DuPont™ Flashing Tape

Helps Seals Against Air and Water Intrusion Around Windows and Doors

<br><b>DuPont™ Flashing Tape</b> is a self-adhered flashing tape with improved workability made from polypropylene film with a butyl rubber adhesive backing. Engineered to withstand the rigors of the job site. <b>DuPont™ Flashing Tape</b> helps create a durable seal against water intrusion around heads and jambs of rectangular windows and doors. <br><br> In addition to bulk water holdout, <b>DuPont™ Flashing Tape</b> can help control air leakage. Where windows and doors interface with sheathing or the DuPont™ Tyvek® Water-Resistive Barrier (WRB), DuPont™ Flashing Tape can help keep heated and cooled air in and exterior air out more effectively. <br><br> As part of a complete building envelope system, <b>DuPont™ Flashing Tape</b> can help reduce the risk of water damage, increase building comfort, and improve energy efficiency.
