Marmox Multiboard is ideal for many applications. In addition to being a lightweight tile backer board, it is used for waterproofing, dry-lining and to provide thermal insulation. As a tile backer board, they provide an effective decoupling layer to prevent tiles and grout from cracking due to horizontal movement in the floor.
The unique patented surface of Marmox Multiboards allows tiles of a much heavier weight to be safely and securely fixed to walls. Being completely impermeable to water, they are doubly useful in tiled areas prone to moisture such as kitchens and bathrooms where they will act as a moisture barrier protecting the walls and floor. Multiboards can be used to insulate and waterproof walls, floors and ceilings and noticeable benefits will be gained by using any thicknesses of 10mm and above. The thinner 4mm and 6mm boards are mainly designed as waterproof tile backer boards but these will also provide some thermal insulation and even the thinnest boards will be useful when used with underfloor heating wire to reduce your heating costs.
Please note that one board is equivalent to 0.75m2
