PRANCE metalwork is a leading manufacturer of metal ceiling and facade systems.
Optimizing airflow in a perforated aluminum panel system begins with selecting the right open-area ratio, typically between 20–40%, to balance ventilation with weather protection. The perforation pattern—round, slot, or custom CNC shapes—affects turbulence and laminar flow behind the facade. Installing the panels on a ventilated rainscreen sub-frame creates a continuous 25–50 mm cavity where air can circulate, flushing out moisture and heat. Inlets at the base and outlets at the top of the cavity use natural stack effect to drive passive airflow, reducing cooling loads and preventing condensation. Sealed perimeter trims prevent wind-driven rain ingress while maintaining the designed airflow path. For high-rise applications, pressure equalization chambers can be integrated to stabilize differential pressures across the panels. Together, these elements yield an aluminum facade that breathes efficiently, enhancing durability and indoor comfort.
