Many of our products for fixing tiles and waterproofing also have fantastic insulation properties too. Tile backer boards and decoupling membranes reduce heat loss and are commonly used to make electric underfloor heating systems more thermally efficient, whilst providing a waterproof decoupling layer to tile directly onto! Meanwhile Marmox Thermoblock load bearing insulation blocks can be used during build and renovation work to keep heat locked in your wall and floor junctions.
