Marmox Multiboards
Waterproof, Tile-Ready Construction Boards
Marmox Multiboards are high-performance, waterproof construction boards designed for walls, floors, ceilings, and wet areas. Manufactured with an extruded polystyrene (XPS) insulation core and fibreglass reinforced polymer-cement coatings on both sides, they provide a durable, tile-ready substrate for modern Australian construction.
Lightweight yet strong, Marmox XPS Multiboards combine waterproofing, thermal insulation, and structural stability in a single board system, making them suitable for both residential and commercial applications.
