Please note that the Kingspan Therma Pir Insulation products (TF70, TP10, and TW55) are an identical product, marketed under different names for use in floors, roofs, and walls respectively.

Kingspan Thermafloor TF70 is a high quality PIR insulation board designed with floor applications such as solid concrete and suspended ground floors in mind. It significantly reduces the amount of heat that would otherwise escape through the floor. The energy saved in the process makes for a much more comfortable space, which in turns helps deliver long-term savings both on a financial and environmental level. 

This floor board is a fantastic addition in any solid concrete ground-based floors, but it will also do very well in beam and dense block applications, suspended timber floors, or timber floors on battens. The Kingspan thermafloor board is very versatile and can be applied in any application that requires controlling heat loss.

The Thermafloor TF70 is able to deliver such an amazing thermal performance thanks to its really low U-value standing at just 0.022 W/mK. This means it is even easier to follow and comply with the current building regulations. A highly efficient PIR floor board is what you get when choosing Kingspan Thermafloor TF70. This high performance floor board offers rigid thermoset insulation and responds quickly to temperature changes and prevents heat loss through “heat sumps.” This is a cost-effective floor board as it minimises costs that can be incurred with soil removals, DPM’s, or even service connections.
