    Product Description

    Don't Just Wrap it... Seal ist with Vycor® enV-S™

    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 beneits 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 eiciency 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.

    Features and Benefits:

    • Fully adhered - installation requires no mechanical fasteners or taping of seams
    • Water resistant  - forms a fully adhered barrier against wind driven rain
    • Vapor permeable - “breathable” membrane prevents moisture from becoming trapped in the wall cavity and provides walls the ability to dry
    • Air resistive - greatly reduces air leakage and helps improve building energy eiciency
    • Strong adhesion - to unprimed plywood and oriented strandboard (OSB).
    • Controlled thickness - factory made sheet ensures consistent, non-variable site application
    • Lightweight - allows for easy handling and installation
    • Installation lexibility - may be exposed up to 90 days
    • System solution - when used in combination with Vycor® Flashings

    Vycor® enV-S™  vs. Traditional House Wrap

    Unlike traditional house wrap, Vycor® enV-S™ looks sealed and attractive during construction.

    Improved Energy Efficiency

    • The Oak Ridge National Laboratory recently tested Vycor® enV-S™ weather resistive barrier compared to a leading house wrap brand.
    • Test results showed that Vycor® enV-S™ has a 7 times lower air leakage rate compared to the leading house wrap
    • A homewoner can expect to sabe up to 56% ($669 per year) in annual energy savings.

    *Data is based on the Oak Ridge National Laboratory (ORNL) evaluation of the annual energy savings potential a homeowner can achieve, when using Vycor® enV-S™ weather resistive barrier compared to a leading housewrap brand.
