2025 California WUI Code SFM 12-7A-3 horizontal-underside path

The 2025 California Wildland-Urban Interface Code includes SFM Standard 12-7A-3 performance paths for boxed-in eave soffits and the undersides of floor projections.

A matching test protocol is product evidence only for the exact application in its listing. Eave versus projection geometry, complete assembly, installation, current listing status, local amendments, and approval remain checks.
