Construction Efficiency

These 25mm Kooltherm floor insulation boards feature a lightweight construction that streamlines transportation, handling, and on-site installation.

The Facings

Manufactured at Kingspan Insulation in Pembridge, Herefordshire, the 25mm Kooltherm K103 incorporates a glass tissue-based facing that is permanently bonded to the core during production. This protective facing is applied to both surfaces, ensuring robust and long-lasting performance.

The Core

The 25mm Kingspan K103 Phenolic insulation features a premium-grade rigid thermoset phenolic core. This material contains no fibres and is manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and minimal Global Warming Potential (GWP). The result is an environmentally responsible insulation product delivering exceptional thermal performance.
