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.
DuPont™ Flashing Tape is made from polypropylene film with a butyl rubber adhesive backing. In installed system water intrusion testing with no exterior cladding, it performed to ASTM E-331 standards, and shows no leakage at 300 Pa, even after thermal aging to 120 degrees F.
It is engineered to withstand the rigors of the job site, including UV exposure, for up to 120 days. In addition to bulk water holdout, DuPont™ Flashing Tape helps control air leakage, where windows and doors interface with sheathing or the weather barrier. As part of a complete building envelope system, this can help keep heated and cooled air in, and exterior air out, more effectively, for improved comfort and energy efficiency.
