MFM Building Products, a manufacturer of a full envelope of waterproofing and weather barrier products for the building industry, is proud to announce that three of the company’s window flashing tapes comply with AAMA 711-07 as specified in ICC-ES AC38 (02-11) as the result of independent, third-party testing. The products include: WindowWrap PSX-20, WindowWrap PowerBond, and WindowWrap White.

AAMA 711 is a voluntary specification outlined by the American Architectural Manufacturers Association to establish the test methods and minimum performance requirements for self-adhering flashing products used for the installation of exterior wall fenestration products.

Each of the three 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 adhesive system that aggressively adheres in temperatures as low as 25 degrees Fahrenheit (-4 degrees Celsius), while remaining stable at elevated temperatures. The white product is a multi-purpose waterproofing tape composed of a white polymer facer.
