Single Skin Sandwich Roof Panels

Single Skin Sandwich Roof Panels


Pre-painted galvanized roofing sheets. In the past 20 years, end-users, contractors and consultants have become increasingly aware of the losses associated with thermal transmission. Insulation of various types is now used in all types of buildings. The insulated polyurethane sheets have a thickness of 20 mm. Liner panels have one metal skin surface with polystyrene foam board adhered to it for better insulation. Polyurethane has been recognized as the most resistant material to heat transmission.

Uses: These sheets can be successfully applied to cold storage, warehouses, residential villas, houses, covered pools and sports complexes. Moreover, there are various choices of rich colours available both in single skin or double skins.

The features include:

  • Resistant to corrosion, deformation and breaking
  • High resistance to water absorption
  • No requirements for interior or exterior finishing
  • Can simply be disassembled when necessary
  • High insulation value
  • Long service life
  • Strong aesthetic value
