Product Details

Barritech NP is a fluid-applied membrane made of a fire-retardant, synthetic polymer composition. Barritech NP is applied to exterior wall assemblies, which function as an air barrier, vapor barrier, and water-resistive barrier. Barritech NP can be applied over concrete block, concrete, exterior gypsum sheathing, plywood, OSB, and other common building materials. The product is fully adhered to the substrate, flexible, and rubber-like. Barritech NP is a single-component, air-drying product applied by spray or roller at a nominal 0.040" (40 mils) dry film thickness. The high film thickness and flexible, elastic properties enable Barritech NP to bridge cracks and seal around penetrations, creating a continuous, monolithic air, vapor and water barrier.

Dries to a distinctive dark blue color for easy identification (light blue color when wet). Non-asphalt composition permits contact with many window and joint sealants. Spray-through standard, one-part equipment provides a simple and quick installation. Easy, water clean-up of tools & equipment reduces harmful chemicals on the jobsite

  • Fire-retardant composition permits use in many wall assemblies requiring NFPA 285

  • Tough construction and 180-day UV resistance allows flexibility in schedule

  • High water resistance of cured membrane permits use in high moisture exposure areas

  • Non-flammable & fume-free composition contributes to safety during installation

  • Monolithic coverage and self-sealing properties around fasteners enable an air and watertight installation
