Construction Efficiency

100mm Kooltherm floor insulation boards feature a lightweight design that streamlines transport, handling, and installation processes on any project.

The Facings

100mm Kingspan Kooltherm K103, produced at Kingspan Insulation in Pembridge, Herefordshire, incorporates glass tissue-based facing bonded to the insulation core during manufacturing. This facing is applied to both surfaces of the board, providing a robust and long-lasting bond.

The Core

100mm Kingspan K103 Phenolic insulation utilises a premium rigid thermoset phenolic core. The material is fibre-free and manufactured with a blowing agent featuring zero Ozone Depletion Potential (ODP) and minimal Global Warming Potential (GWP). This results in an environmentally responsible insulation product delivering outstanding thermal performance.
