DuPont™ FlexWrap™
Extendable, Conformable, Self-Adhered Butyl Flashing for Windows, Doors, and Wall Penetrations
<br><b>DuPont™ FlexWrap™</b> is a premium extendable self-adhered flashing membrane specifically designed to provide seamless air and water barrier protection at window and door corners. Composition consists of a durable, micro creped DuPont™ Tyvek® top-sheet, a premium 100% butyl adhesive layer, and a specially designed split-release liner.
<br><br>
<b>FlexWrap™</b> offers a seamless application along window sill and arch-top head conditions. <b>FlexWrap™</b> conformability enables round-top or custom-shaped windows flashing in a seamless manner, eliminating the need to cut and place individual pieces of conventional flashing on an arched opening. Unlike some competitive flashing, FlexWrap™ does not require the use of mechanical fasteners in the flexed corner.
