JM Built-Up Roofing Systems,Still the Best of the Tried and True.Built-Up Roofing SystemsConventional bituminous built-up roofing(BUR) membranes have been usedeffectively for more than 100 years andare still popular today. With BUR roofingsystems, the waterproof membrane isfield fabricated with layers of bitumenalternating with plies of reinforcing felts.JM manufactures a complete line of fiberglass felts, including base, ply and mineralsurfaced cap sheets.EPA and California Title 24 standards,offering additional savings on cooling costs. Variety of Colors – many of our durablecap sheets are available in several differentcolors, including our top-selling GlasKap CRin cool roof white. History and Leadership – Johns Manville isthe pioneer of built-up roofing and, in fact,created the first BUR roof in America! Welater developed BURSI, originally knownas the Built-Up Roofing Systems Institute(now the Better Understanding of RoofingSystems Institute). More than 50,000graduates apply good roofing principlesin their organizations as a result of BURSItraining.Of course, various cements, coatings andsurfacings are available for a complete,single-source system. JM-approved asphaltis required for hot-applied BUR systems.Four-ply, gravel-surfaced, fiber glass built-uproof. For use over JM insulation, approved decksor other approved insulations, on inclinesup to 3 inches per foot (250 mm/m).JM BUR offers many advantages overcompetitive systems. Benefits include: Reliability – BUR is known to be one of themost reliable and longest lasting roofs onthe market. Guarantees are available for upto 30 years. Toughness – our gravel surfacing optionprovides one of the toughest roofsavailable, resistant to the many forms ofweather such as rain, snow, wind, hail andfire. Reflectivity for Cool Roofs – several capsheet and coating options have an SRI(Solar Reflective Index) that exceeds U.S.Ply FeltsGlasPly PremierGlasPly IVASTM StandardD 2178 Type VID 2178 Type IVBase SheetsGlasBase PlusPermaPly 28Ventsulation FeltD 4601 Type II Region 3 OnlyD 4601 Type IID 4897 Type IIFlashing and Cold Application SystemsGlasTite FlexibleCap SheetsGlasKap CRGlasKap GlasKap PlusD 3909D 3909D 3909 Region 3 OnlyRoofing CementsBestile Industrial Roof CementD 4586 Type IIRoof Coatings and SurfacingsTopGard Type ATopGard Type BTopGard 4000TopGard 5000Fibrated AluminumD 1227 Type IVD 6083D 6083D 2824 Type IIIPrimerConcrete PrimerD 417

Single Ply Systems from a CompanyYou Know and Trust.JM TPO and JM PVCSingle Ply Roofing Systems8JM TPO is the result of extensive researchand customer feedback. We evaluated andoptimized the formulation to deliver high-performing results – thickness over scrim, ozoneresistance, reflectivity, consistent thicknessacross the sheet and overall weather resistance. JM TPO clearly has the advantage overother products on the market, and now ourvalued customers are seeing the difference forthemselves. Most recently, in blind tests consisting of membranes from four leading TPOmanufacturers, contractors evaluated all of theproperties and performance characteristics thatmake a TPO membrane the best, such as weldwindow, ability to lay flat, workability andtexture. After more than 56 challenges acrossthe country, 90% of expert installers havechosen JM TPO as the best.Invinsa Roof Board,Mechanically AttachedJM TPO or JM PVC MechanicallyAttached MembraneJM-ApprovedFastenersENRGY 3PolyisocyanurateRoof InsulationJM-ApprovedFastenersDeckMechanically fastened, JM TPO or JM PVCsingle ply roofing system. For use overJM-approved decks or other approved insulation.JM PVC is a flexible, thermoplastic membranemanufactured using an ultraviolet-resistantpolyvinyl chloride and DuPont Elvaloy KEE(ketone ethylene ester) formulation.The formulation delivers: Twenty years of proven roofingperformance with nearly 600 millionsquare feet installed. One of the lowest life cycle costs of allinstalled roofing systems. High resistance to chemical exposure. High initial and three-year reflectivity forwhite JM PVC membrane at 86% and70%, respectively. Nonwicking polyester reinforcementhas a superior balance of physicalproperties for mechanically fastenedor fully adhered systems.JM PVC is available in 50-mil, 60-mil,60-mil MIN*, 72-mil MIN* and 80-mil thicknesses with 39 inch, 60 inch, 78 inch and120 inch widths. Stocked standard colors arewhite, grey and sandstone, with other colorsavailable upon request.* MIN is minimum thickness where no data points are lower thanthe listed thickness.

JM PVC Fleece Back membranes aremanufactured with a JM polyester fleeceembedded into the sheet during theextrusion process. As an integral componentto the membrane, the fleece provides: Protection of the back side of themembrane from exposed fasteners. Masking of surface imperfections inthe substrate. Additional reinforcement consisting ofdiscontinuous fibers to enhance physicalproperties. Ability to use as an asphalt-applied capsheet in some multi-ply systems.JM PVC Fleece Back is available in 50-mil,60-mil, 60-mil MIN*, 72-mil MIN* and80-mil thicknesses with 76 inch and 144inch width. White membrane is stockedas a standard and other colors are availableon request.JM PVC and PVC Fleece Back membranesare formulated to have long-term durability,and up to 25-year guarantees are available.A Smart Solution for theEnvironmentThe formulation of our white single plymembranes enables Johns Manville to be apartner in the U.S. Environmental ProtectionAgency’s Energy Star program. Thesehighly reflective surfaces help reduce electricity and natural gas consumption whenspecified with ENRGY 3 polyisocyanurateroofing insulation. The membranes can also* MIN is minimum thickness where no data points are lower thanthe listed thickness.help minimize the “heat island” effect in metropolitan areas. Testing on white membranesshowed initial reflectivity values that exceedEnergy Star’s guidelines.JM EPDM Single PlyRoofing SystemsThe JM thermoset single ply membrane iscalled JM EPDM (ethylene propylene dienemonomer). JM EPDM has superior weatherability through a wide range of temperaturesand conditions and it demonstrates superiorozone resistance.JM EPDM nonreinforced membranesare available in 45-mil, 60-mil and 90-milthicknesses. Membrane widths of up to 40feet (12.19 m) and lengths up to 100 feet(30.48 m) are available.With the appropriate JM single plysystem, you will be able to meet industryapprovals such as UL , FM Global andMiami-Dade County. Complete lines ofaccessory products are available, includingseam tapes, adhesives, caulk, terminationbars and flashings.9
