Assures a watertight roof that is easy to maintain and saves energy through its heat reflecting characteristics. It is highly puncture resistant, has superior tensile strength and tear resistance, and is both reflective and refractive to UV rays. The Brite-Ply Membrane resists uneven weathering, fading or chalkiness of the installed roof system. It passes the ASTM 20 year accelerated aging test with no discoloration. Must order installation component kit (#2004011) for complete kit.
