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.
