Inorganic Insulation Materials

As can be seen from the figure, inorganic materials can be classified accordingly:

• Fibrous materials
  • Glass wool
  • Rock wool
• Cellular materials
  • Calcium silicate
  • Cellular glass

Organic insulation materials can be classified accordingly:

• Petrochemical materials (oil/coal derived)
  • Expanded polystyrene (EPS)
  • Extruded polystyrene (XPS)
  • Polyurethane (PUR)
  • Phenolic foam
  • Polyisocyanurate foam (PIR)
• Renewable materials (plant/animal derived)
  • Cellulose
  • Cork
  • Woodfibre
  • Hemp fibre
  • Flax wool
  • Sheeps wool
  • Cotton insulation
