How does ACP cladding’s fire rating differ from wood panel systems?

Fire safety is a critical consideration in facade and ceiling design, and aluminum composite panel (ACP) cladding offers enhanced performance over traditional wood panel systems. Standard ACP panels often use a polyethylene core that is combustible; however, fire-rated ACP variants incorporate a mineral-filled core—such as hydrated magnesium carbonate—that achieves non-combustible classifications per EN 13501-1 (Class A2) or NFPA 285 compliance in the U.S. These fire-retardant cores resist flame spread and limit smoke development, providing critical fire containment in building envelopes. Combustible wood panel systems, including solid timber or engineered wood veneers, ignite readily and contribute fuel load, potentially accelerating fire propagation. Even treated or fire-retardant-impregnated wood requires thicker laminates and specialized coatings to meet the same ratings, adding cost and installation complexity. Additionally, ACP’s aluminum skins act as a heat-dissipating barrier, while wood surfaces char and degrade structurally. For aluminum ceiling installations, fire-rated ACP panels maintain integrity under high temperatures and can be integrated with sprinkler and smoke control systems. Overall, fire-rated ACP cladding provides a safer, code-compliant solution compared to conventional wood panel facades and ceilings.
