Kingspan Insulation Thermal Conductivity

What is Thermal Conductivity?

The thermal conductivity of a product is its ability to conduct heat and is expressed in W/mK. It can also be known as a K value (λ) or lambda value. The lower the thermal conductivity, the better the product is to resist heat transfer.

What is the Thermal Conductivity of Kingspan Insulation?

Each range of Kingspan insulation has a different thermal conductivity. The lower the thermal conductivity, the better the insulator.
  • Kingspan OPTIM-R is a vacuum insulation panel (VIP) with a thermal conductivity of 0.007 W/mK.
  • Kingspan Kooltherm K100 is a range of phenolic insulation with a thermal conductivity of 0.018 W/mK.
  • Kingspan Kooltherm is a range of phenolic insulation with a thermal conductivity of 0.023 W/mK - 0.020 W/mK depending on the thickness of the product. 
    • 25 - 44 mm = 0.021W/mK
    • 45 mm or greater = 0.020W/mK
  • Kingspan Therma is a range of PIR insulation with a thermal conductivity of 0.022 W/mK.
  • Kingspan GreenGuard is a range of extruded polystyrene insulation (XPS) with a thermal conductivity of 0.034 W/mK.
  • Kingspan Aerobord is a range of expanded polystyrene insulation (EPS) with a thermal conductivity of 0.031 W/mK or 0.038 W/mK, depending on whether it's the platinum range or the standard range.
