Kingspan Insulation - Kooltherm Rigid Insulation for Roof Wall & Floor Applications | Thermal Insulation - Kingspan UK


Kingspan Group Kingspan Insulation


The Kooltherm K-range is an extensive range of premium performance rigid phenolic insulants for roof, wall and floor insulation. Kooltherm offers the following benefits:

  • With a thermal conductivity of 0.018–0.023 W/m.K these are the most thermally efficient insulation products commonly used.
  • The thinnest commonly used insulation products for any specific U–value.
  • Rigid thermoset phenolic insulation core is Class 0, as defined by the Building Regulations in England, Wales & Ireland, and Low Risk, as defined by the Building Standards in Scotland.
  • Rigid thermoset phenolic insulation core achieves the best possible rating of < 5% smoke obscuration when tested to BS 5111: Part 1: 1974.
  • Manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP).
  • Their closed cell structure resists both moisture and water vapour ingress – a problem which can be associated with open cell materials such as mineral fibre and which can result in reduced thermal performance.
  • Unaffected by air infiltration – a problem that can be experienced with mineral fibre and which can reduce thermal performance.
  • Safe and easy to install – fibre-free core.
  • If installed correctly, can provide reliable long term thermal performance over the lifetime of the building.
