Stonefix insulation boards are the perfect insulation product for use with electrical underfloor heating mats. Floors warm up significantly quicker and stay warm longer. Consquently the power required to maintain floor temperature is also significantly reduced. As with all Stoneifx products, the strenght, quality and value of these insulation boardsis unrivalled.
Stonefix insulation boards are manufactured from extruded polystyrene foam. Insulation boards are ideal for use onto concrete sub floors, and are easily strong enough to allow for screeding over the heat mats, as well as tiled floors.
