Fire-Rated Wood

Different Fire Rating Classes

Class A

Class A materials offer the highest level of fire resistance, with the lowest flame spread and smoke development. This rating is typically required in wildfire-prone areas.

Lowest flame spread
Meets most building code requirements
Ideal for WUI compliance
Recommended for maximum protection

Class B

Class A

Class B materials provide a moderate level of fire resistance. While they slow flame spread, they do not meet the same strict standards as Class A materials.

Medium flame spread
Suitable for some interior uses
Not typically approved for WUI zones

Class C

Class A

Class C

Class C materials offer basic fire resistance and allow for higher flame spread compared to Class A and B. These are generally used where fire protection requirements are minimal.

Highest flame spread
Limited fire resistance
Not suitable for high-risk areas
