DuPontTM 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.
Flashing is an essential part of construction and protection of your house. Its aggressive adhesive forms a permanent bond between the window flange and building substrate. It also self-seals around nails, screws and staples used to secure house wraps and felt paper.
