How it Works:
FlexWrap integrates easily with all DuPont air and water barriers, to help seal the building envelope for improved durability and energy efficiency. Correctly installed, Flex Wrap NF can help stop water from getting at the corners of windows and doors. In turn, that can help prevent water damage, such as wood rot and corrosion, as well as mold. Keeping air and water out can also help maintain insulation R-value, for improved energy efficiency.
