WindowWrap® PSX-20 is a patented, self-adhering 25 mil waterproofing flashing tape constructed of a tough, aluminized, multi-layer polymer film. It is coated with a specially formulated rubberized asphalt to stand up to UV exposure.

WindowWrap® PSX-20 effectively stops water leaks around windows and doors while reducing outdoor noise and air infiltration.  The aggressive adhesive securely bonds the window flange to the exterior wall, and the rubberized asphalt self-seals around nails and staples.
