Fire rating

  • Our structural insulated panels meet the building regulations requirements with regard to fire resistance when lined with a conventional 15mm gypsum board.
  • Our SIPs have been tested and classified as an effective fire resistant element.
  • The PIR rigid foam core has reduced combustibility and higher working temperature limits compared to SIPs panels with a PUR core.
  • Rigid PIR is a thermoset foam designed not to melt, unlike thermoplastic EPS/PUR insulation foams.
