Marmox Multiboard is ideal for many UK applications. In addition to being a lightweight tile backer board option, it is used for waterproofing, dry-lining and to provide thermal insulation.
As a tile and shower backer board, it provides an effective decoupling membrane to prevent tiles and grout from cracking due to horizontal movement in the floor. The unique patented surface of Marmox Multiboard allows heavier tiles to be safely and securely fixed to walls. Being completely impermeable to water, it is doubly useful in areas prone to moisture, making it a good option for anyone looking for a kitchen or bathroom tile board.
Multiboard 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 6mm boards are mainly designed as waterproof tile backer board options, but these will also provide some thermal insulation. Even the thinnest boards will be useful when used with underfloor heating wire to reduce your heating costs.
Marmox Multiboard is not just suitable as a tile backer board or insulation board beneath plaster within a building. Because Marmox Multiboard is certified for external use, it can be used as an external tile backer board and can also be used outside beneath a coating of render.
Why choose Marmox Multiboard underfloor heating insulation?
Marmox Multiboard is a fully waterproof insulation board with excellent load-bearing strength of 40 tonnes per square metre and is very easy to handle when installing. Marmox Multiboard is unaffected by the freeze/thaw cycle, and being CFC-, HCFC- and asbestos-free, it is safe for use in any location.
Compared to plain polystyrene (which is unsuitable for underfloor heating) Marmox Multiboard outperforms on all levels with its insulation products.
As well as underfloor heating insulation, Marmox Multiboard can also be used on walls and ceilings as a waterproofing and insulating surface. It is especially useful in locations where damp can be a problem like wet rooms.
