What’s the ideal panel thickness for wind load resistance?

Determining ideal panel thickness for wind load involves balancing strength, weight, and cost. For low- to mid-rise buildings in moderate wind zones, 3 mm to 4 mm thick solid aluminum or composite panels often suffice when anchored with robust subframes. In high-wind regions or on tall facades, 5 mm to 6 mm panels or thicker ACPs with reinforced cores provide additional stiffness and resistance to deflection. Engineers calculate local wind pressures—considering building height, exposure category, and terrain—and specify thickness accordingly. Panel size and aspect ratio also influence performance: smaller panels reduce acting force and may allow thinner gauges. Collaborative design between structural and façade teams ensures panel thickness matches wind-load requirements without over-engineering or excessive weight on the supporting structure.
