Application of the Rain Screen Concept to Wood-Frame Walls

Abstract

The walls were subjected to simulated wind-driven rain. In addition, the test walls were subjected to both steady and gusty winds. In the latter tests, the air pressure loads on the cladding elements and other components within the walls were recorded and analyzed. The study also examined the pressure equalization performance of one of the cladding systems on a construction model. A fully compartmentalized cavity (one that is separated into small areas to maintain an air pressure equal to the exterior air pressure), a continuous cavity and other types of compartmentalizations were examined. This allowed for a detailed Examination ofthe pressure equalization performance of the cladding system under real wind conditions, and the compartmentalization requirements of the cavity behind the cladding system.
