The Kingspan Kooltherm product is a premium performance lower lambda insulation with a fibre-free rigid thermoset phenolic core. It is used for insulating beam and block, concrete, and timber floors.

There is nowhere in a residential building whereby Kingspan Insulation cannot be used and if you can, Kooltherm is the way to go.

The Kingspan Kooltherm product range offers a higher thermal resistance than your standard PIR insulation, with a thermal resistance of 0.020, this product is the architects choice product of excellence when specifying what product to use in certain applications.

However, the down side to this is the Kooltherm product is about 30% more expensive than standard Pir with only a 10% increase in thermal resistance. So this product is not always practical to use in residential homes due to its cost.

Where you see this product being used the most is in commercial buildings under construction, as this product will give a better performance while not compromising on space.

In commercial properties space is money so every m2 gained is money in the bank and Kingspan Kooltherm gives this option. Of course you will also see this product being used on oil rigs, hospitals, industrial buildings and many more as Kingspan Kooltherm offers a better fire resistance also than standard PIR.
