40mm Kingspan TF70 ThermaFloor PIR Insulation Board 2.4m x 1.2m

40mm marks the point where Kingspan Thermafloor® TF70 starts to make a real thermal difference rather than a token one. At 1.80 m²K/W thermal resistance and a 0.022 W/mK conductivity, this PIR board gives solid concrete and suspended timber floors a genuine upgrade while keeping the overall build-up compact. Both faces carry a low emissivity composite foil, and the board suits new build and renovation equally. A sensible first step up from the slimmer thicknesses.
