What are the key fire safety features of aluminum wall panels?
Fire safety is paramount for building envelopes, and aluminum wall panels can meet stringent regulations when specified correctly. Select panels with non-combustible mineral-filled or fire-rated cores rather than standard polyethylene cores. Ensure that the panel system carries a Class A fire rating per ASTM E84, indicating limited flame spread and smoke development. Factory-applied intumescent sealants at panel joints will expand under heat, sealing gaps to contain fire. Integrating a ventilated air cavity also prevents chimney-effect fire spread behind the cladding. All attachment hardware and insulation must comply with fire-performance codes, and continuous vertical joint barriers can be introduced at floor lines. With these measures, aluminum facades and suspended ceiling perimeters maintain compartmentation and occupant safety in compliance with global standards.
