Marmox Tile Backer Boards for Wetrooms and Floors

The closed-cell extruded polystyrene core ensures water cannot pass through the board, creating an ideal moisture barrier for showers, steam rooms, and wetrooms.

Marmox boards reflect heat upward into the room, significantly reducing warming times and energy loss when paired with underfloor heating systems.

Laying Marmox over timber subfloors absorbs lateral movement, protecting grout lines and preventing tile stress cracks over time.

Manufactured with a fibreglass mesh and polymer cement coating, these lightweight boards easily support heavy ceramic, porcelain, and natural stone wall tiles up to sixty kilograms per square metre.
