This is the cladding type, performed with aluminum composite panel that consists of two thin aluminium sheets binded to a non-aluminium core widely used for external facades of the buildings. The core is commonly low density polyethylene or a mix of low density polyethylene and mineral material to exhibit fire retardant properties. It can be coated with PVDF or Polyester paint in wide range of metallic or non-metallic colours as well as patterns that imitate natural materials like wood, marble etc. It is very rigid and strong despite its light weight.
