Tyvek Flex Wrap NF by Dupont
(NF: no fasteners needed)
Self-Adhered Flashing Helps Seal the Building Envelope - Made for window sills, doors, and custom shapes and openings. Self-adhered butyl flashing helps prevent water intrusion at window and door sills without mechanical fasteners.
DuPont FlexWrap NF self-adhered flashing does not require mechanical fasteners, even in flexed corner areas around building openings. This allows it to provide easy, one-step insulation for hard-to-seal corners around windows and doors. FlexWrap NF is designed to help protect vulnerable corners against air and water intrusion, as part of a complete DuPont Building Envelope Solution. It’s effective across a range of window and door designs and a wide range of typical wall substrates, including OSB, plywood, gypsum, concrete masonry unit (CMU) and other non-nailable sheathing materials.
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.
