What are the fire safety considerations for aluminum ACP in facades?
Ensuring fire safety compliance is paramount when specifying aluminum composite panels (ACP) for curtain walls and façade systems. The core material choice is the first critical decision: non-combustible mineral-filled cores (Euroclass A2, s1, d0) or specially formulated fire-retardant polyethylene cores can provide varying degrees of flame resistance and smoke control. It is essential to verify that the chosen panels carry relevant certifications—such as EN 13501-1 for Europe, ASTM E84 and NFPA 285 for North America—within the context of the complete façade assembly, including subframe, insulation, and sealants. Proper integration of cavity barriers and intumescent fire stops within rainscreen cavities prevents vertical fire spread behind the ACP cladding. Fire-rated sealants and backer rods in joint systems maintain compartmentalization under heat exposure, while tested anchor and clip designs ensure fastener integrity during thermal events. Finally, specifying third-party tested and approved ACP façade systems as a cohesive unit—instead of relying on isolated component ratings—provides the highest assurance of performance. For aluminum ceiling and facade specialists, adhering to these fire safety considerations safeguards building occupants and ensures regulatory compliance.
