Vycor® enV-S™ sheet-applied, self-adhered weather resistive barrier provides exceptional protection against water damage and air infiltration. It helps preserve the home's structural integrity and contributes to improved energy efficiency.

Vycor® enV-S™ represents the next generation of weather resistive barriers and is designed to provide superior weather protection, and improved energy performance. The membrane brings together the weather protection benefits of a self-adhered membrane, with the breathability of traditional housewraps. The unique adhesive coating bonds strongly to the sheathing, but remains vapor permeable. Vycor® enV-S™ resists damage in windy conditions, leading to less rework and a high quality appearance. Unlike conventional building wraps, installation of Vycor® enV-S™ weather resistive barrier requires no mechanical fastening or taping of seams. The membrane bonds to the sheathing, self seals at overlaps, and seals around fasteners used to install siding and other wall elements. This results in exceptionally low levels of air leakage, and improved energy efficiency of the building. Keeping walls dry is the key to preventing rot of structural elements and mold growth. Vycor® enV-S™ fully-adhered barrier protects against wind driven rain. Vycor® enV-S™ vapor permeable membrane allows the wall system to "breathe", and water vapor to escape.
