Yes, EverGrain square- and grooved-edge composite deck board is listed for wildfire-area use as WUI decking.
The CAL FIRE OSFM listing, 8110-2044:0001, covers EverGrain composite deck boards measuring 13/16 inch thick and 5.5 inches wide. The 2025 OSFM WUI handbook records SFM 12-7A-4A and Class C flame spread. The live Building Materials Listing recorded the product as listed on August 25, 2026; its stated expiry is June 30, 2027.
The board serves as the deck surface under the listing, which requires the attached exterior wall covering to be noncombustible or ignition-resistant material. The listing therefore applies to the specified board and construction condition, not every product sold under the EverGrain name. Before specifying it, confirm the live listing and match the exact model, dimensions, and required wall covering to the planned deck.
