Fluid-Applied, Acrylic Air Barrier Membrane
From Grace Construction Products
Grace Construction Products introduces the newest member of its Perm-A-Barrier® family of air and vapor barrier products, Perm-A-Barrier® VP.
Perm-A-Barrier® VP is a fluid-applied, acrylic air barrier membrane that provides continuous air tightness and water protection throughout the wall assembly, while allowing condensation-causing water vapor to escape.
It is designed for use in above-grade wall assemblies and is suitable for new and remedial commercial and residential construction. By spraying it directly onto substrates, including damp-to-touch concrete and masonry surfaces, Perm-A-Barrier VP becomes part of the structural wall system. This simple application method requires minimal surface preparation and eliminates the need for fastener holes that can promote air and water penetration and increase the likelihood of mis-lapping or tearing.
