Roofing Membranes

U.S. Ply has engineered and developed DuraWeld™ APP (Atactic Polypropylene), torch applied only, SafeWeld™ APP (Atactic Polypropylene), cold adhesive applied with heat welded laps, DuraFlex™ SBS (Styrene-Butadiene-Styrene), hot asphalt or cold adhesive applied and DuraFlex™ TG SBS (Styrene-Butadiene-Styrene), torch grade modified bitumen membrane to meet or exceed the industry standards for high performance membranes.

U.S. Ply uses only raw materials, for our premium products, which are made or originate in the USA. We begin with prime grades of asphalts which are then modified with either thermoplastic (APP) or elastomeric (SBS) polymers. The result is a modified bitumen compound that demonstrates revolutionary waterproofing characteristics, extreme heat resistance, low temperature flexibility and elongation properties. U.S. Ply then strategically adds reinforcements of fiberglass, polyester or composite fibers in the modified bitumen compound to incorporate additional performance characteristics into the membrane.

To complement the modified bitumen membranes, U.S. Ply offers an extensive line of insulations, fiberglass base sheets, interply felts, and cap sheets, under the USP™ label for Built-up roofing applications and/or hybrid BUR/modified roofing systems.  U.S. Ply produces its membranes with granule surfacing for added UV protection and a mineral-textured look, or unsurfaced, ready for application of a wide range of different surfacing materials.
