Applications
Insulated Metal Panels (IMPs)

Insulated Metal Panels (IMPs) have a rigid methylene diphenyl diisocyanate (MDI)-based polyurethane foam core "sandwiched" between two metal facings. Panels are factory produced on a continuous lamination basis with metal facings – usually steel– encapsulating a foamed PUR or PIR core. The thickness of the polyurethane foam can range from 30mm to 240mm depending upon application and required insulation characteristics. These versatile products are also known as sandwich panels.


In Europe, DaltoPUR® and DaltoPIR® insulation foam from Huntsman has been designed to improve the manufacture of the panel and has achieved the following fire resistance classifications, according to European Standard EN 13501-2:

  • EI 30 for 100 mm wall panels (EN 1364-1)
  • REI 30 for 100 mm roof panels (EN 1365-2)

Versatile Applications

Because of their high thermal insulation values, ease of use, high degree of stability and rigidity, IMPs are used in a diverse range of applications such as:

  • Commercial and industrial buildings
  • Self-supporting roofs and walls
  • Commercial and residential entry and garage door panels
  • Commercial refrigeration
  • Refrigerated transport vehicles
