The National Research Council (NRC) Canada has announced the publication of a new performance-based standard, CSA A123.26-2021, Performance Requirements for Climate Resilience of Low Slope Membrane Roofing Systems. CSA A123.26 was published by the Canadian Standards Association (CSA) Group and is intended to be used by building designers, building owners, building code officials, product manufacturers, and installers. The project was partially funded by the RCI Foundation Canada.

“This is important research for the building enclosure industry here in Canada, and the Foundation is glad to have been a financial supporter of this project,” said Albert Duwyn, chair of RCI Foundation Canada. “There have been so many collaborators in this project, and we hope IIBEC members will benefit from this new information.”
The objective of CSA A123.26 is to provide additional requirements for climate adaptation in specified Canadian climatic zones for respective climatic loads. It also standardizes quality assurance requirements for installation, including requiring registered observers on projects.

Adds IIBEC President Ted Sheridan, “In particular, the field wind uplift testing protocol seems to have great potential as the basis for a field uplift testing standard.”
