R-Guard - VB (Vapor Barrier)

VB (Vapor Barrier)

Fluid-applied air & water-resistive barrier and water vapor barrier PROSOCO R-GUARD VB is part of the family of R-GUARD products developed to maximize wall R-values by preventing the unwanted movement of water and air through building envelopes. Utilize R-GUARD VB as the primary air barrier/water-resistive barrier over properly prepared above grade structural walls prepared with R-GUARD joint and seam treatments and liquid flashing membranes.

PROSOCO R-GUARD VB is a fluid-applied air and water-resistive barrier that stops air and water leakage in cavity wall, masonry veneer construction, as well as in stucco, EIFS and most other building wall assemblies. Once on the substrate, the easily applied liquid quickly dries into a rubberized, highly-durable, water-resistant membrane. R-GUARD VB performs the function of both a vapor barrier and an air and water resistive barrier. Spray-grade R-GUARD VB is ideal for special construct types that require protection from the passage of air, liquid water and water vapor.

R-GUARD VB reduces heating and cooling costs and lowers the risk of mold and mildew. Compared to self-adhered or mechanically fastened sheet wraps, easy-to-use R-GUARD VB provides superior protection against penetration of liquid water and water vapor.

Use R-GUARD VB as a high-performing water resistive barrier, vapor barrier, or as part of a continuous building-wide air barrier system. The durable membrane conforms and adheres to common building surfaces and is compatible with most paints, sealants and self-adhered waterproofing or air barrier components. Appropriate for vertical, above-grade applications to structural sheathing, CMU, cast concrete and most other common building materials.
