The Metalcraft Insulated Panel System is certified for use as either:

• a fully finished internal or external wall or
• a roof or wall cladding system

The Metalcraft Insulated Panel Systems comprise Thermospan and Thermopanel panels, and ancillary components such as angles, fixings and flashings. Thermospan and Thermopanel panels consists of steel facings laminated to a Class S (AS1366.3-1992) expanded EPS foam core. The steel facings are as follows:

• Thermospan – external steel facing is 0.59mm COLORSTEEL® MAXAM® G300 AM150 and the internal steel facing is 0.59mm COLORSTEEL® MAXAM®.
• Thermopanel – external and internal facings consist of 0.59mm CP Grade Pre-painted Galvanised Steel G300 Z275, or 0.59mm COLORSTEEL® MAXAM® G300 AM150 depending on application and environmental category.

The Metalcraft Insulated Panels are available in the following thicknesses (mm): 50, 75, 100, 150, 175, 200 and 250.
