Description

A premium performance, extendable 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. FlexWrap also flashes round-top or custom-shaped windows in a seamless manner, eliminating the need to cut and place individual pieces of conventional flashing on an arched opening. FlexWrap can be installed at external temperatures as low as -4°C (25°F) as long as the surface is clean and free from frost and ice.
