Kooltherm® K10 FM Soffit Board header

Kingspan Kooltherm K10 FM Soffit Board is a premium performance insulation with a fiber-free rigid thermoset phenolic core, a glass tissue based facing on its front surface and low emissivity composite foil on its reverse surface which is used for structural ceilings. It is resistant to the passage of water vapor, unaffected by air infiltration, and provides a higher R-value per inch than any commonly used insulation.

The core of Kingspan Kooltherm® K10 FM Soffit 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).
