PU sandwich panels, consisting of 2 metal facings with a PU core, are produced in a variety of colours, profiles and sizes for wall, roof and garage doors. They can be adapted to almost all architectural and structural challenges. The physical properties of the rigid PU foam core and the tightness of the joint technique provide exceptional thermal performance, which is essential in the refrigeration and air-conditioning sector.
  • High insulation with reduced risk of air leakage
  • Reduced cold bridging
  • High durability
  • Low maintenance
  • Easy installation and efficient use of space
