What is Insultex House Wrap®? It is a multi-ply weatherization membrane that provides a protective layer under a building’s outer covering that resists water and air infiltration, preventing mold and mildew buildup that could cause structural rotting. What differentiates Insultex™ from its competition is the fact that it offers an R-Value, the term used to measure thermal resistance, and is most commonly used when referring to the insulating qualities of a building structure, thus increasing energy efficiency.
Insultex™ is a revolutionary structured cellular fabric that incorporates countless evacuated closed micro-cells that significantly reduce heat transfer through the fabric. Insultex™ is the newest thermal insulation on the market promising to revolutionize insulation as we know it from outerwear, tents, boots, sleeping bags, coolers and now house wrap, just to name a few.
