High performance self-adhered flashing with non-asphaltic butyl-modified adhesive
The primary purpose of a flashing tape is to prevent the migration of water and air through window and door openings. Product performance depends on the adhesive bond between the flashing and the substrate. This is especially true for irregularly surfaced materials such as OSB. The better the adhesive seals itself into the peaks and valleys of the substrate, the better the barrier against water and air migration.
