Permeable Air Barrier Systems

Perm-A-Barrier® VP
Perm-A-Barrier® VP is vapor permeable for wall assemblies requiring this ?breathable? characteristic. As a vapor permeable membrane, Perm-A-Barrier VP permits the transfusion of water vapor that may otherwise condense in the wall structure; but is impermeable to liquid water, which allows the material to act as a water drainage plain.

Perm-A-Barrier® VP Low Temp (LT)
Perm-A-Barrier® VP LT is a two component, fluid-applied vapor permeable air barrier membrane for low temperature application. As a vapor permeable membrane, Perm-A-Barrier VP LT permits the transfusion of water vapor that may otherwise condense in the wall structure; but is impermeable to liquid water, which allows the material to act as a water drainage plain.

Perm-A-Barrier® VPO
Perm-A-Barrier® VPO is a one component, fluid-applied vapor permeable air barrier membrane that provides continuous air tightness and water protection throughout the wall assembly. Perm-A-Barrier® VPO is blackish green and designed for exposure to indirect and intermittent sunlight, such as behind open joint rain screen systems.

Perm-A-Barrier® VPS
Perm-A-Barrier® VPS (Vapor Permeable Sheet) is a self-adhering vapor permeable air barrier membrane consisting of a breathable carrier film with a specially designed adhesive. Perm-A-Barrier VPS provides superior protection against the damaging effects of air and water ingress on building structures.
Perm-A-Barrier VPS is vapor permeable for wall assemblies requiring this breathable characteristic. As a vapor permeable membrane, Perm-A-Barrier VPS permits the diffusion of water vapor that may otherwise condense in the wall structure; but is impermeable to liquid water, which allows the material to act as a water drainage plain.
