Product Quality
Quality in manufacturing and superior product performance is guaranteed with our regular and comprehensive testing program.
All our products are engineered and tested to comply with North American testing requirements, including NFRC and NAFS. These third-party laboratory tests are conducted on all our products to ensure they meet the code-required performance standards.
We also regularly conduct in-house testing in our state-of-the-art testing chamber; up to10% of our products are randomly selected and tested in our air and water testing chamber. The testing chamber is calibrated to meet ASTM specifications and allows us to test very large windows, doors, combinations of windows and doors, and entire wall mock-ups.
Regular on-site testing at various projects throughout the Pacific Northwest completes our rigorous testing program. These site tests, including site water testing and blower door tests, are important to ensure that all manufactured products perform as engineered when installed – the only true confirmation of actual performance.
