useful up to 3100' F. As a mortar J-M No. 32 has excellent plasticity, handles easily and stands well in suspension. Thinly mixed it is an excellent wash coating for brickwork set with J-M No. 31 or No. 32 cement. Hellite For brick setting and wash-coating with a ready-mixed air-setting camant The best material for these purposes is J-M Hellite, an easily workable, finely ground, air-setting cement which makes strong, permanent joints. As a wash-coating, it in creases the resistance of the firebrick to gases. It is also highly recommended for hot patching with paddle or gun. It has high adherence, minimum shrinkage and will not "bloat" on rapid heating. Temperature limit, 3000 F. Firecrete A new hydraulic cement for monolithic refractory construction Firecrete is shipped in the form of a dry cement. Mixed with water on the job it can be used for either tamped or poured linings for doors, pipes or flues and for poured or cast baffles, dampers and special shapes. Handled like ordi nary concrete, this new hydraulic-setting refractory cement has greatly simplified many types of refractory construction which were difficult and expensive to carry out with standard fire brick or special refractory shapes. Firecrete is excep tionally strong and highly resistant to spalling, with prac tically no-drying or firing shrinkage. Firecrete is furnished in the following three types: Stan dard for temperatures up to 2400' F.; H. T. (High Tempera ture) for use up to 2800 F., and L. W.

Light Weight Firecrete, 40% lighter in weight than fire brick, is the latest development of the J-M Refractory liesearch Laboratory. With 40% lower heat storage capacity than fire brick, it is particularly suited for use in intermit tently operated furnaces because of the speed with which trm furnace can be brought up to temperature and the fact that 40% less heat is wasted as the furnace cools. Its low thermal conductivity, less than half that of fire brick, also recom mends it for continuous furnaces. Light weight, combination insulating and refractory doors and roofs for furnaces repre sent two of many important applications for this unique material. Further details will be sent on request. 3d "v Johns-Monville FLOORING MATERIALS Jonrs-Marviile Fleering Products include a light weight, tough aspna'r:c plank for industrial floors, and attractive, coiorful asphalt tiles which provide a duraDie :;oor covering for offices and other loca tions where truck traffic or heavy loads on concen tratec oeari^o areas are not encountered. J-M Industrial Fleering Plank The ideal factory floor should be strong, durable, practi cally wear-proof. It should be resilient yet capable of support ing heavy loads. It should be quiet, dustless, fire retardant, vermin-proof, odorless, and it should not check, chip, warp or decay. J-M Industrial Flooring Plank possesses all of these qual ities. and more. It is rapidly and easily applied and is ready for use a; soon a; it is laid. Should any part of the floor be seriously injured through accident, the damaged planks are quickly replaced and the repaired section is ready for traffic immediately. This type of industrial flooring requires little or no maintenance. The plank is made of a mixture of tough fibre, high melting point, low penetration asphalt, and graded mineral filler, densely compressed and die-cut into rectangular planks or slabs, 12 x 12 in. and 12 x 24 in. in Vi, H and 4 in. thick nesses. The material is available m three colors--red, brown and black. J-M Industrial Flooring Plank is recommended for use on warehouse and manufacturing floors where a suitable sub floor exists and where unusually heavy loads do not rest or. small bearing areas. This material has successfully withstoc : the highly abrasive foot traffic encountered m subway cu: and the heavy trucking and static loads of railroad fro. houses. It has been used in parking areas and on rami;.-, on the floors of passenger vehicles and lifts, throughout auto mobile and other industrial plants, in cold storage and otr.cr warehouses and on busy wharves and dock*.

Jonns-Manviiie Has aev-ioceo a numbe* of a ferenr tyces of buiit-uo roofs and is in a position to furnish a roof to meet practically any con dition or personal preference. THe various stanaard J-M Built-uo Roofs are listed on following cages. These roofs are classi fied on the oasis ct --e Wi~d of felt and number of levers used in their construe* on. T-e tacies also ino:cate rne ratings of rne Unaerwnrers' Laborateres. Inc. J-M BONDED ASBESTOS BUILT-UP ROOFS J-M Bonded Asbestos Built-up Roofs are the outcome of several decades of study and expe rience in producing durable, fireproof, weather proof, light-weight roofs at a moderate cost. They are suitable for industrial buildings, ware houses, office buildings, hotels, hospitals and apartment houses. J-M Smooth-Surfaced Asbestos Built-up Roofs While Johns-Manville furnishes built-up roofs of every type, the smooth-surfaced as bestos roof is recommended as the one best de signed to stand up under all ordinary conditions and to give complete trouble-free protection for the life of the building. This roof is built up of alternating layers of asphalt-saturated asbestos felt and roofing asphalt. Applying J-M Rigid Roofinsul in Three l/j-inch Layers Roof tnsuiar-on not only saves fuel and assves cc--fo--afcie integer te--ee-a'-'ti J-M Asbestos Felts, with which J-M Bonded but also protects botn the roof aeck and the Ouiit-uo roof. Asbestos Roofs are built up, will not support combustion even when impregnated and coated with as phalt. The Underwriters' Laboratories, Inc., give Class A ratings to both J-M Super Class A and Class A Asbestos Roofs. They are fire-resistant to the highest degree. But the most important advantage of asbestos is its pro nounced effect in assuring roof permanence and freedom from maintenance by the preservation of the waterproofing tar or asphalt. The heat of the sun on other types of roofs draws up the underlying tar or asphalt through the capillary channel- in the vegetable fibres themselves, bringing the life-giving lighter oils to the surface of the roof, from which they are lost by evaporation. Asbestos felt, because of the peculiar non-capillary nature of asbestos fibre, forms a positive barrier against this evap orating action. The waterproofing asphalt, both in the felt and between the plies, is preserved practically in its original condi tion, despite the intense drying-out action of the sun. Since asbestos, itself, is imperishable, an asbestos roof is the best assurance of roof permanence. There Is J-M Bonded Built-up Roof to Meet any Roofing Requirement J-M Bonded Roofing Asphalt J-M Bonded Roofing Asphalt--a relatively recent develop ment which has proved to be far superior to ordinary asphalt --is used on all J-M Bonded Asbestos Roofs. Tested at the Johns-Manville Research Laboratories at Manville, N. J., in the most modern types of weathering machines, Bonded As- 35 J.M BONDED ASBESTOS BUILT-UP ROOFS for any lcca~.cn phalt remained m perfect condition after being subjected to alternate cycles of heat, rain and freezing cold equivalent to ten years of actual service. Ordinary asphalts, tested at the same time, were seriously impaired in waterproofing effec tiveness. The unusual ability of J-M Bonded Asphalt to stand up under all conditions of service will add years to the life of a roof. Other Types of J-M Bonded Roofs In addition to asbestos roofs, Johns-Manville also sup plies Combination Roofs, composed of a rag base felt and asbestos finishing felts, and a complete line of slag or gravel surfaced roofs, employing tar-saturated asbestos felts, tarsaturated rag felts, or asphalt-saturated rag felts. All of these roofs are included in the tables on later pages. Application and Inspection As the best results are obtained only when the proper roof ing is correctly laid, Johns-Manville has appointed Ap proved Roofing Contractors throughout the country, basing these appointments on thoroughness of workmanship sr . financial responsibility. Joh.vs-Ma.vville also maintains an inspection service :r. connection with J-M Bonded Built-up Roofs. This serv.ce required in connection with every roof which is to be bonded, and is rendered before, during, and after application. Surety Roofing Bonds All Johns-Manville Built-up Roofs of whatever type will, when desired, be covered by a bond of the National Surety Corp., guaranteeing the performance of the particular roo: for a period of from 10 to 20 years, depending on the type of roof applied. This bond is issued only on roofs laid by Johns-Manville Approved Roofing Contractors ana m con nection with Johns-Manville inspection service. Where Johns-Manville Flashing Materials are used in conjunction with Johns-Manville Roofing, a flashing en dorsement for a 10-year period will be attached to and be come a part of the bond, under the same conditions imposed for the bonding of the roof. JOHNS-MANVILLE INSULATED ROOFS Insulation on industrial, commercial and institutional buildings is rapidly gaming acceptance as a decidedly eco nomical investment. In connection with its Bonded Built-up Roofs, Johns-Manville recommends insulation with J-M Rigid Roofinsul for the following reasons: First, it effectively retards the passage of heat through the roof, thus saving on fuel and air conditioning bills. Second, on new construction the use of Rigid Roofinsul makes it possible to reduce appreciably the investment in heaung and air conditioning equipment. Third, it permits closer control over interior temperatures both in summer and winter, assunng more comfortable, uni- form working or living condi tions throughout the year. Uniform interior tempera tures are also a vital necessity in the operation of many mod ern industrial processes. Fourth, Rigid Roofinsul pre vents condensation on the un derside of the deck and elim J-M Rigid Roofinsul inates discoloration of ceilings and the annoyance and damage caused by roof drip. Fifth, by preventing condensation, it protects the deck against rot and corrosion. When the deck is of concrete or other non-combustible material, J-M Rigid Roofinsul reduces the danger of cracking (commonly caused by sudden tem perature changes) and thereby tends to prevent moisture from reaching the reinforcing steel members. Sixth, it provides protection to the roofing felts themselves. All roof decks move to some extent under temperature changes. When this cycle of alternate expansion and contrac tion continues over a long period of time, any cracks m the deck may eventually be transmitted to the built-up roof unless there is an intervening layer of insulation. J-M Rigid Roofinsul not only minimizes movement of the deck by keeping its temperature more uniform, but also provides sufficient resil iency to take up strains due to any movement which does occur and prevents their transmission to the felts, thus pro longing the life of the roof.

It will give maximum reinforcing value and facilitate proper curing of the concrete through the maintenance of the orig inal water-cement ratio, at the same time effecting impor tant savings in application costs and in the reduction of waste material. The reinforcing element of Steeltex Floor Lath is com posed of 12-gauge cold-drawn electrically welded galvanized steel wire reinforcing mesh. This mesh is attached to a tough corded backing--the form element--by means of crimp wires which also space the reinforcing mesh at the proper distance from the backing to permit the concrete completely to sur round and embed the reinforcement. The weight of the poured concrete insures complete and uniform embedment without the labor of blocking up or of pouring the slab in two operations. The Steeltex corded backing is of ample strength not only to support the concrete while it is being poured, but also to afford a safe walking surface once the fabric has been at tached to the joists. Being water-resistant, the backing mini mizes loss of water and fine aggregate through leakage, with a further advantage in the protection it affords to the floors below. Droppings are minimized, clean-up expense is elimi nated, and work can proceed in safety even while the concrete is being placed. Properly installed, there is no excessive sag when con crete is being poured, which effects considerable saving. Also, because Steeltex Floor Lath extends in one piece across the entire panel or bay, it gives lateral stiffness, continuity of re inforcing and distribution of loads over a number of joists or beams. Equally Adaptable to Floors and Reefs The advantages of Steeltex . Floor Lath as a reinforcement and form for light-slab floor con struction apply equally in the con struction of concrete and gypsum roofs. The material is easily laid on sloping or curved roof surfaces and the fibrous backing is particu larly adapted to roof construction since it helps check condensation on the underside of the slab, thus protecting the steel joists, beams and plaster ceiling beneath.

Steeltex Floor Lath (a 3x4-in., 12-gauge, cold-drawn, elec trically-welded, galvanized wire fabric, attached to a waterresistant backing, furnished in rolls 4 ft x 12S ft.) shall be unrolled across the joists to the desired length from the outer or bearing walla of the building. Steeltex Floor Lath shall be fastened every 12 in. along the end joist with special clips. Steeltex Floor Lath shall be stretched taut longitudinally across the joists by a special stretcher, and clipped securely every 12 in. along the bearing to which the stretcher is at tached. Steeltex Floor Lath shall then be clipped to each joist every 24 in. on joists spaced 16 in. and over, and one clip or wedge per width of roll for joist spacing under 16 in.

This is more than ordinary "steel reinforcement." It is an electrically welded wire fabric of square or rectangular mesh, manufactured from a special high grade cold drawn steel wire of high tensile strength and proper ductile qualities. This welding produces an absolutely rigid connection at every joint. Distortion of the fabric is thereby prevented, and since there are no wraps, ties or dips where the members are joined, the concrete is allowed to flow freely around all parts of the reinforcement and completely cover every wire. The result is a perfect bond between concrete and reinforcement. The material is furnished in either plain or galvanized finish, in both rolls and sheets. The rolls are of such length as to provide an unbroken continuity of reinforcement ex- DIMENSIONS. SECTION AREAS AND WEIGHTS SUITABLE USES Style 1L Oumte. Composition Flooring. Fireproofing.

Like all Transite prod ucts, they are made of asbestos fibre and Portland cement, formed under tremendous pressure into a homogeneous, dense mass of great strength, toughness and durability. In addition to its advantageous structural qualities. Corrugated Transite is highly re sistant to acid fumes, alkaline vapors and ad verse atmospheric conditions. It will not bum, rot, corrode, shrink or otherwise deteriorate. Corrugated Transite is easily applied and requires no painting or maintenance of any kind. Accurate records indicate that Transite assures the longest building life and the low est per annum cost. Where Corrugated Transite is Used The applications of Corrugated Transite for roofing and siding are practically unlimited. Throughout the country hundreds of indus trial plants are built of this material. It is the leading fire proof product of corrugated type in use today for general industrial construction. Oil refineries, for example, use it for fireproof aprons and roofs over stills, and for housings of various types. On the railroads it is used for round houses, car shops, switch tow ers, way stations and freight houses. In mining and quarry ing, it is used as roofing and siding for hoist houses, loader and crusher sheds, storehouses, etc. In the chemical and metallurgical industries, Tran.-ite solves difficult building problems because of its comparative permanence where ordinary materials are quickly destroyed. Its unique combination of qualities have also led to its wide spread use for warehouses and docks, airplane hangars and exposition buildings. Because of its unusual strength. Corrugated Transite can be laid on purlins spaced 54 in., and on girts spaced 60 in. Sizes and Accessories The standard type of Corrugated Tran-ite Sheets has corrugations with a 4.2 in. pitch and a depth of 1'2 in. The thickness is approx imately 7/16 in. at ridge and valley of corru gations, and approximately 5/16 in. on tan gent. Sheets are furnished 42 in. wide and in lengths up to 11 ft. Weight approximately 4.75 lbs. per sq. ft. crated. Curved or ,-pecir.l cut sheets can be furnished on special order. Corrugated Transite may also be obtained with corrugations of 2H in. pitch and 1in. depth, in 42 in. wide sheets up to 8 ft. 6 in. long. For use with Corrugated Transite, the >ame material is also furnished in the form of ridge and comer rolls, and louvres.

It is aUo furnished made up into core plates, ducts, forge jacks, smoke jacks, etc. Transite does not become warped, distorted or weakened in service; in fact, it actually strengthens and toughens with age. It offers high resistance to acid fumes and severe weather conditions. It has withstood severe fire tests and is widely used where fireproof qualities are important. Paintinsr. finish ing or protection against deterioration is not required. Flat sheets are furnished 36 x 48 in. and 42 x 48 in., in thicknesses of H to 4 in., and 48 x 48 in., 48 x 96 in., and 42 x 96 in., in thicknesses of 3 16 to 2 in.

TRANSITE VENTILATORS At no place is the destructiveness of the elements more apparent than in ventilators. In a position exposed to the action of wind, rain, snow and ice from the outside, they are fre quently subjected to corrosive gases and vapors from the inside. Tran site is the ideal material for such service. It is highly corrosion-resist ant -- not only inside and outside, but clear through. Transite Ventilators, made from Transite Pipe, described elsewhere, are designed for use on all buildings where fireproof, fume-proof and weather-proof construction is de sired. They are especially satisfac tory for engine houses, gas and power houses, laboratories, fac tories, etc., where a corrosion-re sisting ventilator is essential. They never need painting and have proved Transit# Ventilator 44 most economical because of their permanence and freedom from maintenance. The material of which they are made has a surface smoother than new and clean metal, and the de?ign of the ventilators provide surface contours which permit the unim peded flow of exhaust air. Transite Ventilators have no ex posed metal parts on either the in terior or exterior surfaces. This is accomplished by the use of Tran site throughout and the protection of bolt heads and nuts by a cement similar to Transite itself. Transite Ventilators are avail able in sizes from 10 to 36 in. Sizes 10 to 24 in. are shipped assembled. Larger sizes are shipped knocked down, but may be readily erected. Johns-Manville SOUND CONTROL OF MECHANICAL EQUIPMENT Fc' *"s cf r-c'=- ' sir-csrsitigning. ana ctns* rr-c-i-vca' Jgnrs-.Vsrvve success a number c: b ~2re''ais. rrs "O'e imccrrant- of which are ae- s:ribed ceicw.

Self-contained units should have the mechanism isolated from its housing, the usual metal panels of which should be lined with an efficient sound-absorbent, such as J-M Air-Acoustic Sheets or Sound Isolation Blankets. Air-Acoustic Sheets are rigid, non-combustible, moistureresistant, sound-absorbent sheets made of rock wool with a suitable binder. They are furnished 24 x 36 in., in thicknesses of *2 and 1 in. J-M Sound Isolation Blankets are composed of *j, 1 or 2-in. thickness of rock wool stitched between sheets of flameproofed muslin, or flame-proofed muslin one side and flameproofed kraft paper the other. Both styles of Sound Isolation Blankets are available in roll form in widths of 22 and 36 in., and in special sizes on order. Mechanical Refrigerators Mechanical refrigerators are usually provided with ade quate vibration isolation for the power unit, but opening# for motor and condenser ventilation necessitate noise-reduction in the machine compartment.

Oil-Burning Equipment For a conversion oil burner connected with an existing heating plant, the most that can be accomplished in noisereduction is to enclose it in a sheet metal housing lined with Air-Acoustic Sheets or with J-M No. 102 Banacoustic Blan ket, made of rock wool felted between 1-in. mesh wire, sup plied 2 x 4 ft. and 2x8 ft., in 1, l1? and 2-in. thicknesses, and in cut pieces on special order. In a self-contained oil burner and boiler, the combustion roar can be lessened by isolating the boiler from the housing and covering the boiler assembly and lining the housing with J-M No. 102 Banacoustic Blankets. Metal Furniture The objectionable noise frequently occurring in panels of metal furniture can be quieted by increasing the stiffness of the panel and applying J-M Pre-Cemented Silento Felt to the interior surface. This is a special, asphalt-saturated felt, approximately 1/16 in. thick, with a factory-applied coating one side, which is rendered adhesive, for application, by using a solvent. In place, the felt will withstand temperatures to 300" F. without bleeding or slipping and may be painted or oven-dned a- re quired.

In large systems, air-conditioning equipment shou'd be lo cated in a separate room which has been sound-isolated and treated with sound-absorbent material, with the mechanical units individually mounted on J-M Vibration Isolation Plat forms (described later). Ducts should be lined with a mate rial which must be fire-proof, highly sound-absorbent, mois ture-resistant and having a surface which will not materially increase friction losses in the duct system. J-M Air-Acoustic Sheets meet these specifications completely. Machine Isolation J-M Vibration Isolation Platforms, individually designe i for the particular condition and location, make possible the allocation of machinery and motor units at points of economic advantage without creating a disturbance in the adjoining parts of the building. These platforms consist of a top, to which the machine is later fastened, secured on tiers of stringers, which are separated and supported by vibration absorbing "chairs," with a fill of loose rock wool placed be tween the stringers and secured by an apron.

Johns-Manmlle Friction Materials are of both flexible and rigid type, to meet every service condition and all de signs of equipment. The flexible styles, which include the various woven linings and the woven and compressed and folded and compressed materials, are readily adaptable to all suet of drums. These linings are suitable for average and high-speed operation, have high frictional value and maintain a relatively constant coefficient of friction through a wide range of temperature. Due to a certain amount of resiliency, the flexible linings readily conform to irregular surfaces and do not require any wearing-in period. The rigid styles, which include J-M Asbesto-Metallic Fric tion Blocks and J-M Moulded Lining, are noted for mechani cal strength, uniformity of friction, smooth, quiet operation and long life in severe, low or average speed service. The wearing-in period is relatively short. Because of their high mechanical strength, they are particularly adaptable to se vere shock service where there is tendency to crush or shear the friction material due to the sudden application of heavy loads. Both flexible and rigid styles possess to an unusual degree the three fundamentals required for a friction material in in dustry--heat resistance, mechanical strength and durability. J-M Woven and Compressed Lining Style No. 900 This new, general utility woven lining for severe sen-ire. i. the most recent advance in the development of a.-be-to- fric tion materials.

It reau..y con forms to various size drums, is strong and adaptable to average speed and shock load conditions. It will re-;-t tem peratures up to 500' F. satisfactorily and its fnctionui value remains within reasonable limits through a wide variation of temperatures. Its rate of wear is unusually low, con-idcrubly below that of other woven or moulded materials.

The co efficient of friction is relatively high and constant through a wide range of temperature. The wear factor is very low. The varied metals in the wire insertion reduce scoring ten dencies to the minimum even when used on steel friction surfaces. J.M Standard Woven Lining Style No. 300 A dense, solid woven lining with brass wire insertion and impregnated with a heat-resisting compound. It is particu larly adaptable to light high speed service where a rela tively high and constant coefficient of friction is required through a wide range of temperature. J-M Standard Oil-Resisting Woven Lining Style No. 304 Has same structure as Style No. 300, but is impregnated with an inorganic compound to resist oil. The inorganic impregnant is not thermally plastic and under heat shows an in crease in frictional value rather than a fade. The lining is somewhat porous, thus giving the oil a chance to dram through the lining as the oil film is broken. J>M Giant Oil-Resisting Woven Lining, Style No. 404 Has same structure as Style No. 400 and is impregnated with an inorganic compound. With the same characteristics as Style No. 304, it is furnished in heavier thicknesses. (Xotr__ Oil-Resisting Linings ire not cirritd in toek, ind ire mide on special order only-) J.M Giant Rotary Woven Lining Style No. 410 Similar in structure to Style No. 400 lining but is im pregnated with a high heat-resisting compound especially suitable for brakes on rotary draw works used in connection with oil well drilling. This lining is rugged, has great re sistance to wear and heat, and maintains a high frictional value with minimum fade, through a wide range of temperature. Smoking and dusting of the lining has been min imized. The incorporation of lead and zinc wire with the brass wire lessens scor ing tendencies and considerably in creases the life of the brake drums. for severe shock service, and. due to the:r high heat-re?i.-:ance. should be used where temperature is a factor. Their coefficients of friction remain remarkably constant throug.n a wide temperature range. Style No. 100 Friction Blocks are designed primarily for use on cast iron friction surfaces. Style No. 120 Blocks are recommended for steel surfaces. J-M Moulded Friction Lining Styles No. 200 and No. 220 These moulded linings are of the rigid class and have prac tically the same composition as the block material, but of !e.-thickness. Although rigid, this material is readily adaptable to wrap bands, either internal or external. Style No. 2'"> Moulded Lining is recommended for cait iron friction out faces: Style No. 220, for cast steel. (Xote--Sketches or accurate dimensions are necessary *hen orJf.t* block materials.) Clutch Facings Facings for both cone and disc clutches can be made from any of the above mentioned materials. Insert blocks can aUo be furnished from J-M Asbesto-Metallie Block material. J-M Rivet Hole Plugs Style No. 1200 J-M Rivet Hole Plugs are used for filling the countersinks in the rivet holes. Style No. 1200 contains graphite and in composition is similar to Style No. 120 Asbesto-Metallie Brake Block. Rivet Hole Plugs are recommended for use with all styles of block and fabric linings operating against both steel and cast iron surfaces. The advantages in their use include: Reduction of scoring tendencies by preventing accumulation of dirt in rivet holes; and an increase of braking surface. J-M Rivet Hole Plugs are shipped in a plastic condition and are packed in air-tight containers. Caution must be taken that the lid of the container is on tight at all times to prevent drying out of the plugs.

Its characteristics make it desirable, however, for many other electrical uses. Transite Korduct was developed by Jokns-Maxville to provide the desirable qualities of a Transite duct in the light est usable wall strength. It is identical with Transite Con duit with the single exception of wall thickness, and the properties affected by such difference. It is not recommended for installation underground without a concrete envelope, nor in exposed locations where considerable mechanical strength is required. In both of these fields, Transite Con duit has proved itself pre-eminently suitable. However, in its own field, as a protected duct, Transite Korduct has no supe rior for'satisfactory service and economy. It will adhere readily to the wall of any type of duct, if it is reasonably dry and clean, and to the lead sheath of cables or to other metals; can be easily removed and completely sal vaged. It is not thermo-plastic and will not slump away from the sides or tops of ducts or cables, yet will permit the ordi nary movement of cables due to changes of temperature. It has very slight tendency to set or harden in service, a tough, dry film merely forming on the surface exposed to the air. It is insoluble in ordinary ground waters and is not affected by gases or condensates usually encountered underground.

Sufficient strength is built into this material to insure sat isfactory shipping, handling, storage and installation in a concrete envelope. It is the ideal material for constructing duct lines where the conventional concrete envelope is used. To a greater degree than any other conduit material on the market today, Transite Konduct combines permanence, in combustibility, smoothness of bore and rapid dissipation of copper heat with economy of installation resulting from light weight and long sections. T ransite Korduct is of distinct advantage where ducts must be provided in concrete structures, such as bridges, tunnels, dams, foundations, retaining walls, floors or any other ma sonry or concrete structure, as well as all underground con ditions where a concrete envelope is essential.

It is employed for switch board panels, controller plates, switch bases, bus bar sup ports and other electrical mountings. Because of its struc ture, it w'ill withstand shock and vibration, is unaffected by sudden temperature changes, such as caused by arcs or flashovers, and will not shrink, crack or buckle under severe serv ice conditions. It is impervious to water, oil, gas and ordinary chemicals. JohnS'Manville Ohmstone There is continually present in open hearth steel mil..' a fine, metallic dust which settles on every piece of appaiatu.-. This dust deposit on panel faces causes an electrical leak be tween parts of opposite polarity which eventually result.- in a carbonized path, if the panel is of any moulded composition. These carbonized paths may, for a time, be removed by sand ing the panel surface, but gradually reach a trouble.-omo depth. Panel surfaces of Asbestos Ebony, as well as all hot or cold-moulded materials used for electrical insulation pur poses, are affected by this condition. J-M Ohmstone has been developed to provide a material immune to such carbonization. It is a non-impregnaied. as bestos-cement sheet that will stand shock and vibration, de signed for use as controller face plate? or rheostat mount? n steel mills and other dust-laden process plants where electri cally conducting dust is present, or for service under n:o:e severe heat conditions, continuous or intermittent, tnan tnose for which J-M Asbestos Ebony is suited. J-M Ohmstone is furnished in stock sheets of the follow ing sizes in 4 to 2-in. thicknesses: 36 x 48 in., 42 x 4b in. and 42 x 96 in. While the natural color of the base material is a deep slate gray, Ohmstone is sprayed before shipment with a non-carbonizing lacquer which gives a non-glaring black surface, the identical lacquer and finish which is used on J-M Asbestos Ebony. Asbestos Ebony bench board at Bureau of Power and Light, Dept, of Public Service, City of Los Angeles, Cal. High dielectric strength, insulation resistance, mechanical strength and durability, although relatively lighter in weight than other materials used for similar purposes, are its prin cipal characteristics. Asbestos Ebony is furnished in sheets 36 x 48 in. in thick nesses from 4 to 4 in. and in sheets 42 x 48 in. and 42 x 96 in. in thicknesses from 4 to 4 im, or finished panels of any size within these limits. Asbestos Ebony control bench and instrument boards t the North Side Pumping Station, Chicago, 111. OHMSTONE CHARACTERISTICS (1) Durability--J-M Ohmstone is a dense, homogeneous, monolithic sheet, not laminated. It will not warp or shrink under normal conditions. Sudden temperature changes, due to arcing between closely mounted apparatus, or Aashover.-, do not result in rupture. The material actually grows strong er and tougher with age. (2) Deaslty aad Hardaai*--Ohmstone has a specific gravity of approximately 2 and weighs approximately 124 lbs. per cu. ft. It has a Brinnell hardness in excess of 20 and does not contain either hard spots or spongy areas. (31 Railrioaca to Sarfaee Are--In its ability to withstand surface arcing without carbonization, Ohmstone surpas.-e? all other synthetic insulating slab materials. (4J Dielectric Straagtk--The dielectric strength of Ohm stone is in excess of 20 v.p.m. or 20,000 v. per inch of thick ness. Where exposed to severe conditions of high humidity and temperature, its dielectric properties are somewhat re duced by surface absorption. (S) Tempere+are Unit*--Ohmstone has a safe working temperature limit of 400* F., but is capable of withstanding, without damage to its electrical properties, occasional heat exposure, flame or arc, far in excess of this limit. (4) Melitare Absorption--'The water absorption of Ohm stone is less than 1% in 48 hours of total immersion. (7) Teoiile aad Cempreislve Strength--Measured both lengthwise and across the sheet, Ohmstone has a modulus of rupture of not less than 4,000 lbs. per sq. in. in 4-m. thick ness, and 2500 lbs. per sq. in. in greater thicknesses. The compressive strength of Ohmstone, in 4-in. thickness is not less than 15,000 lbs. per sq. in., and in greater thicknesses, not less than 10,000 lbs. per sq. in. (!) Waitability--Ohmstone can be worked with ordinary machine tools or, if necessary, with hacksaw and hand drill. Where possible, machining on Ohmstone should be done with abrasive wheels, rather than with steel cutting tools. 50  JOHNS-MAHVILLE ELECTRICAL MATERIALS Expanded Transite For Cell Structures Expanded Transite, one of the latest J-M research develop ments in construction material for the electrical held, is an exceedingly useful and economical material for erecting cell structures, barriers, partitions, compartments or housings for electrical apparatus. It is made of an expanded Transite core faced on both sides with sheets of standard Transite, all bonded under tremendous pressure into one strong slab, rela tively light in weight but with remarkable strength. Low in erected cost, it overcomes the undesirable features incidental to monolithic concrete or masonry and practically eliminates the through metal connections necessary m the Use of natural or precast slabs of other materials. Asbestos Ebony Moulded Asbestos Ebony Moulded is similar to and has the same characteristics as Asbestos Ebony sheets, except that it moulded into special shapes with counterbores, slots or grooves, as desired. Used principally as small panels for switches, starters and meters. Available in thicknesses from U to 1'] in. in square shapes from 6x6 to 20x20 in., and in oblong shapes, to 20x25 in. Eleetrobestos Electrobestos is composed of asbestos fibre and high tem perature clays, cold-moulded to shape, impregnated and heat treated. Widely used for arc or flame barriers and for parts of small ovens, muffles and other apparatus exposed to heat. Well adapted for arc chutes and deflectors, grid buttons, rheo stat or shunt bases, moulded panel shapes and ribbed parts. Electrobestos is not recommended for the mounting or c.rent-camjing parts. Expanded Transit* The dense faces and espanded cs-e achieve great strength with light weight. Expanded Transite, used in combination with Flat Tran site, described elsewhere, offers extraordinary advantages in strength, light weight, facility of fabrication and decided economy as compared with other materials in the erection of complete structures. Expanded Transite is available in standard sheets 48 x 96 in. with an overall thickness of 2 in. (two 4-in. faces with 14-in. expanded core) but greater thickness of core can be supplied on special order. Hundreds of parts such as these can be cheaply moulded from Bectrobestos Eleetrobestos may be safely exposed to steady or intermit tent heat up to 1200" F. Furnished in two types: plain Elec trobestos, which has moderate structural strength but great adaptability to sudden temperature changes, and Elect robestos-X, slightly harder and stronger but not so resistant to temperature change. Usually supplied in moulded pieces, m thicknesses from 4 to 14 in. within size limits of 6x6 in. to 20x25 in., but available in sheet form 30x30 in. in thicknesses of 4, 4, 4 and 1 in.

Cannot Tubereulate Because it is non-metallie, Transite Pipe cannot tuberculate, thus bringing complete freedom from this most trouble some form of internal corrosion and assuring an abunuant supply of clean, rust-free water at all times. Immunity to tuberculation also means that pumping costs w.ll remain permanently low. Corrosion*Resistant Transite Pipe's exceptional resistance to soil corrosion ts due not only to its asbestos-cement composition but al.-o to the dense structure that results from the high pressure under which it is manufactured. In cinder fills and acid and alkali soils that have proved highly corrosive to other types of pipe, Transite is now giving excellent service. Immune to Electrolysis Stray electric currents from high voltage lines or from street railway systems set up a highly destructive action at the point where they leave a pipe line, which condition is in tensified where the soil has a comparatively low dielectric strength. Since Transite Pipe is non-metallic, it is immune to electrolysis under all conditions.

Tests show that Transite Pipe has 13% higher delivery capacity than most other forms of water pipe of same diameter and under same conditions of head and installation. Moreover, this smooth interior surface is maintained in definitely and is not affected by tuberculation or corrosion. Transite Pipe, therefore, provides positive assurance against excessive pumping costs, reduced pressures, cleaning ex pense, shutdowns and costly renewals. This constantly main tained high deliver}- capacity is Transite Pipe's outstanding characteristic. Flexible, Bottle-Tight Joints The special Simplex Coupling used in underground Tran site lines is not only bottle-tight even under severe vibration, but is sufficiently flexible to permit making long sweeps with out the use of special fittings. All but the sharper curves can be made with straight sections of pipe. Consisting of a Tran site sleeve and two rubber rings, Simplex Couplings are easily and quickly assembled, and are largely responsible for the low installation cost of Transite Pipe. Elimination of all water loss by the permanently tight Simplex Couplings reduces operatirg expense, helps to main tain adequate pressures at all times and prevents the breaks in mains so often caused by joint leakage washing away the supporting soil. If the pipe is to be installed above ground, plans should be submitted so that suitable hangers and anchorage may be designed. Immunity to Electrolysis Makes Transite Pipe Advisable in Proximity to Electric Railways Low Installation Costs Despite its many advantages, Transite Pressure Pipe usually costs no more, installed, than any other type of pipe. Its relatively light weight results in appreciably lower hand ling costs--all but the largest sizes can be handled without mechanical equipment. No special working tools are required. The pipe can be cut with a hacksaw or with a well-set wood saw. Service connections can be installed with the same tools now in use, while the line is wet or dry. Valves, also, can be cut into lines with the same equipment now used for other kinds of pipe. But the Simplex Coupling is primarily responsible for the low cost of laying Transite Pipe. The installation is simple and rapid and skilled labor is not necessary. Mechanically assembled, these couplings can be applied in one-third to onehalf the time required for making an ordinary caulked joint. Moreover, the absence of caulking eliminates the need for wide trenches or large bell holes. Further economies are pos sible in trenching because of the flexibility of the coupling and the fact that extreme accuracy as to line or grade is not necessary. An Example of the Flexibility of the Simplex Coupling Also Used for Process Lines Transite Pressure Pipe, either plain or coated, has also been used successfully for handling a number of different types of process liquors. Recommendations in each individual case will be gladly furnished by Johns-Manville. Inquiries should specify the exact service involved.

TRANSITE CLASS S PIPE for Industrial Vents and Stacks corroiivo fumes. Transite Class S Pipe, because of its unusual resistance to internal and external corrosion, is rapidly gaining recogni tion as the outstanding material for venting acid fumes, cor rosive vapors and the products of combustion from various industrial furnace operations. Made of asbestos fibre and cement formed under pressure into a dense, unlaminated structure, Transite Class S Pipe is chemically inert to many of the common industrial ga^es and fumes, and remarkably resistant to the weak acid.- that often cause rapid deterioration of metal vents and stacks. Impregnated and coated pipe is also available for special conditions. Like other J-M Transite asbestos-cement products, Tran site Class S Pipe is strong, weatherproof, inherently perma nent in character, and unaffected by temperatures up to 700* F. Its smooth, grayish-white surface, which will not discolor on exposure to weather, presents a neat appearance, although it may readily be painted, if desired, to match ad jacent walls. The relatively low heat conductivity of Transite Class S Pipe, compared with metal, is of decided advantage in main taining the higher stack temperatures necessary for proper exhaust, and at the same time reduces the fire hazard in frame buildings. The higher stack temperatures which it permits also tend to prevent condensation on the inside of the stack or vent, a desirable feature in connection with cer tain process apparatus.. Economy The corrosion resistance of Transite Class S Pipe makes its use as a vent or stack most economical by eliminating practically all maintenance or replacement. Its relatively light weight, as well as the convenient lengths in which it is 54 JOHNS-MANVILLE TRANSITE CLASS S PIPE for vents and stack. available, not only reduce transportation and handling costs but are also highly desirable when vents are installed in ex isting buildings, as well as in new structures. Suspended lines require only the minimum size of sup ports and impose the least weight, consistent with strength, on existing construction. Stacies may be set on lighter foun dations and have ample strength when properly guyed. Transite Pressure Pipe (see preceding pages) is some times used for the lower sections of stacks. i Pipe Sizes and Fittings Transite Class S Pipe is furnished in sizes up to 5 in. in standard lengths of 10 ft., and in sizes 6 to 36 in. in standard lengths of 13 ft. Standard fittings, made of the same material as the pipe, are available for all pipe sizes. These include sleeve coup lings, which fit over the ends of the pipe or other fittings; 90 and 45 elbows; laterals; tees; reducers; and 90' bends of both 18 and 36-in. radius. Joints are made by filling the joint space between the sleeve coupling and the pipe with a sulphur-base jointing compound or with J-M Flue Pipe Cement. Fittings are joined to the pipe with a sleeve coupling set in cement, similar to the method used in joining pipe sections. r | | Transit* V*nts in the World's Largest Distillery Hiram Walker & Sons.

J-M Moulded Packing Cups J-M Moulded Packing Cups are moulded to the exact size and shape re quired, and give long and efficient service against steam, air, water, oil, etc. They are recommended for use on steam brake cylinders, air hoists, pneu matic chucks, hydraulic presses, valves, etc., and are particularly adapted to s'ow-moving pistons with relatively short travel, steam and air rams for setting clutches and brakes, steam-operated cylinders on vulcamzers, and air cylinders on foundry moulding equipment. Furnished in a variety of shapes, including regular shaped cups, U-shape, with round or square bottom and "Hat" shape. Filler rings of J-M Mogul or J-M Flax Packing supplied for U-shaped cups. Depending on the service, they are made of asbestos, duck, or other fabrics, impregnated with heat and oil-resisting compounds selected to meet the par ticular conditions and temperatures to which they will be subjected. In moulding leather cups to the shape required, internal strains are pro duced which weaken the cup in its flna) form. In the manufacture of J-M Moulded Packing Cups, such heavy distortions are not necessary, and the J-M Cup retains its shape and durability in service. 37 The folded wearing surface of Univer sal accounts for its durability J-M Packing Cups are moulded from exceptionally durable materials JOHNS-MANVILLE PACKINGS AND GASKETS FOR every requirement Service Sheet Style No. 60, !i the on* sheet packing for all conditions.

HU Johns-Maxiville PACKING SERVICE Standardization of all materials used in maintenance is the one most effective method of assuring maximum operating service and greatest return on equipment investment. Only by such means can the quality and uniformity of maintenance ma terials be preserved. The Packing Service Plan, perfected by Johns-Manville. is based on exhaustive study in this field, and will accomplish these objectives. The adoption of this plan has been the direct means of saving many thousands of dollars yearly. Indirectly, it has saved countless hours of uncharged time and avoided great quantities of un allocated trouble. The many advantages to be derived have been demonstrated re peatedly and under widely varying conditions. In every case where it is employed, Johns-Manville Packing Service reduces the capital tied up in packing stocks, minimizes mistakes in ordering, materially reduces handling and storage costs and provides assurance that the right packing will always be available. The first step in the J-M Packing Service Plan is a detailed survey of the individ ual packing requirements, made by J-M engineers. Unnecessary duplications are eliminated and improper applications are corrected. When proper styles of packing have been specified, a chart of packing applications is compiled showing minimum types and sizes. When the J-M Plan is installed it is recommended that costs be figured for the previous year for later comparison. The plant engineer is requested to keep a pack ing service record showing accurately the materials used and when repacking takes place. If the record sheet indicates some item is not giving proper service, an imme diate investigation is made, so that corrective measures can be taken. Only a minimum reserve stock of packing need be maintained because of the J-M Distributor Service which is operated in conjunction with the J-M Plan. The J-M Distributor receives a copy of the packing application chart and immediately stocks the exact styles and sizes of packing required. This makes replacements quickly available. Of first importance are the right packings for all applications. The J-M line of packings has proved its dependability and economy for all types of industrial service. The other essentials are a minimum number of styles and sizes and immediate dis tributor service. These, combined with a simple record method and an efficient system of ordering and replacing, complete this J-M perfect packing service. Tho minimum number of different styles end materials, yet the right packing for any equipment and every service Security on old or now equipment, resulting from definite recommen dations and closely controlled packing standards Over 60 yean af manufacturing and field eiperience are bihltid every J-M Pacfclng 59 OTHER JOHNS-MANVILLE PRODUCTS In addition to the Industrial Construction and Main tenance Materials described in this catalog, Johns-Manville aiso manufactures a number of other products, some of which are used extensively in Industry while others find their principal application in hemes and general building con struction. These products are described very briefly below. In each case complete information Is available in special literature which will be gladly furnished on request. J-M Acoustical Treatment and Sound Control Johns-Manville materials and methods for Sound Control of Mechanical Equipment, which were discussed on page 45, represent but one phase of J-M pioneering in the science of acoustical treatment and sound control. In the Johns-Manville Acoustical Laboratory have been developed a wide variety of sound-absorbing materials de signed to prevent faulty hearing conditions in auditoriums, churches, etc., and to keep noise at an undisturbing level in restaurants, offices, hospitals, and similar locations. Still another J-M contribution to Sound Control--the J-M System of Sound Isolation--is an effective means of treating build ings or individual rooms to prevent disturbance from outside sound. All of these materials, as well as anti-vibration ma chinery platforms, are described in a complete engineering brochure, "Johns-Manville Sound Control," DS Series 250. J-M .Underground Pipe Protection The life of many thousands of miles of underground pipe lines has been materially lengthened by protecting them against corrosion with a wrapping of J-M Asbestos Pipe Line Felt over a bituminous coating. The asbestos felt is strong, providing high resistance to soil stress and protecting the bitumen coating from abrasion. It is inorganic and highly resistant to soil chemicals, water or soil bacteria. JohnsManville also supplies machines for wrapping pipe either in the pipe yard or in the field. For complete information, ask for "Johns-Manville Service to the Oil Industry." J-M Asbestos Textiles and Clothing A full line of asbestos cloth and clothing is furnished by Johns-Manville, as well as braided asbestos tubing and asbestos listing. Fibre, roving and yarn of many different grades are also available. Full details will be furnished on request. Celite Filter Aids Celite Filter Aids have been used for more than 20 years for the clarification of sugars, chemicals, oils, fruit juices, varnish and a wide variety of other products. These materials --Hyflo Super-Cel, Standard Super-Cel and Filter-Cel--are pure diatomaceous silica powders which, when mixed with the liquid being filtered and pumped through the filter press, increase flow rate and press capacity, lower operating costs and assure filtrates that are clear and brilliant. For complete information, ask for DS Series No. 450. Celite Mineral Fillers Celite Mineral Fillers, prepared from an especially pu 1,form of diatomaceous silica, are made in many different grades to meet virtually every requirement of weight, poros ity, abrasiveness, particle size and physical structure. They are used as inert extenders in many products and as the bare-for a wide variety of polishes and cleansers. For complete general data on Celite Mineral Fillers, ask for DS Sene.- No. 470; for information on the use of Celite in Paint, ask fo Brochure FA-10A. Celite For Concrete Celite for Concrete, a special grade of diatomaceous si'icr.. is used in Portland cement concrete to increase the workabil ity of the mix and to improve uniformity, strength, watcitightness and appearance of the final concrete. It i- au,i. i at the rate of from 2 to 6 lbs. per bag of cement, depending on the mix. Full details in Brochure CC-1A. Its use in mortarand plasters is described in Brochure CC-4A.

Their light weight and high insulating value make pos sible thinner furnace walls, improved efficiency and lower operating costs. Furnaces can be brought up to operating temperatures with unusual speed, resulting in increased production. Each type of J-M Insulating Fire Brick has the correct balance of thermal and physical properties for its rec ommended service. All six types offer light weight, low conductivity and high structural strength. JM-3000 Insulating Fire Brick, the newest of the six types, provides long-life insulation at a full 3000F, in back-up or direct exposure service. Molded from specially selected, high quality kaolin clays plus alumina, JM-3000 Insulating Fire Brick raises to a new high point the tem perature for which such a product can safely be recom mended.

Made of diatomaceout silica, a material composed of million* of microscopic cells that offer maximum resist* ance to heat flow, Sd-O-Cel Insulating Brick are particu larly useful where high loading characteristics are re quired. Sil-O-Cel Insulating Brick are furnished in three types for use as back-up insulation behind refractory fire brick linings or behind insulating fire brick linings. The new Sil-O-Cel 16L brick, an improved replacement for the former Sil-O-Cel Natural Brick, may be used for exposed as well as back-up service. Used as back-up insulation, Sil-O-Cel Insulating Brick make it possible to reduce the necessary thickness of the exposed refractory as much as one-third. This results in considerable saving in furnace wall construction for all types of high temperature equipment.

SIL-O-CEL* C-3 AGGREGATE FOR MAKING INSULATING CONCRETE For service to 18OOF Insulating concrete made with Sil-O-Cel C-3 Aggregate can be cast into any shape desired. This makes it possible to utilize insulation where it had been impossible pre viously due to structural reasons. Insulating concrete made with Sil-O-Cel C-3 Aggregate may be used in the construction of core, japanning and enameling ovens, foundations and bases of neated equipment, furnace doors and many special shapes such as baffles, dampers, etc. It is over three times as effective as fire brick in prevent- -- ing heat penetration. Suitable reinforcing, such as would be used in ordinary concrete, and provision for expansion joints must be provided as with any other monolithic ma terial. About 28 lb of C-3 Aggregate needed per cu ft when rammed into place and dried. Mixture sets up into strong, durable insulating concrete weighing about 60.1b per cu ft and with a crushing strength of about 1,000 psi (72 tons per sq ft). Maybe used where sub jected to direct heat as high as 1800F. .* - t -- " Sil-O-Cel C-3 Aggregate comes in 50-lb bags.

It provides an air tight "blanket" over the entire boiler setting. Its ad hesive and ductile qualities keep the coating air-tight, and imperfect combustion due to air leakage through the setting is prevented. Aertite also checks the escape DR BOILER WALLS to 25 OF R ESCAPE OF FURNACE GASES OR DUST of furnace gases or dust, and can be used in other loca tions for miscellaneous sealing against the effects of dampness, air and moisture. Aertite Coating is fur nished in 25, 50. 150. 300 and 500 lb containers. For a H in. thick coating, from 50 to 80 lb per 100 sq ft of surface area will be required.
