What Panel Thickness Is Recommended for High-Rise Façades?

High-rise building facades demand panels that withstand significant wind pressures and structural movement. For solid aluminum cladding, a thickness of 3–5 mm is recommended to prevent undue deflection and noise under wind loads. When using ACM panels, choose aluminum skins of 0.5–0.7 mm bonded to a 3–4 mm mineral core, achieving a total thickness of 4–6 mm. Mineral-filled cores enhance fire performance for tall structures. The thickness selection balances weight and rigidity; heavier panels increase structural demands, while thinner panels risk flutter under dynamic loads. Panels must integrate with engineered sub-frames—aluminum or stainless-steel rails with adjustable brackets—to accommodate building sway and thermal expansion. Finite element analysis verifies panel behavior under design wind loads, ensuring deflection remains within L/180 to L/240 limits. By following these guidelines, architects ensure high-rise facades remain safe, stable, and visually consistent over the building’s lifespan.
