1 In Stock

DELTA®-TW FLASHING is a premium, durable, self-adhering flashing designed for through-wall applications. It adheres tenaciously to seal the interface between common building substrates, including lintels and brick ledges, and to all DELTA® air- and water-resistive barrier membranes.

This product is composed of a special polypropylene carrier film along with a pressure-sensitive butyl-base adhesive with an easily removed polyethylene (PE) release liner.

In addition, DELTA®-TW FLASHING is very puncture resistant with excellent self-sealing qualities that resist air and water ingress at vulnerable detail areas. It is non-bituminous, low odor, and suitable for LEED® rated projects by contributing to a more durable, sustainable, and energy-efficient structure.

It is fully compliant with AAMA 711-07 Voluntary Specification for Self-Adhering Flashing Used for Installation of Exterior Wall Fenestration Products.

DELTA®-TW FLASHING comes in 18” x 75’ (45.72 cm x 22.86 m) rolls. There are 4 rolls per box.
