State-of-the-art extrusion technology brings quality and consistency.
Johns Manville’s EPDM roofing materials are manufactured using advanced extrusion technology. The result is a membrane designed for superior weatherability through a wide range of temperatures and conditions. The Johns Manville EPDM difference is the level of precision quality control Johns Manville EPDM achieves during the manufacturing process.
The Johns Manville EPDM formulation has been developed to provide excellent ozone resistance and high tensile strength. Johns Manville EPDM membranes provide a quick, clean and cost-effective solution capable of being installed in a wide range of temperatures. Johns Manville EPDM membranes are available in several thicknesses, with or without polyester scrim reinforcement. Wider widths and fewer seams mean Johns Manville EPDM systems can help to improve efficiency during installation. And for your convenience, they can be installed fully adhered, mechanically fastened or ballasted. Johns Manville EPDM also offers a complete line of accessories, sealants and adhesives to help you get the job done right.

Tests indicate that competitors’ sheets are consistently at the lower end of the ASTM tolerance while JM sheets are much closer to a true 60 mil (ASTM allows +/- 10 percent variation in sheet thickness). Thicker sheets deliver a longer life cycle. We give you more roof for your money.
Cleaner sheets take less labor to prepare. A cleaner surface will allow the tape to stick better, which means a stronger seam and no contamination.
The smoother surfaces of these high-quality sheets come courtesy of using the most advanced extrusion technology available. Eliminating defects (pockmarks and air inclusions) with a consistent surface finish reduces the roofing membrane’s weak spots.
