AbstractControlling rain penetration in the building envelope is a continuing task for building engineers and architects. In 1963, Garden introduced the "Open Rainscreen" principle, in which external wind pressure, one of the forces that contributes to rain penetration, is controlled by equalizing it with internal cavity pressure through venting. As pressure equalization is the key element of the process, these walls are known as Pressure Equalized Rainscreen Walls (PER). Application of this wall multiplied rapidly and it is considered the most reliable tool to control rain penetration. Yet few designers seem to have a clear knowledge or rules of designing such walls; thus the problem of rain penetration is not prevented totally.
