Beauty of Redwood

Class A Flame Rating

Sustainable

Irresistible Appeal

Now even in wildfire-prone communities, builders can feature redwood’s exceptional charm and strength with the reassurance of a Class A flame spread rating.

Ideal for WUI Communities

Redwood is a highly attractive, premium choice for decking and siding. ExteriorFireX™ treatment finishes clear to preserve redwood’s natural beauty while addressing WUI code requirements that demand fire-retardant-treated wood be pressure-impregnated, not merely coated. The Class A flame spread rating means the treated redwood can better withstand direct flame exposure and resist ignition, so it won’t significantly contribute to wildfire spread.

Independently Verified

Exterior materials in WUI zones are required to pass ASTM E84 (UL 723) surface burning testing, typically conducted for 30-minute durations vs. the standard 10 minutes for interior materials. Hoover/Humboldt products are code compliant with the 2025 California Wildland-Urban Interface Code (CWUIC).

Locally Harvested. Sustainably Treated.

Humboldt’s Forest Stewardship Council® (FSC® C013133) certified timberlands and sustainable forestry practices ensure long-term forest health and carbon sequestration. Locally harvested and milled redwood reduces environmental impact compared to imported alternatives.
