A large-scale field monitoring study was implemented in the Lower Mainland of British Columbia with the intent of measuring the impacts and benefits of roof membrane color, and insulation strategy on the long-term thermal and hydrothermal behavior and performance of conventional roofing assemblies.
Three different 2-ply SBS roof membrane cap sheet colors were installed over three different insulation arrangements for a total of nine unique test roof assemblies, which were installed on an industrial building located in Chilliwack within the Lower Mainland of British Columbia, Canada. Chilliwack is located in ASHRAE Climate Zone 4 and has a climate similar to the larger nearby metropolis of Vancouver, though as it is farther inland, it typically gets hotter in the summer and colder in the winter.
