140mm Kingspan TF70 ThermaFloor PIR Insulation Board 2.4m x 1.2m
Aimed at low-energy new build floors, 140mm Kingspan Thermafloor® TF70 reaches very low U-values from a single layer. Its 6.35 m²K/W thermal resistance, drawn from a 0.022 W/mK polyisocyanurate (PIR) core, holds across a wide span of floor perimeter-to-area ratios. Composite foil faces both sides, and the board works in solid concrete and suspended timber construction. A near-top thickness for projects driving down whole-building heat loss.
Benefits
- Thermal resistance of 6.35 m²K/W
- Reaches very low U-values from a single layer
- PIR core rated 0.022 W/mK
- Composite foil facing to each face
- Across new build and renovation projects
- Compressive strength 120 kPa at 10% compression
- Light and manageable to install
Good to know
- Good water vapour resistance
- 2400mm x 1200mm sheets, 2.88m² each
- BBA 14/5133 certification, 20 to 150mm
- Keep dry: store flat, raised and covered
