| Abstract: |
| This project involves both laboratory development and field testing of new rainscreen testing procedure termed the Cavity Excitation Method (CEM). The laboratory work was undertaken in the construction laboratory of the Engineering Department of Queens University. The field work involved a building in Montreal, Quebec, 'Le Clos St-Andr¨¦'. The test objectives included determination of the overall air leakage areas from the venting, the compartment seals and the air barrier leaks. It also included a performance signature of the wall's rainscreen dynamic response. The results of the laboratory exploration and development were used to formulate a test method that related the predicted pressure equalisation performance of a rainscreen design with on-site compliance test results.
"This project was commissioned by CMHC and Public Works Government Services Canada (PWGSC) to further advance the application of the rainscreen principle to exterior wall design and construction of both residential and commercial buildings."--Executive Summary. |
