SubjectRainscreen walls
AbstractWIND-INDUCED PRESSURE difference is one of the forces that contributes to rain penetration of walls. It can be attenuated by using the pressure equalized rainscreen (PER) approach to wall design. In such a wallan air space that is located inside the exterior cladding is vented to the outside so that the pressure on the inside of the cladding equalizes to the pressure on the outside. As pressure equalization is the key element of the process, it is important that the system be fast enough to respond to most changes in exterior pressure. In 1963, Garden introduced the concept of the "open rainscreen" to building designers. The significance of this work lies in the formulation of basic design guidelines. These have subsequently been modified on several occasions in order to address the complicated nature of the interaction betweenwind-driven rain and wall systems. Killip and Cheetham (1984) reviewed the process of rain penetration through walls. They also performed simplified experiments to measure the pressure drop in the cavity for various venting and leakage conditions. Field measurements on PER walls were undertaken by researchers at the Institute for Research in Construction of the National Research Council of Canada (IRC/NRCC).
