Construction Efficiency

These 40mm Kooltherm floor insulation boards are exceptionally light in weight, streamlining transport, handling, and installation processes on-site.

The Facings

Manufactured at Kingspan Insulation in Pembridge, Herefordshire, the 40mm Kooltherm K103 incorporates glass tissue-based facing that is bonded to the insulation core throughout the manufacturing process. This protective facing is applied to both surfaces, providing a robust and long-lasting bond.

The Core

The 40mm Kingspan K103 Phenolic insulation core comprises a premium rigid thermoset phenolic material. This insulation is manufactured without fibres and utilises a blowing agent with zero Ozone Depletion Potential (ODP) and minimal Global Warming Potential (GWP). The outcome is a sustainable insulation product delivering exceptional thermal performance.
