Foam systems can be blown with water (CO2), 245fa, 365/227blends, Pentane or Ecomate. Ecomate systems, available from Australian Urethane & Styrene , are an ideal family of polyurethane foam systems.

The Ecomate foam system demonstrates advanced characteristics to meet current and future market needs.

Ecomate rigid foam systems exhibit:

  • Zero ozone depletion potential
  • A blowing agent with zero global warming potential
  • The thermal efficiencies the market is accustomed to


  • The lower the thermal conductivity or K value, the better the insulation
  • Water blown systems have higher thermal conductivity (less insulation)
  • Water blown foams achieve 0.032 W/m.K.
  • 245fa systems have vapour pressure problems; water is added to reduce this, resulting in higher thermal conductivity (less insulation)
  • Ecomate and 141b foam systems achieve 0.020 to 0.022 W/m.K
  • 141b is an ozone depleting chemical.
