75mm Kingspan TF70 ThermaFloor PIR Insulation Board 2.4m x 1.2m

Keeping thermal mass low is the trick behind fast-responding underfloor heating, and 75mm Kingspan Thermafloor® TF70 is often set below the screed to do exactly that. Positioned above the slab, it lets an intermittent heating cycle warm up quickly, while its 3.40 m²K/W thermal resistance holds performance. The 0.022 W/mK PIR core carries low emissivity foil on both sides and works in solid concrete and suspended timber floors alike. A strong option where heating response matters as much as insulation.
