A fastener-free way to prevent water intrusion
A self-adhering butyl flashing that integrates with DuPont air and water barriers, FlexWrap™ NF is a one-step solution for keeping water from seeping through window and door sills.
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.
