25mm Kingspan TF70 ThermaFloor PIR Insulation Board 2.4m x 1.2m
25mm Kingspan Thermafloor® TF70 does two jobs: it delivers a thin thermal upgrade across a floor, and it meets the minimum 25mm thickness Kingspan sets for the perimeter upstand strip that cuts cold bridging at the floor edge. That makes it a board many installers keep on hand even when a deeper thickness covers the main area. The rigid PIR core is rated at 0.022 W/mK and gives 1.10 m²K/W of thermal resistance, with composite foil top and bottom. A slim, dual-purpose option for solid and suspended ground floors.
Benefits
- Thermal resistance of 1.10 m²K/W
- Meets the minimum 25mm perimeter upstand thickness
- 0.022 W/mK lambda value
- Composite foil facing to the top and bottom faces
- For both new construction and renovation
- 120 kPa compressive stress at 10% compression
- Cuts, handles and installs easily
Good to know
- Offers resistance to water vapour
- Board size 2400mm x 1200mm, 2.88m² per sheet
- BBA Certificate 14/5133 applies across 20 to 150mm
- Keep boards flat, raised off the ground and covered
