THE SOURCE OF MANY UTILITIES Inherent in Gypsum, and reflected in all of its products are an array of utilities that is rarely found in a single substance. Most of these utilities have a direct bearing on the econom ics of construction. Some of these assets are inherent; a few have been built in by research and experi ence. In Gypsum we have a hydraulic cement: !. Which is plastic -- may be cast or trow eled to produce any form. 12. Which contains no alkalies to saponify the oil in paints. Which may be success fully painted with Texolite as soon as it has set. . 13. Which is essentially light in weight -- puts no excessive burden on supporting framework. 14. Which has possessed these qualities for centuries under constant test in build ings since the Pyramids were built. 2. Which possesses a controllable set -- from one minute to ''hours." 3. Which does not shrink when it sets, but actually expands slightly to fill areas and molds. 4. Whose strength, after setting, is con trollable within wide limits -- up to 1 2,000 lbs. per square inch in compression. 5. Which is a useful heat insulator. 6. Which not only does not burn nor sup port combustion, but provides an unsur passed fireproofing agent possessing many exclusive advantages. 7. Which supplies no food for vermin or bacteria. 8. Which sets at the predetermined time without need for substances or gases out side of itself to cause set -- which requires no aging or curing period. 9. Which, when set, holds nails well. 10. Which can be left in its natural mar ble-like white state, or can be integrally colored, textured, painted or papered, by any known method. 11. Which bonds to itself, and to any type of lath used for plastering -- practically monolithic on Rocklath.' RESEARCH AND CONTROL With its production predicated on the maxi mum in quality and leadership in innovations and betterment, the company long ago recog nized the value of directed research which could increasingly utilize the inherent prep erties of Gypsum. The Building Materials Research Labora tory of the United States Gypsum Company, long a feature of the production program, was consolidated and enlarged in Chicago in 1927. It is housed in a special building providing over 26,000 square feet of labora tories and staffed by 90 technicians and scien tists. At this laboratory there is a constant search for better ways of doing those things the company already does well. There is di rected research leading toward the invention of new methods of solving building problems more economically, with constructions struc turally better, or both. Here, likewise, the possibilities of new raw materials are inves tigated and control over the adhesion to the specifications of the laboratory for the production of every company product is exercised. Construction innovations, developed at the laboratories from Gypsum, utilizing these time tested structural assets, are likewise time-tested, and though new, find ready acceptance. united states gypsum company tV O cIO MATERIAL ASSEMBLIES INTERIOR PARTITION ASSEMBLIES Wood Frame Buildings, Bearing or Non-Bear ing, and Fireproof Assemblies i 6 to 9 CEILING ASSEMBLIES Including Fireproof Constructions EXTERIOR WALL ASSEMBLIES Inner and Outer face.

Bond perfectly with gypsum plaster. PLAIN ROCKLATH Rocklath* does not burn or readily transmit high temperatures and when plcsrered with gypsum piasters is fireproof. It contoms noth ing to disintegrate or corrode -- no pitch, resin or gum to stain the plaster. The uniform suction of Rccklcth prevents plaster from slipping during application Gnd insures a uniform bond. U. S. Bureau cf Standards tests show that an 864 lbs. per sq. ft. pull was required to separate plaster from gypsum lath--a safety factor of 144. Rocklath is easily erected. A bundle of boards (32 sq. ft.) is easily earned by one man. There are no rough edges or splinters. One piece covers the same area as 9 wood loth and requires half the ncils. Bcords score and cut without waste. It is not necessary to wet Rocklath before plastering. Rocklath keeps the moisture of fresh plaster from the freme, which prevents swelling of weed members. Walls and ceilings dry quickly. Wells of Rccklcth and gypsum plaster cost less than metal icth and plaster, end little, if any, more than wood lath and piaster.

Because USG Trussteel Studs provide a rigic support for the metal plaster base, plastering is os easy as with the usual meto! lath job. The type of lath to be used de pends upon the stud spoemg. STRENGTH TESTS Results of tests conducted by the Raymond G. Osborne Laboratories, Los Angeles, during November 1937 proved that USG Trussteel Studs had more than adequate strength for building construction practices and were accordingly granted approval for use under the Pacific Coast Uniform Building Code requirements. Tests conducted by the USG Laboratories in December 1939 indicated USG Trussteel Studs to be far stronger than punched channel studs at the foilure point, and c negligible difference at the first plaster crack point. SIZES USG Trussteel Studs ore mode in lengths from 7 ft. to 20 ft., inclusive, in increments of 3 inches. Lengths of from 14 to 20 ft are supplied in two sections, complete with splicing Mature. These are the stock or "fixed" lengths. The adjustable feature on each of these lengths permits adjustment to 4 inches over the stock length. Widths are 2, 3, B V4, 4 and 6 in.

Buildings can be decorated and oc cupied quickly. Fireproof Cypsum plasters provide lire protection at no additional cost. Applicable Work with equal facility on any type of lathing material. Plasticity and slip ease the plasterer's Job. Adaptable to Decoration Cypsum plasters arc adaptable to decoration with any mjterhl ordinarily used on plastered surfaces. Uniform Laboratory control insures that plasters manuffactured at all USC mills will produce like results. Comply with Standardi All USC plasters comply with standards of the American Society for Testing Materials. Federal Departments and construction agencies. GYPSUM FIREPROOF Gypsum 15 o sedimentary rock, technically, "hydrous calcium sulphate." When found in proper purity it is quarried or mined, crushed, ground end calcined (partially dehydrated) to produce o cement. Its time of set is confrolloble between wide limits through the use of chemical accelerators and retarders. Special processes developed through long research have created a series of wall plasters mode of gypsum which will consistently answer every building need; available in like quality everywhere. Gypsum plaster sanded according to standard specifications m standard thickness, provides o full hour fire rating for wood stud partitions when applied on gypsum Rocklath (perforated) or metal loth. Gypsum plostering has long served os a real fire protection for frame buildings. FINISHING MATERIALS GYPSITE Gypsite is an eroded form of gypsum, containing small amounts of clay or similar erosion products. Quarried like gypsum, it is the source of the "Gypsite" or "Dark" plasters of the Southwest. Bose coots and finishes mode of Gypsite vary in color from red dish yellow through pink shodes to almost white. Gypsite plasters are fully acceptable for the best work but carry slightly less sond for equal strength ond hardness. Finishing materials are available "ready-mixed" or finishing lime ond gcugmg plaster may be job mixed to produce any type cf finish from the hard, smooth trowel finish through sand float fin ishes m various degrees of surface sanding to the deep texture surfaces in white or color obtainable with Oriental Interior Finishes. FINISHING LIMES PLASTERING Good plastering involves good lath ond three coats of properly specified plaster. The scratch or first coat is followed by the brown or second--straightening coat--which brings the face of the wall or ceiling to its final position. The brown coot may carry increased sand--3 parts to 1 I by weight) without loss of strength or fireproofness. The final finish coat is hard, dense, thin and self-decorating, or can be decorated with Texolite (see page seventv-two) when dry without danger of difficulty from damp ness or lime in the finish ^oat. Finishing limes are manufactured in three types and from two sources of raw materials. Raw or quicklime usually requires ccreful and longer soaking to secure complete hydration. Hydrated lime has been fully or partially hydrated before shipment--it soaks quickly into a useful putty. Pressure hydration (a new process l permits practically complete hydration of all of the oxides in limes containing magnesium. In older hydration meth ods, the magnesium oxide did not hydrate during the mill hydra tion process but hydrated slowly on the job, occasionally producing difficulty due to the expansion which followed. With USG pressure hydration, over 92% of the lime is fully hydreted. Finishing limes are produced both from high calcium deposits of limesfone, containing at least 93% of calcium carbonate, and from dolomite limestone, containing additions of not over 45 % of magnesium carbonate, UNITED STATES GYPSUM COMPANY I FINISHING LIMES (Continued) COVERAGE The choice between quicklime and hydrated lime, made from dolomite or high calcium stone, should be governed Icrgely by the local practices of plasterers in the vicinity in which a building is to be built. All types will produce acceptcble finishes in the hands of properly experienced mechanics. GAUGING PLASTERS The covering capacity of USG plasters is as great for each type of material as it is possible to obtain. The area of wall which can be produced by a given quantity of plaster vones with the following factors: The mechanic, the thickness of the wall, the kind ond trueness of the surface to be plastered, the sue and number of keys in the lath, the quality of the sand, the amount of sand used, etc. The covering capacities given in the table for each variety of plaster are based on average conditions and are quite conservative. Gauging Plasters are made solely for odmixture to lime putty to secure hard trowel finishes. They lend greater strength and density to finish plaster and are ground to the correct particle size for quick assimilation and even dispersion through the putty that must be accomplished if a prime finish is to result. Available in white (at slightly higher prices in some locali ties' or light shades local to producing mill in either quick set or slow set types. KEENE'S CEMENT Keene's Cement is a very hard, slow setting, dense cement, mode from gypsum rock of great purity ond whiteness, found ot only a few places in the United States. Unlike other hydraulic cements. Keene's Cement may be retempered. Its slow setting property permits scoring the plaster finish to creote masonry joints m the surface. Piaster finishes made with fine Keene's Cement are stone-like in character and GDpearance. They may be polished to a gloss as high as that given marble. Keene's Cement is on excellent moterial to use in the production of colored interior finishes and for imi tations of Travertine end Caenstone. By variations in grind ing and mill treatment it has been possible to produce several special types of Keene's Cement, particularly adopted for special purposes. ARIDIZE* MOULDING PLASTER Aridize Moulding Plaster may be used for both "run" moulds or cast ornament. Particularly smooth working ond of uni form setting quolity, Aridize Moulding Plaster is ground much finer than other similar products, assuring more thorough solution and finer surface of the finished work. Its cooler working and slower setting qualities account for low expan sion and the absence of warped moulds. Slow generation of heat in setting protects gelatin or glue moulds from quick deterioration. Slow setting gives time for blending and work ing out entrapped air bubbles and for working the plaster into angles and corners of moulds. Even when green, moulds of Aridize have great strength. Breakage in handling and manipulation in the moulding and costing stages is reduced. Aridize Moulding Plcster is sold under the following trade names in different localities: Red Top (local color'. Red Top No 1 (white!, Red Top Kings Diamond (white!, Golden Seol i white).

Its use speeds constructions, maintains the high quality of fire protection of Pyrobar Gypsum Tile (see pages 54 and 55) and should be the mortar required m every specification involving the use of clay or gypsum partitions and fireproofing.

GENERAL NOTES ON PLASTERING To obtain the best results it is essential that all operations con nected with plastering and lathing shall be in accordance with the best practices of the industry. Attention is specifically directed to the following: Tools used for mixing and applying plaster must be kept clean. Dirty tools accelerate the "set" of plaster. Woter must be cleon. Water containing salt or alum, or water m which tools hove been washed, accelerates the "set." Woter from stagnant pools and wells frequently contains organic or vegetable matter which may retard the "set." Sond is not a cementitious material. It is. however, a very important ingredient. Extreme care must be exercised in its selection. Fine sand should never be used. The finer the sand the larger the total surface area in relation to the volume of particles ond the greater the amount of gypsum required to coat each gram Sand used in plaster must be well graded from fine tc coarse. Oversandmg weokens the plaster proportionately, ond usually accelerates the "set." Fine sand, hovmg rounded particles, uniform in size (fre quently called "quicksand") must not be used. It can be eosily detected since it settles in the bottom of the mixing box, gives the mixture a watery appearance and causes it to work "short," and produces a weak plaster. In the accompanying specifications for gypsum plastering all formulas for plaster mixes are based on the use of sond con forming to the requirements of the Standard Specifications for Sand for Use in Plaster (A.S.T.M. Designation: C35-39) of the American Society for Testing Materials.1 Drying--A portion of the water used for mixing plaster is necessory for the chemical reaction which sets and hardens plaster. Therefore, plaster must not be permitted to dry out before setting has token place. It must be protected from blasts of wind ond from drying unevenly or too rapidly. If glazed sash are not in place, ond it is necessary to enclose the building, exterior openings of the building shall be screened with cheese cloth, or similar material. In cold, damp, or rainy weather, properly regulated heat must be provided, but precautions must be taken against too rapid drying before set has occurred. As soon as the plaster has set, free circulation of air shall be pro vided to avoid sweat-outs. After the plaster has set, heating shall be continued to insure as rapid drying as passible. Plaster must not be allowed to freeze before it has set. Alternate freezing and thawing must be avoided. Bituminous Coatings--Because bituminous compounds do not provide ideal bases for plaster, the applying of plaster to ma sonry or concrete which has been coated with such compounds should be discouraged. Plastering on Monolithic Concrete Surfaces, regardless of the type of plaster used, requires care and the taking of certain precautionary measures. The use of dressed i smooth lumber, metal, ond plywood forms, oiling or greasing of same, and the vibrating of concrete produces concrete surfaces which are so smooth that mechanical bond necessary for plaster is absent. The adhesion of plaster to concrete depends largely upon the condition of the concrete surfaces at the time of application of the plaster, type of plaster used, and workmanship employed. Concrete surfaces which are to be plastered should be rough. The desired character of surface may be procured by using rough forms which hove not been oiled or greased, or by hacking or bush-hommering the surface to be plastered after the forms are removed ond before the concrete has become too hard, or by applying a dash-coot of portland-cement grout. 1 See Note Poge 39.

Only water is added on the job. ORIENTAL* EXTERIOR STUCCO ADVANTAGES Streoking, due to insufficient mixing of stucco "on the job" is eliminated with USG factory-mixed stuccos. With job mixing, proportions of materials used are likely to vary, producing stuccos of varying qualities. With foctory mixing quality is olways standard. ' Uniformity of color in successive batches is obtained so that joinings between separate applications will not show if proper precautions are taken. USG Oriental Stucco is water-resistive and its waterresistance and strength increase with age. The mineral colors do not fade, nor are they affected by the other ingredients used to make stucco a plostic material. Setting time is slow enough to provide a sufficient inter val between application and set to permit smooth-troweled, stippled, sponged, rough cost, period textures or spatter finishes. Since only water is added, time is saved on the job. COLONIAL Light stippletroweled slightly to produce highlights COVERING CAPACITY Base Coaf--The approximate covering capacity of one ton of Oriental Extenor Stucco Base Coat (scratch and brown coats) under overage conditions, is as follows: Plastering Brick and Surface cloy tile Metal lath Wire fabric Cement ond Concrete cinder tile Sa yd. per ton 20to25 . 25 to 30 22 to 23 - 20to22 20 to 25 OAK BARK Vertical brush ing -- light dash of sama color--doshed spots flattened with trowol Finish Coat--One ton of Oriental Exterior Stucco, Va in. thick, will cover from 150 to 200 sq. yds., depending on the texture selected. APPLICATION Oriental Exterior Stucco should be applied over USG Ex panded Metol Stuccomesh, weighing not less than 1.8 lbs. per sq. yd., or USG Self-Furring Diamond Mesh Metal Lath, weighing not less than 3.4 lbs. per sq. yd. MODERN CALIFORNIAN Stippled-- medium heavy dosh--flattonad vigor ously with trowel ORIENTAL INTERIOR FINISH Orientol Interior Finish supplies similar beauty in texture and color for interior plastered surfaces. It moy be floated to various degrees of coarseness by varying the float used. It may be textured with stippling brushes, sponges, brooms and other tools to resemble the illustra tions of Textured Oriental Stucco on this page. Spots of Oriental Interior Finish in contrasting color moy be ap plied at random to the wall and blended into the surface with float or wadded burlap.

THE FIREPROOF WALLBOARD DESCRIPTION AND TYPES What It Is--Sheetrock, composed of a rugged core of gypsum en closed in rough paper, js an all-purpose, fireproof wallboard. When appliea, it produces a fimshea surface reacy ro be decorated i for predecorated types, see pages fifty and fifty-one). Used in new buildings, nailed directly to framework, for all walls and ceilings; and in existing structures for remodeling. The ' j-in. thickness is ideal for application over old plaster surfaces. The joints between boards may be left frankly visible, may be covered with batten strips or mouldings of various sorts, or may be completely concealed. Sheetrock will take any form of deco ration including wallpaper. Sheetrock produces a strong, rugged wall or ceiling which is completely incombustible. A standard constructon material, accepted and approved as such for over 20 years. Recesied-Edge Sheetrock--Recessed-Edge* Sheetrock used with Perf-A-Tape* provides an improved permanent reinforcement at the joint between boards and simultaneously conceals the joint. Because of the "channel" prepared by the recessed edge, PerfA-Tape reinforcement and the cement used when finished are flush with the face of the board, eliminating any bulge or shadow to indicate the presence of the joint. The strength of the joint is as great as that of the board and, consequently, it will permit horizontal application of the boards (the long edge parallel to the floor) in walls and similar appli cation across the |Oists in ceilings without the necessity for, or expense of, headers. Such horizontal construction effects many economies and as well produces a stronger construction more resistant to building frame movement. Recessed-Edge Sheetrock may also be applied vertically (long edges parallel to supports). Insulating Sheetrock--Any type of Sheetrock, decorated or plain, may be obtained with a sheet of bright metal foil attached to its back surface, providing at once both an insula tion \aiue against heat loss or entrance equivalent to that of ',2-m. fiber insulation board, and a highly efficient vapor bar rier. The coefficent of heat conductivity is approximately .66 E.t.u.'s per hour, per square foot, per degree difference in tem perature. Finishes--Regular Sheetrock is furnished in a cream, almost white finish for the exposed face. There is also available Wood Grained Sheetrock in Walnut, Knotty Pine and Bleached Ma hogany which are described and pictured on pages fifty and fiftyone and Sheetrock Tile Board on page fifty-three. Recessed Idee offers a wall* board construe* Hon that makas possible strong* or. smoother, and better*look* ing wallboard jobs. When sheets are nailed in place, recessed edges form a channel at each loint. Channel is tilled with special ce*> ment, quicklv and easily ap* plied.

Pyrobar Par tition T lie are machine-niade and moulded extremely accurately. All are scored to receive plaster except when specially ordered, when smooth surfaced tile can be fur nished. for sizes, weights, etc., see table at top of opposite page. ADVANTAGES 1. Fireproof a. Gypsum is incombustible. Adds no fuel to flames. b. Gypsum cannot pass high temperatures ; hence : 1. Keeps heat from heat vulnerable steel. 2. Confines ignition temperatures to room of their origin, effectively restraining the growth of a building fire. c. Gypsum constructions will not expand under fire exposure suf ficiently to wreck themselves or dislocate fire-weakened steel. Since they expand not through some 1800c but through the low gradient from room temperature to 212 regardless of the intensity of the fire. d. The fire resistance ratings of gypsum constructions have been established by numerous laboratory tests and proved by observed behavior in many fires; their high degree of protection is a matter of record. e. Under fire exposure, gypsum calcines Closes its water of crys tallization) progressively from the exposed face. The calcined por tion, soft, spongy and heat insulative, clings to the face further retarding the progress of calcination. Regardless of the fire tem perature, the temperature in a protected room or of protected steel can not exceed 212 F. until the gypsum is calcined clear through. The rate of calcination is very slow. A 3-in. Pyrobar partition pro tects for 2 hours against standard test exposures, a 4-in. partition for 4 hours. 2. Less Weight Clay tile, as used for fireproofing, weighs from 229c more for 2-in. split furring to 509c more for the much used 3-in. hollow non-bearing tile than Pyrobar Gypsum Tile (figures calculated from data in A.S.T.M. specifications t'or both materials). The stone concrete protection for an I-beam whose 6-in. flange is 8 in. below the structural floor it supports weighs 83.4 lhs. per running foot of beam. Pyrobar beam and girder protection tor the same beam weighs but 26 lbs. per running foot. The concrete pro tection weighs 2279c more. 3. Large Economical Units The large economical units, laid in Blockset Cement (see page thirty-one), use less mortar as they have fewer joints, require less labor, speed completion. Inherently economic, these materials supply maximum utility. 4. Easily Cut and Fitted Pyrobar Gypsum Tile are quickly cut with a saw to fit any con dition. They do not shatter when cut. eliminating breakage waste. Pipe and conduit chases are accurately cut. 5. Excellent Plaster Base Pyrobar Gypsum Tile are cast in accurately dimensioned straight true molds. They do not warp, twist or shrink when setting. There fore, Pyrobar Tile are true to dimension, make straight walls with plane faces, saving plaster. The bond between gypsum plaster and Pyrobar Tile has a factor of safety of 173. 6. Fit All Beam and Girder Shapes Pyrobar Beam and Girder Tile Pyrobar Beam and Girder Tile are designed to accommodate all standard steel shapes as rolled or built-up girders with a minimum number of tile shapes, reducing the number of fireproofing shapes on the job, cutting costs and speeding completion. For beam and girder protection, the flange of the beam or girder is protected by the most suitable of the four types shotvn above and detailed on the opposite page; the toebs are covered ivith Pyrobar Partition Tile supported as shotvn in the details. For column protection, Pyrobar Gypsum Partition Tile, of proper thickness, are laid up around col umn in log-cabin fashion; all.short pieces may be built in. 7. Availability Pyrobar Gypsum Partition, Furring and Fireproofing Tile are available in like excellence, made to the same standards, presenting identical usefulness and fire protection, from each of a string of manufacturing mills stretched from coast to coast. Architects speci fying Pyrobar can ignore design requirements imposed by iocal aggregates, hard or soft burned tile, etc. ___ *Rcg.

If thoroughly burned brick, tile, hard dense stone or concrete are used and construction is correct, excessive water penetration can occur only at joints. Lime mortars are the most effective means of providing watertight joints. Hirsh Brick Mortar Without Lime Does Not Fill Spices in Will Advantages of Lime in Masonry Mortar Plasticity--Lime is the most plastic cementing material. Building units must be thoroughly and uniformly bedded and joints well-filled to assure leakless masonry. The more plastic the mortar, the greater the chances of uniform distribution. Bonding Power--Lime bearing mortars adhere to the build ing units uniformly at all points and have sufficient elasticity to adjust themselves to varying stresses. They do not tear loose from the building units. Low Volume Change--Lime is the only cementitious mate rial having negligible volume change after hardening. It; high water retaining capacity prevents compacting, the important cause of leakage through vertical joints. Extensibility--This quality determines extent to which mortar will stretch before it fails in tension. Lime mortars and mortars containing lime have ample extensibility. Strength--Strength in mortar does not necessarily indicate durability. Test data indicate that mortar mixes containing lime produce mortars of ample strength. Examples of enduring qualities of masonry laid in lime are found in old structures in Europe and America. Brick Mortir with Lime Produces Watertight, Durable Walls Lime in Concrete Hydrated lime is used as an admixture in concrete for its qualities of water-tightening, lubricating and physical stabiliza tion. It makes concrete watertight by increasing workability; re ducing honeycombing, stone pockets, etc.; filling forms, pre venting segregation, and reducing the relative amount of water required. High Calcium and Dolomitic Limes Quicklime or hydrated lime can be produced from either high calcium limestone or dolomite (high magnesium lime stone). In building construction, the physical rather than the chemical composition of lime is important. Therefore, either calcium or magnesium lime may be selected as the physical properties are the same.

They bond well with standard waterproof roof coverings; are heat insulative or may be readily insulated. They should contain nothing to cause deleterious effects on any material they contact; be proof against rot; decay, the common fac tory gases and many of the unusual ones. Their under surfaces should reflect light well; be of good appearance and be capable of quick economical renovation with factory paints such as Texolite.* USG has solved roof and floor problems competitively and successfully, for over 25 years. Millions of square feet of these roofs and floors are in use. They are regularly specified by prominent architectural offices. Their advantages are briefly established on this page. On the opposite page the con structions are tabulated and compared for quick selection. On later pages, each type is described, detailed and fully illustrated. LIGHT WEIGHT HEAT INSULATING Precast gypsum constructions are light in weight because gypsum is inherently light. The weight cf "poured-in-place" construetion is further reduced by the use of light weight aggregates. Gypsum, unlike most fireproofing materials, is an excellent heat insulator. Gypsum roofs are generally amply heat insulative to prevent condensation under any normal building exposure ADAPTABLE Reccily cost m piece or cut to fit (when precast), practically any strucfurcl requirements may be met. LIGHT REFLECTIVE The smooth, white, closely knit gypsum surfaces are well known cs efficient reflectors of light; when soiled by time, both color and reflective ability ore easily restored with USG Texolite.
