POWERply® Endure® 300 FR

Fire Rated, Granule Surfaced, High Tensile, Bilaminate Reinforced SBS Modified Bitumen Membrane

POWERply® Endure® 300 FR is designed for roof membrane and flashing applications in hot-applied asphalt adhesives over multi-ply systems where a high strength, fiberglass reinforced, granule surfaced membrane is desired.  It features GranuLock™, a unique surface treatment that reduces granule loss to practically zero; anti-wick fabric; and a RooF-ID™ chip embedded in each roll enabling the membrane to be identified after installation, if necessary. POWERply Endure 300 FR is also suitable for application in a cold process modified bitumen system.


POWERply Endure 300 FR is an asbestos free, granule surfaced, modified bitumen membrane with fire resistant characteristics.  It consists of specially selected bitumens, modified with SBS rubber along with RET and urethane high performance elastomers and reinforced with a combination polyester and fiberglass mat with a scrim core.  POWERply Endure 300 FR is furnished with a factory applied white granule surfacing.  This product exceeds the requirements of ASTM D 6162, Type III, Grade G.  POWERply Endure 300 FR roof systems are fire rated by Underwriters Laboratories for an exterior fire hazard.
