This curved board has grooves cut into one surface that makes it flexible allowing it to be flexed into curves and even circles. Once fixed to a wall or a frame the board provides a strong solid substrate for tiling or plastering. The board can be fixed to a masonry wall using tile adhesive or to a timber or metal frame with suitable support using screws and washers. As with all Marmox Multiboards, they have a blue core of CFC-free extruded polystyrene hard foam which is a thermally insulating waterproof material. As a multiboard, the blue core will absorb lateral movement in the frame or sub-structure which is often the cause of cracked tiles or grout. The board can be used to construct gentle to sharp curves with a radius as small as 200mm.

  • Excellent heat insulation
