Engineered with precision, Kingspan Kooltherm K106 boasts a 10mm residual cavity and an ultra-low thermal conductivity of 0.019 W/mK. With its innovative design, Kooltherm K106 achieves impressive U-values with a thinner profile compared to alternatives. 

The Kooltherm K106 cavity board features a robust fibre-free rigid thermoset phenolic core, with a water-tight, vapour-open polypropylene fleece outer facing. This dual-layered shield safeguards against moisture ingress and also ensures optimal thermal efficiency. The inclusion of a low emissivity composite foil further enhances the material’s insulating properties, working to reduce thermal bridging and enhancing energy savings. 

Specially tailored for hassle-free installation, the unventilated design of the Kingspan Kooltherm K106 cavity board ensures lightweight handling and superior performance. Approved by NHBC for a 10mm residual cavity width, except for specific fairfaced masonry applications, Kooltherm K106 delivers unmatched thermal efficiency, durability, and reliability for your projects.
