Polyguard UV2-40 is a 40-mil rubberized asphalt waterproofing sheet membrane, laminated to two layers of high strength polyethylene film, with a top protective layer of aluminum. The coating is supplied in rolls, with an easy to remove film release sheet, for ease of application. Polyguard UV2-40 can be used in higher exposure houses that require a more robust waterproofing strategy. The protective layer of aluminum provides a UV resistance exposure time, of up to two years, before needing to be covered. Not intended to be used as a roofing material.
