This is how the team that built the R.W. Kern Center chose R-Guard as the air & water barrier for its Living Building Challenge project.
Cat 5 Rain Screen
air and water-resistive barrier for rain screen construction
Cat 5 Rain Screen
air and water-resistive barrier for rain screen construction
Description
Cat 5 Rain Screen is an air and waterproof barrier that goes on the wall with a sprayer or roller to produce a highly durable, seamless, elastomeric weatherproof membrane on exterior sheathing behind open-jointed or vented rainscreen cladding. Use Cat 5 Rain Screen as the primary air and water barrier over above-grade wall assemblies.

OVERVIEW
R-Guard Cat 5 Rain Screen is a fluid-applied, waterproofing, and air and water barrier membrane that combines the best of silicone and polyurethane properties. This single-component, silyl-terminated polymer (STP) can be applied with a sprayer or roller and is specially formulated to meet the unique requirements of pressure-equalized rain screen construction. The air and waterproof barrier produces a highly durable, seamless, elastomeric weatherproof membrane on exterior sheathing behind open-jointed or vented rain screen cladding. Cat 5 Rain Screen is proven to prevent water and air penetration of the building envelope in conditions ranging from everyday weather to the drenching rains and 155-mph winds of a Category 5 hurricane. Cat 5 Rain Screen can be applied in unfavorable weather conditions to dry or damp substrates. This feature eliminates many weather-related construction delays and accelerates the “drying in” of new buildings. The durable, elastomeric membrane adheres to most surfaces, is immediately waterproof and is compatible with most sealants and waterproofing or air barrier components.
