Marmox tile backer board / insulation board.
Marmox Tile Backer Boards are ideal for two primary purposes; as a superior waterproof surface to fix wall or floor tiles and as a first class heat insulation for underfloor heating systems. Marmox insulation boards are particularly suited to underfloor and under tile heating applications. Installation below underfloor heating systems on an existing un-insulated concrete or timber sub-floor will greatly reduce heat up time and running costs.
