CMHC: Research & Development Highlights

The use of brick veneer/steel stud (BV/SS) wall systems has preceded adequate formal scientific investigation into its long term serviceability and safety. Of particular interest to many parties is the performance of the walls under typical Canadian wmter conditions. This report outlines the findings of Part 3 of the laboratory testing program. The primary goal of the research was to investigate and document the potential for, and the amount and location of, moisture condensation problems in BV/SS type wall systems by subjecting sample wall systems to air pressure, vapour pressure and temperature differentials. A secondary goal was to determine thermal properties and air leakage characteristics as these are the main factors influencing condensation.
