Fire Rating

When requested, all components in our products are fabricated using Class A materials. Individual wood members, panels, components and/or scrims are either naturally inert (metal, fiberglass) or treated with Class A Fire Retardant chemicals. These chemicals are applied either as FR coatings (solid wood), FR mixtures during fabrication (fiberboards and scrims) or FR impregnations after fabrication (FR plywoods). Finish coatings meet Class A when tested per ASTM E-84.

9Wood uses no PBDE FR chemicals. ASTM E-84 submittal data is based on supplier tests. Product assembly testing has not been completed since results vary on a project-by-project basis. To increase certainty of meeting today's fire marshal requirements, 9Wood recommends sprinkling both the ceiling and the plenum (concealed space).
