VYCOR® represents the best solution for a house's longevity in the face of weather. As a fully-adhered weather barrier and flashing system, the products seal to the substrate, seal at overlaps, and seal around the fasteners that attach siding, trim, and decorative features. VYCOR® weather barriers and flashing deliver robust and worry free protection for the owner, and are easy for the contractor to install. VYCOR® weather barriers and flashing tapes are made in the USA by GCP Applied Technologies.

• 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.
• VYCOR® Plus high performance self-adhered flashing membrane provides premium protection against water and air infiltration in all critical non-roof detail areas.
• VYCOR® PRO flashing, with its unique film and non-asphaltic, butyl-modified adhesive technology, provides premium protection against water infiltration in all critical non-roof detail areas, that traditional building papers, felts, housewraps and other flashing products cannot match.
• VYCOR® Deck Protector self-adhered flashing membrane is formulated and tested to solve the problems of joist rot and deck corrosion.
