In order to offer our customers a Class A flame-spread rated exterior fire retardant decking product, Allweather Wood works with Chemco, Inc. of Ferndale, Washington to pressure treat Humboldt Sawmill Superior Common redwood decking with Thermex-FR®. The result is Humboldt Sawmill Class A Exterior redwood decking. This product is covered by a Limited Lifetime Warranty. In addition to decking, accessory items such as joists, railings, and other specialty items are available.

Class A flame-spread rating means this product can be used under even the most stringent Wildland-Urban Interface (WUI) building codes throughout the country, including the International Code Council® International Wildland-Urban Interface Code (IWUIC). The IWUIC code requires decks to be constructed of approved fire retardant treated wood specified for exterior use. Under such guidelines, only a Class A flame-spread rated exterior wood product would qualify for usage.
