Course Description: Cascadia Windows: Wildfire Resistance: Window Strategies for Wildland-Urban Interface (WUI) Design
June 15, 2026 - 4:00pm - June 15, 2026 - 5:00pm
As wildfires increase across North America, architects, engineers, and builders must design buildings better able to withstand fire exposure, especially in Wildland-Urban Interface (WUI) zones. Windows are among the most vulnerable points in the building envelope, but thoughtful design and product selection can make them a critical line of defense. This session explores window wildfire-resistance strategies, including fire exposure mechanisms, material behavior, construction details, and system integration.
Through case studies, test data, and performance comparisons, attendees will gain insight into U.S. and Canadian wildfire-resistance guidance, including California SFM Standard Test Method 12-7A-2 and FireSmart Canada recommendations, along with strategies to reduce ignition risk and improve building survivability.
1. Understand how radiant heat, flame contact, and windborne embers impact window performance in WUI zones.
2. Examine how guidance from the National Guide for Wildland-Urban Interface (WUI) Fires and FireSmart Canada inform fire-resistant window selection in Canadian jurisdictions.
3. Gain familiarity with the test methodology for evaluating flame exposure resistance and performance metrics for exterior window units.
4. Compare different frame materials, glass types, and protective systems to determine their efficacy under fire exposure.
5. Understand options when specifying and detailing windows as part of a broader wildfire-resistant building envelope, balancing code compliance and thermal performance.
