Flexo-Flash is a 40-mil self-adhering through-wall flashing manufactured with a rugged white cross-woven polyethylene facer and a proprietary clear pressure-sensitive adhesive.

The non-asphaltic adhesive will not drool like rubberized-asphalt flashing when exposed to heat and does not require primer. Flexo-Flash provides puncture, tear, and slicing resistance while bonding to a variety of common construction substrates.
