Specification notes

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.
The Class A statement applies to the listed fluid-applied system, including coat count and coverage. A maintenance application only retains the classification of the existing classified roof.
The live BML row refers to the UL Roofing Materials and Systems Directory but does not name a test protocol. Confirm the current classified system and substrate before specification.
