Product Details
Barritech NP-LT has a similar composition to Barritech NP, except the former is adapted to allow installation below freezing. Barritech NP-LT enables work to continue during winter. Barritech NP-LT is a fluid-applied membrane of fire-retardant synthetic polymer composition. Barritech NP-LT is applied to exterior wall assemblies where it functions as an air barrier, vapor barrier, and a water-resistive barrier. Barritech NP-LT can be applied over concrete block, concrete, exterior gypsum sheathing, plywood, OSB, and other common building materials. The product fully adheres to the substrate, is flexible, and is rubber-like. Barritech NP-LT 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-LT 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). Monolithic coverage and self-sealing properties around fasteners enable an air and watertight installation. 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.
Can be installed in sub-freezing conditions - allows work to continue in winter. Can also be installed in warm weather - no need to discard leftover winter inventory
Fire-resistant 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
VOC compliant, low-odor composition contributes to comfort and safety during installation
