Aluminum Composite Material

ACM, a composite of two thin sheets of aluminum sandwiching a thermoplastic core.  This gives the panel the highest rigidity to weight ration possible in a metal facade.  This allows the panel to have excellent mechanical properties at a lower weight than the alternatives.  Benefits of using an ACM system include:

Fire resistant
Weather and chemical resistant
Added thermal and noise insulation
Rigid yet formable
Cost effective for given density
