This 2 -roll foam window sealing kit provides a total of 13 in. of high-quality foam strip, with each individual roll measuring 2 in. W x 1 in. T x 6.5 ft. L. Crafted from non-toxic, harmless materials, the foam tape boasts strong, long-lasting adhesion, along with excellent flame retardancy, heat insulation, and oil resistance properties. It will not peel or degum over extended use, and can perform consistently across a wide temperature range from -40°C to 96°C. Designed to fit and seal uneven gaps, irregular surfaces, and narrow openings, this weatherstrip effectively blocks cold and hot drafts while reducing unwanted ambient noise. It is suitable for use on windows, doors, AC units, HVAC systems, refrigerators, automobiles, RVs, and marine vessels. Installation is straightforward and requires no specialized tools: first measure the gap to cut the appropriate length of tape, clean the target surface thoroughly to remove dirt and debris, peel off the protective backing paper, then press the foam strip firmly to expel trapped air and ensure a secure, tight bond.
