Certifed fire-rated suspension systems use galvanized steel grids with fusible links or fire rods, engineered to collapse and seal plenum openings at target temperatures.
Check for manufacturer test reports (ASTM E119/UL 263 or EN 1364-2), labeled components, installation guides, and third-party certification markings on packaging and submittal documents.
Acoustic insulation in aluminum ceilings—mineral wool or fiberglass—doubles as a thermal barrier, complementing fire-rated assemblies when tested together.
Fire-rated ceilings integrate tested assemblies—panels, insulation, sealants, and suspension systems—to satisfy local and international building codes for fire safety.
Properly engineered aluminum ceiling systems—with intumescent layers, insulation, and tested suspension hardware—can achieve both 1-hour and 2-hour fire ratings.
Perforated aluminum panels can be integrated into fire-rated ceilings when paired with suitable intumescent backing, insulation, and tested as part of a complete assembly.
