Products / GenFlex APP 180

GenFlex APP 180 is a granule-surfaced APP (atactic polypropylene) modified bitumen roofing membrane designed to be heat-welded, reinforced with a fiberglass-reinforced polyester non-woven mat made with 100% recycled PET fibers. It is used as a cap sheet or flashing sheet in single- or multi-ply APP applications for new construction and reroofing. The product data sheet (PDS 406) states it meets or exceeds ASTM D6222 Type I, Grade G, and lists an initial SRI of 33 for the standard white membrane.
