DescriptionWind-driven rain provides the primary external moisture load for exterior walls.Water absorption by the cladding, runoff, and penetration through the cladding or at details determine how a wall system performs. In this paper we describe a new laboratory facility that can create controlled outdoor and indoor conditions and use it to investigate the water management performance of a typical exterior wall assembly. Specifically we have quantified how much water gets past the cladding and hits the water-resistive barrier under particular conditions for a common lap siding.
