Carlisle Barritech VP: Air & Vapor Barrier 5 Gal

Carlisle Barritech VP: Vapor Barrier

Carlisle Barritech VP is a fluid-applied membrane made from inherently fireresistant materials. Carlisle Barritech VP is applied to exterior wall assemblies where it functions as an air barrier and a water-resistive barrier. Barritech VP may be installed down to 20°F. Barritech VP is vapor-permeable —moisture vapor can diffuse directly through the membrane. Barritech VP can be applied over concrete block, concrete, exterior gypsum sheathing, plywood, OSB and many other common building materials. The product is fully adhered to the substrate, flexible and rubber-like. Barritech VP is a singlecomponent, air-drying product applied by spray or roller at nominal 0.040″(40 mils) dry film thickness. The high film thickness and flexible, elastic properties enable Barritech VP to bridge cracks and seal around penetrations, which creates a truly continuous, monolithic air and water barrier.
