MFM Window Wrap Flashing Tape

MFM Window Wrap White is a 25-mil self-adhering waterproofing membrane tape designed to create an airtight, watertight, sound-reducing, and bug-proof seal around windows and doors. Composed of a white polymer film bonded to a rubberized asphalt adhesive, this window wrap adheres securely to clean, dry surfaces, including wood, vinyl, metal, masonry, sheathing, and house wrap. Ideal for preventing moisture intrusion and mold growth, this window flashing tape is safe for direct application over sheathing or under siding but should not be applied over flexible vinyl gaskets. It must be installed in dry conditions above 35 degrees Fahrenheit and covered within 30 days of application. With easy peel-and-stick installation, this window tape ensures long-lasting protection against air and water infiltration. MFM backs WindowWrap with a 10-year limited warranty, making it a reliable solution for both residential and commercial construction projects.
