SOPREMA, Inc. is a world-wide leading manufacturer in the commercial roofing and waterproofing industry. Founded in 1908, SOPREMA has specialized in the development and production of SBS (styrene butadiene styrene) engineered asphaltic membrane.
View Corporate OverviewSOPREMA’s unique qualifications in SBS technology are built upon an extraordinary track record of innovation and technical expertise. Through our extensive knowledge of chemical engineering, manufacturing, system design and installation, SOPREMA has continued to be an industry leading
force in SBS.
In the United States, SOPREMA has evolved into a true “building envelope” company featuring products such as below-grade waterproofing solutions, liquid applied waterproofing systems, self adhered underlayments, air barrier, vapor barrier and garden roofs.
Today’s commercial roofing offers extraordinary opportunities to be on the forefront of tomorrow’s building initiatives. This is a position quite familiar to Johns Manville. Now, as owners and specifiers demand not only top-quality installation and performance, but increasingly are looking for new, cost-effective alternatives and environmentally smart solutions, they continue to look to JM.

When you specify a commercial roof from JM, you get far more than just superior systems and products. We complement the roofing investment with a variety of unique programs that bring added value to product information, installation and long-term performance of your roof.
Johns Manville Modified Bitumens:
Johns Manville has been producing quality SBS (Styrene-Butadiene-Styrene) products since 1986. SBS products are comprised of a reinforcement of either fiber glass, polyester or a combination of both. SBS is a rubberized modifier that increases the overall performance of the sheet by providing superior elongation and recovery characteristics. SBS modifiers extend the service range of the product so it can be handled in cooler temperatures without cracking or shattering, or in warmer temperatures without softening to the point where it begins to flow. In all instances, high performance prevails. SBS Products Reinforcements play a key role in performance. Since the inception of modified bitumen products, several reinforcements have entered into the JM SBS line, each targeting specific performance needs. Fiber glass reinforcements offer tensile strength and dimensional stability required for rooftops with heavy traffic areas.
Like our SBS products, our APP modified bitumen products provide high-tensile strength while maintaining critical flexibility. However, through the scientifically advanced formulation, our APP membranes (coated with a proprietary blend of asphalt and atactic polypropylene) are more compatible with heat-welding application methods. With APP, hot mopping is no longer necessary because the bottom coating may be heated to a point where it acts as its own adhesive, bonding the sheet to a substrate and bonding the overlapping edges. While all our APP membranes are designed to be heat welded, some may also be applied in cold adhesive. These products have a sand backing in lieu of the burn-off film often found on the heat-welded products.

Johns Manville EPDM Roof Systems:
The JM thermoset single ply membrane is called JM EPDM (ethylene propylene diene monomer). JM EPDM has superior weatherability through a wide range of temperatures and conditions and it demonstrates superior ozone resistance.
JM EPDM nonreinforced membranes are available in 45-mil, 60-mil and 90-mil thicknesses. Membrane widths of up to 40 feet (12.19 m) and lengths up to 100 feet (30.48 m) are available. With the appropriate JM single ply system, you will be able to meet industry approvals such as UL®, FM Global® and Miami-Dade County. Complete lines of accessory products are available, including seam tapes, adhesives, caulk, termination bars and flashings.

Johns Manville PVC Roof System:
JM PVC is a flexible, thermoplastic membrane manufactured using an ultraviolet-resistant polyvinyl chloride and DuPont™ Elvaloy® KEE
(ketone ethylene ester) formulation.
The formulation delivers:
• Twenty years of proven roofing performance with nearly 600 million square feet installed.
• One of the lowest life cycle costs of all installed roofing systems.
• High resistance to chemical exposure.
• High initial and three-year reflectivity for white JM PVC membrane at 86% and 70%, respectively.
• Nonwicking polyester reinforcement has a superior balance of physical properties for mechanically fastened or 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 and 120 inch widths. Stocked standard colors are white, grey and sandstone,

JM TPO is the result of extensive research and customer feedback. We evaluated and optimized the formulation to deliver high-performing results – thickness over scrim, ozone resistance, reflectivity, consistent thickness across the sheet and overall weather resistance. JM TPO clearly has the advantage over other products on the market, and now our valued customers are seeing the difference for themselves. Most recently, in blind tests consisting of membranes from four leading TPO manufacturers, contractors evaluated all of the properties and performance characteristics that make a TPO membrane the best, such as weld window, ability to lay flat, workability and texture. After more than 56 challenges across the country, 90% of expert installers have chosen JM TPO as the best.
