Poly Wall WindowSeal Window Flashing Tape is a self-adhering, self-sealing, waterproof rubberized asphalt tape, laminated to polyethylene film. The finished product is supplied in rolls, with an easy to remove film release liner. WindowSeal is available in 20 mil thickness and a variety of roll sizes. WindowSeal Flashing Tape is used to strip in or flash straight window frames, door frames, and other construction seams. If material is to be applied to round-top or custom shaped areas, ArcFlash should be used. WindowSeal is designed to be used in ambient temperatures and surface temperatures between 40° F (5° C) and 120° F (49° C). Using Poly Wall’s Polybond Liquid Adhesive can lower the WindowSeal application temperature to 25° F (-4° C). When installing in cold weather, store inside at room temperature for 24 hours prior to installation.
