Marmox Curved Multiboards are flexible, waterproof XPS construction boards designed to form smooth curved walls, columns, and architectural features. Manufactured with an extruded polystyrene (XPS) core and reinforced cementitious coatings, they allow curved designs to be created without compromising strength, waterproofing, or tile adhesion. Pre-cut slots on one face allow the board to bend to a minimum 200mm radius, providing a tile-ready or render-ready solution for curved interior and exterior applications in both residential and commercial projects.
