Waterproof XPS Tile Backer Board with Washers Pack of 5

These XPS tile backer boards are designed to create a reliable, waterproof base for wall and floor tiling in wet and humid areas. Ideal for bathrooms, wet rooms, showers and kitchens, they provide a stable surface that helps support a long-lasting tiled finish while also adding thermal insulation.

Each board features a closed-cell XPS foam core with a reinforced coating on both sides. The surface is faced with fibreglass mesh and a polymer-cement layer, giving you a durable tiling substrate that is easy to handle, cut and fit. The waterproof foam core also offers resistance to water vapour, making these boards a practical choice for moisture-prone spaces.

This pack is suitable for both professional installers and DIY projects. The boards can be used on walls and floors, including over underfloor heating systems where insulation beneath tiles is beneficial. Their lightweight construction makes transport and installation easier, while the rigid structure helps create a sound base before tiling.

Also included are fixing washers for secure mechanical fixing of the boards. Their perforated design helps adhesives and plasters bond through the washer, while the countersunk shape allows the fixing to sit neatly without standing proud of the board surface. Suitable for renovation work and new builds alike, this pack offers a convenient solution for preparing moisture-exposed areas for tiling.
