Nusku Thermacor thermally modified ash decking is listed with a maximum edge gap and an attached-wall condition.

CAL FIRE number 8110-2064:0500 describes nominal 5/4-by-6-inch material. Its 3/16-inch maximum edge-to-edge spacing is a limit, not a requirement to leave a gap of exactly that size. Keep the Thermacor product identity with both the nominal dimensions and the spacing instruction.

The source names SFM 12-7A-4A but states that ASTM E84 was not conducted. It therefore supplies no ASTM E84 flame-spread class for the ash boards. The attached exterior wall covering must be noncombustible or ignition-resistant.

When reviewing the deck, check that adjoining wall covering alongside the board layout. Nusku's installation instructions and product data sheets provide the construction guidance referenced by OSFM. Confirm the exact Thermacor listing through GOVmotus before treating the nominal ash-board description as a complete specification.
