MoistureShield Vision decking is listed for wildfire-area use with a maximum board-spacing limit and an attached-wall requirement.
The 8110-2321:0500 description gives the composite material's dimensions as 1 by 5.4 inches. It places the boards on nominal 2-by-6-inch Douglas fir joists at 16 inches on center and limits spacing to a maximum of 1/8 inch. Those are the dimensions and framing conditions to match for Vision.
OSFM identifies SFM 12-7A-4A as the test protocol. ASTM E84 was not conducted, and the attached exterior wall covering must be noncombustible or ignition-resistant. The listing therefore supplies no ASTM E84 flame-spread class for a comparison with another deck product.
Retain the wall-covering condition alongside the joist layout and maximum gap when reviewing the installation. Check the exact Vision model in GOVmotus and follow its manufacturer installation instructions and product data sheets. The assembly being cited is more specific than the MoistureShield brand name: it combines the named board, its stated dimensions and the surrounding construction.
