The ideal solution for reducing your heating costs: SunStone insulation boards prevent heat-loss downwards, this means that the heat produced by your underfloor heating system is retained in the room for longer. Therefore, you use your heating less frequently or for shorter periods of time.

The insulation boards are easy to cut through with a utility knife, which makes shaping the boards to the different forms of your room effortless and ensures perfect insulation across the entirety of the floor.

SunStone Insulation boards can be attached to either concrete or timber subfloors, providing the flexibility you need to increase insulation levels throughout your home. Furthermore, your underfloor heating system can be installed directly on top of the insulation boards without any additional preparatory work required.

Once installed, the Insulation boards can reduce your running costs of your underfloor heating by up to 50%. This is achieved by preventing the heat from escaping downwards. Therefore, the heat is directed in an upward fashion only, meaning that the room remains warm much longer and the heating system requires less time to bring the room to your comfort temperature.

Sunstone boards are also suitable for the boarding of floors and walls prior to tiling, having the ideal 'tile on' surface.
