Permeable Air Barrier - Fluid Applied
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 is a two component, fluid-applied vapor permeable air barrier membrane for low temperature application. 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.
