MFM Building Products, a manufacturer of a full envelope of waterproofing and weather barrier products for the building industry, announced that three of the company’s window flashing tapes now have ICC Approval, Evaluation Report ESR-2783. WindowWrap PSX-20, WindowWrap PowerBond and WindowWrap White meet the ICC-ES Acceptance Criteria for Flexible Flashing Materials (AC148), IBC and IRC 2015 standards. These flashing tapes also comply with AAMA 711, as a result of independent, third-party testing.

Each of the three WindowWrap products are 25 mils nominal thickness, self-adhering and self-sealing around fasteners to create a waterproof bond. These easy-to-use flashing tapes are compatible with most building and window materials, and prevent the infiltration of water, moisture, air and noise penetration into the building structure.

WindowWrap PSX-20 is a patented, aluminized multi-layer polymer film tape that has a UV exposure of 180 days. WindowWrap PowerBond has the same composition as WindowWrap PSX-20, but features a patented PowerBond adhesive system that aggressively adheres in temperatures as low as 25°F (-4°C), while remaining stable at elevated temperatures. WindowWrap White is a multi-purpose waterproofing tape composed of a white polymer facer.
