DuPont FlexWrap

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

DuPont™ FlexWrap™ 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. DuPont™ FlexWrap™ 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.
