Kingspan Insulation has launched a new ultra-low lambda cavity board which offers a thermal conductivity of just 0.018 W/m.K. The BBA-certified Kingspan Kooltherm K106 and K108 cavity boards feature Kingspan’s fibre-free thermoset phenolic insulation core. This allows for a U-value of just 0.17 W/m2.K to be achieved, with an overall cavity of just 100mm in a standard masonry construction. The K106 cavity board can installed with a mere 10mm air gap instead of the standard 50m
