    Premium Thermal substrate insulation board is a lightweight insulated tile backing board developed specifically for use with tiled floors. It consists of a Polyfoam core with glass fibre reinforced polymer-modified cement faces. It is dimensionally stable, doesn't rot or warp and provides excellent resistance to moisture. It also offers the additional benefit of a high level of thermal insulation, making it the ideal substrate for floor tiling over underfloor heating mat systems. Thermal substrate board is extremely light and easy to cut (using fine tooth saw, jigsaw or utility knife, for example) and to work with.

    Excellent product well priced

    The agent I spoke to recommend an alternative product to the one I had chosen, which turned out to be better suited to the job in hand and was better priced.

    This is fantastic to hear, thank you very much for the great review.
