As wildfires grow in frequency and severity across North America, building professionals face increasing pressure to design structures that are more likely to survive these extreme events— especially in Wildland-Urban Interface (WUI) zones. Windows are among the most vulnerable elements in the building envelope during a wildfire, often acting as failure points for heat, flame, and ember intrusion.

This webinar provides a focused exploration of strategies to enhance window wildfire resistance in fireprone environments. Attendees will be introduced to key performance considerations for window assemblies, covering fire exposure mechanisms, material behavior, and construction details that affect survival in WUI conditions. The session will include an in-depth review of California’s State Fire Marshal (SFM) Standard Test Method 12-7A-2, which governs exterior window performance in wildfire zones. In parallel, participants will explore emerging guidance from Canadian authorities, such as the National Guide for Wildland-Urban Interface (WUI) Fires and FireSmart Canada. Practical insights will be delivered through concept review, test data, and design strategies, equipping architects, engineers, and builders with the tools to select window systems that help resist structure ignition while maintaining compliance and performance.
