For a steel structure building, there are two scheme of the cladding for this building, insulation material(sandwich panel) or not insulation(single steel sheet), the final decision of the cladding material depond on the main purpose of the building.
Insulation helps maintain a comfortable interior temperature by keeping warm air in your building during the winter and conversely by keeping warm air out during the summer months. More importantly, steel building insulation creates a barrier throughout the roof and walls of your building, which prevents condensation.
insulation material: EPS/rock wool/glass wool/PU sandwich panel, ALC panel, cement foam board
not insulation material: color steel sheet
Considering of saving cost, the roof and wall can be used color steel sheet with glass blanket. it is cheaper than sandwich panel.
