Shakertown Craftsman one-course cedar shingle panels
This is a listed siding assembly. Listing 8140-2032:0001. This site cites cal-fire-bml. Match the model and orientation. A listing is not a permit.
Shakertown Craftsman panels are eight-foot, one-course siding panels made from clear vertical-grain Western red cedar in 4.5-, 7-, and 14-inch exposures. Current CAL FIRE OSFM listings 8140-2032:0001 and 8140-2032:0002 cover horizontal wall installations over specified OSB sheathing; the two listings describe different plywood-backed and exposure configurations.

Listing 8140-2032:0001 requires a plywood-backed panel, 3/8-inch shingle butt, overlapping end joints, minimum 7/16-inch OSB, and No. 15 building paper. Listing 8140-2032:0002 has a distinct exposure-based design. Match the selected panel to the exact current OSFM sheet.
Both OSFM listings are horizontal-only. Manufacturer literature for other Craftsman products or assemblies does not expand the listed scope.
Shakertown's product page separately states Class B and ASTM E2707 performance, but the current OSFM sheets state Chapter 7A compliance without naming a test protocol. Obtain the applicable test report before treating that manufacturer statement as the listing basis.
