Fire Resist Barritech NP is a fluid-applied membrane made from inherently fire-resistant materials. Fire Resist Barritech NP is applied to exterior wall assemblies where it functions as an air barrier, vapor barrier and a water-resistive barrier. Fire Resist Barritech NP 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. Fire Resist Barritech NP is a single-component, 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 Fire Resist Barritech NP to bridge cracks and seal around penetrations, which creates a truly continuous, monolithic air, vapor and water barrier.
