James Hardie's Cempanel is listed for wildfire-area walls as 5/16-inch fiber-cement vertical siding.
The product identified by OSFM listing 8140-2026:0003 is Cempanel. Both the thickness and the vertical application appear in its design description. Keep those details on the order and in the wall specification; a company name or a general fiber-cement description does not identify this particular siding.
The handbook places Cempanel in the exterior-wall siding and sheathing category. That is the application being cited. The remaining installation details belong in the manufacturer's product data sheets and instructions, which OSFM asks the specifier to consult.
Use that documentation to check the proposed Cempanel wall, and confirm listing 8140-2026:0003 in GOVmotus before relying on it. The listing gives the purchaser a specific vertical siding to verify. It does not make every James Hardie panel, profile or installation arrangement interchangeable with Cempanel.
