TimberTech Pro Reserve Grooved decking has a wildfire-area listing that limits the board gap and specifies framing and wall-covering conditions.
Its 8110-2042:0502 entry covers composite material measuring 0.938 by 5.36 inches. Edge-to-edge spacing must be at least 1/8 inch and no more than 3/16 inch. Both ends of that range belong to the grooved profile's assembly; the listing does not give an unrestricted gap choice.
For support, OSFM describes Douglas fir joists of nominal 2-by-6-inch size at 16-inch centers. The boards attach to that framing. The rating printed alongside the construction is Class C flame spread, with SFM 12-7A-4A identified as the test protocol. An attached exterior wall must have noncombustible or ignition-resistant covering.
When comparing grooved decking, keep the permitted gap range with the board dimensions and joist layout. A matching collection name is only the beginning of that check. Verify the exact Grooved product in GOVmotus, then follow its manufacturer installation instructions and data sheets. Those documents complete the installation detail while the listing identifies the assembly and its attached-wall condition.
