Kooltherm is a range of premium performance thermal insulation boards for roof, wall and floor applications. It comprises the thinnest commonly used insulation products for any specific U-value.
With a fibre-free rigid thermoset phenolic core and a thermal conductivity of 0.019 - 0.022 W/mK, these are the most thermally efficient insulation products commonly used.
Part of the Kooltherm range is our 100 series. It has an even better thermal performance than the first generation, which means you'll either benefit from reduced heating and cooling demand or create more space with thinner boards.
We’re constantly working to further develop our product ranges, ensuring customers can achieve the performance they need with the slimmest possible thickness of insulation, regardless of the application.
