DuPont™ Flashing Tape is a self-adhered flashing that helps protect the heads and jambs of rectangular windows and doors from water intrusion providing a durable seal at the window-wall interface.

How It Works:

DuPont™ Flashing Tape is a self-adhered flashing that is designed to help protect the heads and jambs of windows. These areas can be subjected to wind-driven rain, which can find its way into a window and cause water damage.

DuPont qualifies its flashing products according to the AAMA 711-07 Voluntary Specification for Self Adhering Flashing Used for Installation of Exterior Wall Fenestration Products. DuPont™ Flashing Tape comes backed by a 10-year limited warranty from DuPont, a company dedicated to providing you with innovative and reliable products for over 200 years. Our DuPont Certified Installer Program also provides trained installation services, which is one more way to put the building science expertise of DuPont right at your fingertips.
