Polyisocyanurate Insulation Blocks (PIR)

General Information

Material: PIR (Polyisocyanurate) is a similar material to PUR. Both PUR and
Density: PIR are manufactured from the two components isocyanate and polyol. PIR has superior thermal resistance and dimensional stability. PIR is an improvement of previously used PUR boards (polyurethane).
Service: 

  • PIR (Polyisocyanurate) is suitable for all pipeworks of temperatures -150°C to +130°C
  • It has low density but high insulating properties
  • This product has the lowest thermal permeability compared to other insulation materials
  • Prevents the thermal losses in hot or cold pipework
  • Long life insulating material
  • Easy to application

Material: 

  • Complies with ASTM C 591
  • 80 kg/m³ acc. to ASTM C 591 120 kg/m³ acc. to ASTM C 591 200 kg/m³ acc. to ASTM C 591
