⚡ At a Glance
- • Cutting Quality: Hand-trimmable with a sharp stanley knife and straight edge for neat on-site shaping
- • Best for: DIYers and tradespeople tiling bathrooms, kitchens and ensuites, especially with underfloor heating
- • Not ideal for: Structural load-bearing uses or external applications exposed to direct weather
XPS foam core bonded to a fibre cement face in 600 x 1200mm boards. Available in 6mm, 10mm and 12mm thicknesses with a ±1mm tolerance.
Warmer floors and better energy efficiency – with insulated XPS foam core
An XPS foam core provides thermal resistance that helps retain heat from underfloor heating systems; U value as low as W/m2 on 12mm tile boards is stated by the manufacturer. The insulation layer is bonded between rigid faces to form a composite board that limits heat loss through the subfloor.
Tiles remain warmer underfoot and underfloor heating runs more efficiently, reducing wasted energy and improving comfort.
Fast, low-tool installation – with boards cuttable by a stanley knife
Boards are designed to be trimmed using a sharp stanley knife and straight edge, avoiding the need for power tools for most cuts. Fixings are applied by drilling through and using wood screws with 36mm steel washers, with a recommended 15 fixings per board.
Saves time and keeps mess to a minimum, making the boards practical for small bathrooms and tight access areas.
Reliable tile adhesion and less grout cracking – with a fibre cement board face
A rigid fibre cement facing on both sides provides a stable substrate that accepts tile adhesives more readily than timber or plasterboard. Reduced flex under load helps prevent grout cracking, with a quoted maximum tile loading weight of 62kg/m2 (CERAM121107).
Creates a durable, stable tiling surface suitable for large format tiles and heavy finishes, reducing the risk of movement-related failures.
