2025 California WUI Code multipane tempered-glazing path

The 2025 California Wildland-Urban Interface Code includes a path for multilayered glazing with at least one tempered pane.

This record covers one prescriptive glazing path. Glass block, 20-minute glazing, and SFM 12-7A-2 tested assemblies are separate paths. The window schedule and the exact glazing option still need review by the building official.
