We have recently made the transition from the old insulation standard AS 4859.1:2002 to the updated standard AS 4859.1:2018. The updated standard includes amendments to the way in which rigid foam insulation is aged tested and statistically averaged, the outcome of which is typically a derating of most insulations' R-Value, depending on the thickness, type and chemical composition of the insulation in question.

The Kingspan Kooltherm range is an extensive range of high performance rigid thermoset phenolic insulation for roofs, walls and floors.

Why Kingspan Kooltherm?

Kooltherm Thickness Comparison

The Kingspan Kooltherm Advantage

Kingspan Kooltherm offers among the most thermally efficient conductivity and thermal performance values available, which means you can minimise thickness of your insulation compared to other conventional insulations to achieve the same performance.

Kingspan Kooltherm also has exceptional fire performance characteristics. As it is a thermoset material it hardens and chars in fire situations, giving off very little smoke; unlike thermoplastics, such as polystyrene which melt, soften, and give off thick black smoke.
