Polyguard UV40 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 UV40 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.
