Vancouver Test Hut Phase IV Wall Assemblies
The Vancouver Test Hut is a 900 square foot field testing facility located in Coquitlam, BC, on the rooftop of the two story commercial office building occupied by team member and builder, Gauvin 2000 Construction Ltd. The test facility can accommodate up to seven wall test panels on each cardinal direction (a total of 28 wall test panels).
The Vancouver Test Hut Project is a multi-year study led by Building Science Corporation and Gauvin 2000 Construction Ltd. Phase IV of this study focuses on the performance of various exterior insulated residential wall assemblies in a high stress moisture environment. The following seven assemblies were installed on each cardinal orientation.
