Offices In All Large Cities Home Insulation Applying Spinlex baits in n*to home For Existing Homes and Buildings: J-M Spintex "Blown" Home Insulation J-M Spintex Home Insulation is nodu lated mineral wool which is blown pneu matically into the spaces between studs in outer walls and between roof rafters or attic floor joists. Insulation thickness in walls corresponds to stud depth, approximately in. The uni form fill assures maximum thermal effi ciency. This type of insulation is sold and installed only by carefully selected experienced and officially franchised J-M Blown Home Insulation Contrac tors.

For New Construction: Spintex Batts and Blankets Johns-Manville Spintex Batts and Blankets are made of spun rock wool. Instead of short, coarse fibers, this J-M spinning process produces long, fine fibers which make better, more firmly felted batts and blankets that are stronger, lighter in weight, more resil ient, and have greater uniformity throughout. They are rotproof, fireproof, and assure the homeowner of maximum year-round comfort, protection and winter fuel savings. SPINTEX BATTS are strong and sturdy. They will not break down under rough handling but hold their factory-made shape and uniform thickness . . . will not crumble or fray when cut to fit irregular spaces. Each batt has a vapor seal back ing to protect against the passage of abnormal humidity and a tacking flange for ease of installation. Spintex Batts are furnished Ful-Thik and Semi-Thik. Ful-Thik Batts have an average thickness of 3)4 in.; Semi-Thik, an average thickness of 2 in. Both types are available in sixes 15 x 24, 15 x 48, 19 x 24, 19 x 48, 23 x 24 and 23 x 48 inches. SPINTEX BLANKETS, made of the same firmly-felted long fiber spun rock wool, are fully enclosed in a permeable wrapping with an approved vapor seal backing and a tacking flange. Thick Blankets, approximately 3 in. in thickness, are furnished in sizes 15 in. x 48 in. and 23 in. x 48 in.; Medium Blankets, approximately 2 in. thick, in sizes 15 in. x 64 ft, 23 in. x 64 ft, 15 in. x 8 ft and 23 in. x 8 ft; and Service Blankets, approximately 1)4 in. thick, in sizes 15 in. x 8 ft and 23 in. x 8 ft. Airacoustic Sheets for lining Air-Conditioning Ducts J-M Airacoustic Sheets provide a firesafe, sound-absorbing material de veloped for use in ventilating ducts. Since they absorb a large percentage of the sound that strikes them, they pro vide a highly effective means of reducing undesirable duct noises. Composed of rock wool and a suitable binder, Aira coustic Sheets are available in size 24 in. x 36 in., and in thicknesses of )4 in and 1 in. Spintex Duct Insulations Spintex Duct Insulations are incom bustible . . . provide high insulating effi ciency and long service life. Their low installed cost is the result of JohnsManville's long experience in developing proper methods of application. They are furnished as blankets and semi-rigid boards. The densities range from 2 to over 6 lb per cu ft, providing flexible and stiff materials for round or rectangular scientifically correct insulations and ducts. 1670 Johns-Manville Pipe and Boi J-M FIBROCEL Insulation Insulations J-M 85% MAGNESIA J-M Fibrocel Pipe Insulation is a molded The high insulating value and per silica insulation developed by Johns- manence of J-M 85% Magnesia Block Manville for use on hot, cold and chilled and Pipe Insulation have been proved water lines, low pressure steam pipes,, over many decades of satisfactory, and dual service heating and cooling sys trouble-free service.
