Meeting the Canadian Standards: What You Need to Know

27 June 2025

In today's dynamic construction environment, building codes and product standards are continuously evolving. For window manufacturers, these changes represent not only challenges but opportunities to lead the industry. At INTUS Windows, we proactively embrace these evolving standards, ensuring our window systems consistently meet and exceed both local and international expectations.

In North America, window performance is governed by the North American Fenestration Standard (NAFS), also known as AAMA/WDMA/CSA 101/I.S.2/A440. This joint standard, developed by the Fenestration & Glazing Industry Alliance (FGIA), the Window & Door Manufacturers Association (WDMA), and the Canadian Standards Association (CSA), applies to both new construction and replacement projects across North America.

At INTUS Windows, every window system we manufacture is rigorously tested by certified laboratories in accordance with this standard. Our internal research and close collaboration with our testing partners confirm that the key performance criteria – operating force, air infiltration, and water penetration resistance – are aligned with U.S. requirements.

A Key Difference: Water Drainage in Canada

One specific Canadian requirement sets itself apart: no water should remain trapped within the window system after testing. We carefully validated this with our independent lab, and we’re proud to report that all INTUS window systems pass this test with flying colors. Our products are fully compliant, ensuring long-term durability and performance for Canadian builders, architects, and homeowners.

Energy Performance That Crosses Borders

Energy efficiency doesn’t stop at the border. In Canada, NFRC (National Fenestration Rating Council) certification is widely recognized and accepted for energy performance evaluation, even though it is a U.S.-based system. NFRC labels transparently communicate essential thermal performance metrics, including:

  • U-Factor (rate of heat transfer)

  • Solar Heat Gain Coefficient (SHGC)

  • Visible Transmittance (VT)

  • Air Leakage (AL)

When temporary NFRC labels are used in Canada, they must display both “C” (Canada) and “US” (United States) identifiers, as required by the Canadian Building Code. All INTUS windows are fully prepared to meet this dual-market requirement. Our labels are always properly formatted, fully certified, and ready for seamless acceptance in both countries.

Certified. Compliant. Canada-Ready.

INTUS Windows products are built to meet the highest standards of performance, energy efficiency, and durability.

✅ Fully compliant with AAMA/WDMA/CSA 101/I.S.2/A440 (NAFS)
