A rainscreen is the exterior weather-facing surface of an exterior wall detail that stands off from the moisture-resistant surface of the structural backup wall. The rainscreen is the first interruption between conditions that exist on the outside of a walled building and conditions that are required on the inside of a walled building. A veneer that does not stand off from the moisture-resistant surface of the structural backup wall to create a cavity is not a true rainscreen. However, a masonry veneer can be a rainscreen. In a rainscreen the air gap allows the circulation of air across the air vapor barrier. This helps remove condensation and helps direct water away from the dry insulation where it otherwise might cause problems such as mould formation and water leakage. The Air Vapor barrier prevents water molecules from entering the insulated cavity but allows the passage of air.
