  • Polyurethane (PUR)
    Rigid polyurethane {PUR) materials are cellular thermosetting insulation materials providing very high degree of thermal insulation compared to other construction materials.
  • Polyisocyanurate (PIR)
    Rigid Polyisocyanurate {PIR) insulation materials are extensively modified polyurethane through the incorporation of the much great heat resistant isocyanurate, accordingly sandwich panel with PIR foam will give better reaction to fire


  • Polyisocyanurate foams, referred to as PIR, is essentially modified polyurethane (PU) foam.
  • Two advantages of PIR foam are improved fire-resistance and excellent insulation & machanical properties.
  • The proportion of MDI is higher than for PUR. As a result the MDI will also react with itself, producing strong chains of isocyanurate.
  • These chains are stronger than normal bonds in polyurethane and results in a chemically and thermally more stable foam
  • Superior R-Value and thermal performance.
  • Moisture resistance.
  • Dimensionally stable.
  • Excellent fire test performance.
  • Unaffected by commonly used construction adhesives and solvents.
