Description

air and water-resistive barrier for rain screen construction

Cat 5 Rain Screen is a roller-applied air and waterproof barrier that produces 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) is specially formulated to meet the unique requirements of pressure-equalized rain screen construction. The roller-applied 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.
