Barritech NP-LT is of 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 many other common building material, The product is fully adhered to the substrate, flexible and rubber-like. Barritech NP-LT is a single-component, air-drying product applied by spray or roller at nominal 0.04" (40 mils) dry film thickness. The high film thickness and flexible, elastic properties enable Barritech NP-LT to bridge cracks and seal around penetrations, which creates a truly continuous, monolithic air, vapor and water barrier.
