Building science for the building process
Rooted in years of building envelope expertise, DuPont™ Flashing Tape is a proven weapon against the elements during construction. This self-adhesive tape protects the heads and jams of rectangular windows and door, with bulk water holdout, air leakage control, and more.
Help protect heads and jambs of rectangular windows and doors from air and water intrusion with DuPont™ Flashing Tape. DuPont™ Flashing Tape helps protect the heads and jambs of rectangular doors and windows from air and water intrusion. Wind-driven rain and outdoor air can find their way into walls around windows and doors. By helping to seal the building envelope, self-adhered DuPont™ Flashing Tape can help reduce the risk of water damage, increase building comfort, and improve energy efficiency.
