Insulated Panel Face Materials

The facings or skins of composite panels are typically metallic coated, pre-painted steel or aluminium, and are either profiled or flat on either or both sides of the panel. The internal skin is also known as the liner skin or sheeting.

The metal facing is commonly made from grade G300 steel of 0.40 – 0.63 BMT thickness, with a pre-painted organic finish over a metallic coating. Cool room panels have a galvanised Z275 metallic coating, while interior/exterior structural insulated panels have an aluminium/zinc coating of AZ150 or AZ200. Paint coatings are specifically developed to assist in bonding the insulation to the panel

Aluminium facings are used in very humid conditions or severe marine environments and can be supplied plain or pre-painted.
