The core of Kingspan Kooltherm Insulation Board is a premium performance rigid thermoset fiber–free phenolic insulant manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP).

When installed correctly, Kooltherm can provide reliable long term thermal performance over the lifetime of the building.
