Air-Shield Aluminum Flashing is a new, self-adhering, roll-type flexible membrane flashing with an aluminum facer. This nominally 40-mil thick product is reportedly an air, vapor, and liquid moisture barrier. When properly applied, it can reduce the risk of rot and mold development.

The flashing reportedly provides protection against water infiltration in critical detail areas, such as window and door openings, deck-to-wall intersections, corner boards, wall-to-wall tie-inns, and many other non-roof detail areas. The aluminum-faced film provides improved sealant adhesion and extended UV exposure for up to one year.
