Tile Backer Board 6MM / 10MM 12MM - Floor OR WALL Rigid Hard Insulation UNDERFLOOR Heating Cement 1200MM X 600MM (6MM Pack of 10 Boards)

Strong Enough to Park On - Each square metre of this tile backer board takes the weight of around 30 family cars before it gives: 483 kPa compressive strength (EN 826), 61% above the 300 kPa that EN 13164 requires. A rigid tile underlay that stays solid under heavy floor tiles. Every board is covered by a Declaration of Performance to BS EN 13164. Stays Flat in a Steamy Bathroom - After 2 days at 70 °C and 90% humidity, a 1.2 m backer board moves less than the thickness of a 1p coin: 0.1% size change against a 5% limit (EN 1604). It won't swell or bow, so grout lines stay crack-free in showers, wet rooms, kitchens and over underfloor heating. Cement Board Face That Won't Peel Off - Fibreglass mesh and cement coating on both faces give tile adhesive a firm key. A 10 x 10 cm patch takes about 6 adults pulling to separate it: 465 kPa tensile bond (EN 1607, at least 400 kPa required). Flat to within 1.35 mm per metre (EN 825) for straight, tight tile joints on walls and floors. Waterproof Core, Warm Insulation Board - The XPS foam core keeps heat in the room and tiles warmer underfoot, ideal as an underfloor heating insulation board. The 6 mm board tested at R 0.174 m²K/W (EN 12667); thicker boards insulate more. Soaked for 28 days, the core takes in less than 30 ml of water per litre: WL(T)3 (EN 12087). Seal joints with tanking tape in showers and wet rooms. 1200 x 600 mm, Cuts With a Knife - Each tile backing board covers 0.72 m², lands on 300, 400 or 600 mm stud centres and cuts with a utility knife. Choose 6 or 10 mm for floors, 10 or 12 mm for walls. Washer packs (15 per board) are for timber floors and stud walls; on concrete or masonry use flexible tile adhesive, no washers needed.
