Marmox Multiboards are high-performance insulated building boards designed to provide a reliable, multi-purpose substrate for a wide range of construction and refurbishment projects. Suitable for use on walls, floors, ceilings, and in wet areas, they combine thermal insulation, moisture resistance, and a stable tiling surface in one product.

Each board features a lightweight extruded polystyrene (XPS) core with a reinforced cement polymer coating on both faces, creating a rigid, durable surface that is ready to tile directly onto. This construction helps to improve thermal performance while also providing a water-resistant barrier, making Multiboards particularly well suited to bathrooms, showers, wetrooms, and other moisture-prone environments.

Marmox Multiboards can be easily cut and shaped on site, allowing for straightforward installation around complex details and irregular spaces. They are compatible with a variety of backgrounds, including masonry, timber frame, and steel frame structures, making them a flexible solution for both new build and renovation projects.

By combining insulation and a tile-ready surface in a single board, Marmox Multiboards help to streamline installation and support efficient, compliant construction across a wide range of applications.

Marmox Multiboards are BBA Approved
