Aluminum Composite Panel

Aluminum Composite Panel

An aluminum Composite Panel (ACP) is a three-layer sandwich panel consisting of two pre-painted aluminum sheets bonded to a polyethylene (PE) core. It is widely applied to a building’s curtain walls, exterior cladding, decoration panels... It can be compatible with CAS self-designed facade system, and make a complete exterior facade system with excellent thermal insulation and well-performed air and water tightness.
