PERM-A-BARRIER® VPL Low Temperature

About this product

PERM-A-BARRIER® VPL Low Temp (LT) is a two-component, fluid-applied, acrylic membrane that cures to form a resilient, monolithic, fully bonded elastomeric sheet when applied to construction surfaces at temperatures between 20 °F (-7°C) and rising to 60 °F (16°C). PERM-A-BARRIER® VPL LT 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 LT membrane is vapor permeable for wall assemblies requiring this "breathable" characteristic. As a vapor permeable membrane, this product 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 plane. Advantages Fire resistant - meets NFPA 285 as part of various wall assemblies with foam plastic insulation Plasticizer, Phthalate and Halogen-free - safe and environmentally-friendly Air tight - protects against air passage and associated energy losses. Meets new ASTM E2357 standard as required by IECC 2012 Vapor permeable - prevents moisture from being trapped in the wall cavity by allowing walls the ability to dry Low Temperature - can be applied at temperatures as low as 20°F (-7°C) Fully bonded - transmits wind loads directly to the substrate Seamless - continuous membrane integrity with no laps Damp surface tolerant - can be applied to damp-to-touch surfaces Strong adhesion to common construction substrates such as wood, block, concrete, OSB, gypsum sheathing and metal Compatible with PERM-A-BARRIER® Flashing Systems Applications Vapor permeable air barrier for new and remedial commercial and residential applications where application temperatures are between 20 °F (-7 °C) and 60 °F (16 °C) Concrete block walls with brick veneer or pre-formed cladding panels Steel or wood stud walls with exterior gypsum sheathing, brick veneer or pre-formed panels, plywood and OSB
