TimberTech EDGE Premier Square Edge decking is the product covered by AZEK's California wildfire-area listing 8110-2042:0500.

Board spacing is part of that description: the composite boards measure 0.89 by 5.36 inches and require a 1/8-inch edge-to-edge gap. They serve as the deck surface. Category 8110, SFM 12-7A-4A, and Class B flame spread appear in the listing; the manufacturer's instructions and product data sheets supply the installation guidance.

OSFM includes EDGE Premier Square Edge in the WUI handbook's September 2, 2025 edition. The live BML observation dated August 25, 2026 showed an active listing with a June 30, 2027 expiration. Match the EDGE Premier Square Edge model, dimensions, and gap to that entry, and confirm current GOVmotus status before specifying the decking.
