Description
Vycor
®
enV-S
™
sheet applied, vapor permeable weather resistive
barrier consists of a unique breathable carrier lm coated with
an adhesive that is specially designed to maintain vapor perme-
ability.
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.
Unlike conventional building wraps, installation of Vycor
®
enV-S
™
weather resistive barrier requires no mechanical fasten-
ing, and it seals around nails used to install siding and other wall
elements. This results in exceptionally low levels of air leakage,
and improved energy efciency of the building.
Advantages
• Fully-adhered—installation requires no mechanical fasteners
or taping of seams
• Water resistive—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 efciency
