GCP Perm-A-Barrier Vpl 52 Gal Drum

52 Gallon Drum, 1-Component, Acrylic, Fluid Applied, Vapor Permeable, Green PERM-A-BARRIER® VPL Air Barrier Membrane

PERM-A-BARRIER® VPL is a fluid applied, one component, acrylic membrane that cures to form a resilient, monolithic, fully bonded elastomeric sheet when applied to construction surfaces. For application at temperatures between 20 Deg F (-7 Deg C) and rising to 60 Deg F (16 Deg C). Please use PERM-A-BARRIER® VPL LT. (Please a different datasheet) PERM-A-BARRIER® VPL membrane provides superior protection against the damaging effects of air and liquid water ingress on building structures. The product creates a solid barrier against air infiltration and exfiltration, which minimizes associated energy loss and condensation problems. PERM-A-BARRIER® VPL membrane is vapor permeable for wall assemblies requiring this "breathable" characteristic. As a vapor permeable membrane, it 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.
