WSM2: Liquid Applied Vapor Air Barrier - Uv stable, green, and bonding weatherskin waterproof membranes

The construction industry has historically relied on home and building wrap (paper & tar paper) as a solution for vapor air barrier (rain screen). The production of these home wrap materials relies heavily on textile mills, and harmful oil and gas biproduct like tar to create the final product. The application of the product is cumbersome and historically unreliable. You create penetration points every time you put a staple through the paper. Wind blows the paper off. It tears and folds during construction, and ultimately requires re-work. These products provide very little in terms of the buildings energy conservation as well. The Solution, seamless, water based product has none of the waste, none of the failing points, none of the chemicals, and none of the installation challenges that the home wrap has. The energy and cost savings both in production and during the solutions lifespan are more than tangible. You spray it on. Your building uses less energy. You now have a solution that lasts.
