Permeable Air Barrier - Fluid Applied

Perm-A-Barrier VP 20
Perm-A-Barrier(r) VP 20 is a fire-resistive, one component, fluid-applied vapor permeable air barrier membrane that protects building envelope from air leakage and rain penetration, but allow the walls to 'breathe'. Perm-A-Barrier VP 20 has been evaluated to NFPA 285 within various wall assemblies with or without foam plastic insulation. Perm-A-Barrier VP 20 is plasticizer-free, phthalate-free and halogen-free, providing safe and environmentally friendly air barrier application.

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.
