OSFM category 4175 is a general fire-rated roof covering listing, not the WUI-specific 8180 series. Confirm WUI applicability with the authority having jurisdiction.
Class A applies to the documented complete roof-panel configuration, not an isolated FRP skin. Match the Type A or Type SW-C face sheets, interior face, grid core, panel thickness, framing, supports, slope, fasteners, sealants, labeling, and installation conditions to the current report.
ESR-2464 requires the Type A and Type SW-C Class A panels to carry the UL listing mark on both interior and exterior facings. Verify the supplied labels before specification.
OSFM listing is not a permit. The authority having jurisdiction decides.
