At-a-glance signals
Lightweight, stiff aluminium composite facade panels with mineral-filled cores, suitable for rainscreen cladding and architectural features.
Overview
Executive summary
Aluminium composite panels (ACP) consist of two thin aluminium cover sheets bonded to a mineral-filled core. They offer high stiffness at low weight, good formability, and durable coil-coated finishes for facade cladding.
