Kingspan Kooltherm

About

Kingspan Kooltherm is a range of fibre-free rigid thermoset phenolic insulation boards, widely regarded as one of the highest-performing rigid insulation options available in the UK market. With lambda values as low as 0.018 W/mK on selected boards, Kooltherm delivers exceptional thermal performance in thinner profiles than most alternative board types, making it a preferred specification wherever space is limited and U-value targets are demanding. All boards are CFC and HCFC-free with a low global warming potential, and the range spans application-specific products covering floors, walls, roofs, soffits and framing systems. Kooltherm Board Types Each board in the Kooltherm range is engineered to the specific performance and installation requirements of its intended application, with distinct facings, thermal conductivity values and compressive strengths suited to the demands of each build element.

Available from 25mm to 150mm, it is widely specified across both new build and retrofit projects. K106 Cavity Wall Board The Kooltherm K106 is a full-fill cavity wall board for masonry construction, with a water-tight, vapour-open polypropylene fleece outer facing to protect against moisture penetration and a low emissivity composite foil inner facing.
