VB (Vapor Barrier)

Fluid-applied air & water-resistive barrier and water vapor barrier

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.

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.

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.
