Can aluminum façade panels be fire-rated for high-rise use?

Yes—aluminum façade panels can be engineered for fire-rated applications on high-rise structures by using non-combustible mineral cores instead of traditional polyethylene. Mineral-filled aluminum composite panels (ACPs) incorporate a fire-resistant core composed of inorganic materials like magnesium hydroxide, achieving Class A ratings under ASTM E84 and EN 13501-1. These panels undergo rigorous fire testing, demonstrating limited flame spread, negligible smoke development, and no sustained burning when exposed to heat sources. Installers must follow manufacturer fire-stop instructions: continuous cavity barriers, compliant joint systems, and adequate airflow separation. When properly specified and certified, fire-rated aluminum façades deliver the sleek modern look architects desire while adhering to stringent high-rise fire-safety codes and protecting occupants.
