Colorado CWRC Class 2 wall-base protection path

The 2025 Colorado Wildfire Resiliency Code specifies a six-inch vertical metal or noncombustible detail between wall sheathing and cladding at ground, deck, and roof intersections.

A product can document role, height, and material only. Continuity, drainage, intersections, fastening, mapped class, and the adopted local detail remain project checks.
