Product Code: 10MMTILEBACKER
Tile Backer Boards | Underfloor heating insulation boards
Heat Store 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. Heat Store tile backer 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.
When installing onto concrete sub floor we recommend using our flexible tile adhesive, when installing onto wooden floors we recommend using tile adhesive and screws and washers.
