To best prevent costly water damage, consider the advantages of using DuPont™ FlexWrap™—a high performance, self-adhered flashing for window sills, doors and custom shapes on commercial buildings. This flashing efficiently conforms around custom shapes, bridging the interface between the rough opening and the building envelope. It’s especially great for protecting the vulnerable bottom corners of sills where water damage is most likely to occur. When used as part of the DuPont™ Weatherization Systems, DuPont™ FlexWrap™ also helps contribute toward U.S. Green Building Council LEED® points, helping you create more sustainable, durable commercial structures that continue to operate efficiently. And builders who use DuPont™ FlexWrap® can earn up to 6 points toward certification to the NAHB National Green Building Standard™.

How It Works:

DuPont™ FlexWrap™ is an extendable flashing material made with DuPont™ Tyvek® and a 100% butyl-based adhesive layer. DuPont™ FlexWrap™ is wrapped into the rough opening before the window is installed making one-step seamless protection possible. This flex wrap also flashes round-top or custom shaped windows in one seamless step.
