Wood is not a fallback or an exception there; it is one of the three named paths. Vehicle access doors are excepted from this section and are instead caught by the perimeter-gap rule in 404.9. This is the mirror image of Oregon barring wood shingle and shake roofs, and the pair is the point - \"no wood in the WUI\" is wrong in both directions, and what matters is which assembly, at which thickness, in which code.","asOf":"2026-08-29T00:00:00.000Z","scopeKind":"standard","scopeRef":"cwrc-2025","relatedCategories":["windows-doors"],"sources":[{"title":"2025 Colorado Wildfire Resiliency Code, Section 404.8","url":"https://dfpc.colorado.gov/colorado-wildfire-resiliency-code","publisher":"Colorado Division of Fire Prevention and Control","sourceType":"official","accessedOn":"2026-08-29T00:00:00.000Z","notes":"404.8 Exterior Doors.

Section 404.8 quoted verbatim in the source note. Deliberately paired with wood-shake-not-r327-roof-path, which is the same shape inverted; neither record says as much alone as the two do together."}}
