Butyl Flashing Tape

Material: White conformable polyethylene film with a thick non-asphaltic butyl adhesive and brown kraft release liner.
Description: Our Butyl Flashing Tape system utilizes a non-asphaltic butyl mastic adhesive to provide long-term waterproof sealing around window and door installations. It has a white, conformable polyethylene film to allow complete puncture sealing so water won't get in around nail and screw holes. This film also allows the product to be shaped around half-round and circular windows.
