DuPont™ StraightFlash™ is an innovative, single-sided, self-adhered flashing solution that bridges the gap between the rough opening and building envelope to protect against water intrusion around heads and jambs of rectangular doors, windows and other gaps. By sealing vulnerable areas around openings, DuPont™ StraightFlash™ can help improve the durability and energy efficiency of both homes and commercial structures.

DuPont™ StraightFlash™ flashing combines a DuPont™ Tyvek® topsheet with a 100% butyl-based adhesive layer, merging the strength, durability and water resistance of Tyvek® material with the convenience and flexibility of a self-adhered flashing. The result: premium door and window flashing protection that helps keeps rain out and integrates seamlessly with other DuPont™ air and water barriers in a complete building envelope system.
