12mm Tile Backer Board Pack of 125 with 750 Steel Washer Discs and 5m Waterproof Membrane Tape (Set of 125)

Prepare larger wall and floor tiling areas with this pack of 125 12mm insulated tile backer boards. Each board measures 1200mm x 600mm and covers approximately 0.72m², giving a total board coverage of approximately 90.00m² before cuts and wastage. The boards feature an XPS foam core with a rigid cementitious and fibreglass mesh coating to provide a lightweight, insulated, tile-ready surface for bathrooms, kitchens, ensuites, wet rooms, and underfloor heating applications. The 12mm thickness is recommended for wall tiling and suitable for heavy-duty tiled areas where a stronger backing board is preferred. The included 750 steel washer discs support mechanical fixing, while the 5m waterproof membrane tape helps seal joints and wet-area transitions.
