A flashing tape for window sills and custom shapes. DuPont™ FlexWrap™ is a moldable flashing tape made with Dupont™ Tyvek®, an elastic material, a polyolefin film, and a highly adhesive butyl sealant.

DuPont™ FlexWrap™ is uniquely engineered to address the issues of flashing the bottom corners at the window sill where damage is most likely to occur. DuPont™ FlexWrap™ is wrapped into the sill rough opening before the window is installed, making one step, seamless protection possible.

It also flashes round-top or custom shaped windows in one seamless step, to help create a complete building envelope seal. For more details, check the DuPont™ FlexWrap™  product specifications .
