Kingspan Kooltherm K108
Premium performance rigid Phenolic partial-fill cavity wall insulation board
Replaces Kingspan Kooltherm K8.
New lower Lambda Value (Thermal Conductivity) 0.018 W/mK... The most thermally efficient commonly used insulating board.
Low emissivity foil facings significantly increase the thermal performance of the cavity.
Boards are designed to fit easily with standard brick and block dimensions allow the insertion of wall ties at appropriate spacing.
Premium performance rigid thermoset fibre-free phenolic insulant manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP).
Unaffected by air infiltration. Resists moisture penetration by allowing a clear cavity to be maintained.
