Fully-adhered weather resistive barrier sheet

PRODUCT DATA SHEET

Product Advantages

• Water resistive

• Seals around nails

• Vapor permeable

• Air resistive

• Easy to install

• Improves energy eciency

Description

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 eciency 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.

Advantages

• 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 eciency

• 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 ﬂexibility—may be exposed up to 90 days

• System solution—when used in combination with

Principle Application Vycor® enV-S™ water and air resistive barrier can be used for new and remedial residential construction applications. It is installed onto exterior wall substrates and behind the exterior siding or cladding.
PAGE 3
If a separation sheet is used, it must be permeable to allow the wall system to breath. Any separation sheet recommended by stucco manufacturers is acceptable. Membrane Repairs Repairs must be made using Vycor® enV-S™ barrier sized to extend 6 in. (150 mm) in all directions from the perimeter of the affected area. If repairs are required, carefully cut out affected areas and replace in similar procedure as outlined in the text above.
