Testing & Ratings

Our products consistently meet and exceed the highest recognized standards in the industry.

In addition to the comprehensive quality control program practiced in-house, Cascadia has retained expert external consultants (in both Canada and the US) to inspect and improve our products and our manufacturing process. We test our windows and doors to all required Canadian and American standards, including optional ratings such as Condensation Resistance. A minimum of 10% of the windows we manufacture for each project are selected at random and tested.

 

Testing for compliance with AAMA/WDMA/CSA 101/I.S.2/A440-08 (NAFS: North American Fenestration Standard/Specification for windows, doors, and skylights) is ongoing. Intertek Ltd. performs various tests on a regular basis (including ASTM E283, ASTM E331, and ASTM E330). Our NFRC (National Fenestration Ratings Council) listings and ENERGY STAR qualifications are overseen by Keystone Certifications Inc. 

 

Cascadia product testing often goes beyond the factory or laboratory: we also field test our sizeable projects. This rigorous testing process is part of our commitment to superior performance, ensuring that we are providing the best windows and doors on the market.
