Our XPS Tile Backer Boards provide a strong, waterproof and thermally efficient base for tiling in wet rooms, bathrooms, shower areas and underfloor heating systems. Designed for both DIY and professional installers, these boards offer excellent moisture protection, high compressive strength and quick, easy installation.

Key Features

Waterproof & Moisture Resistant

Made from closed-cell extruded polystyrene (XPS), these backer boards prevent water absorption, mould growth and rot — ideal for high-moisture environments.

Strong Yet Lightweight

The reinforced cementitious coating delivers high strength and durability while keeping the boards lightweight and easy to handle.

Multiple Thickness Options

Choose from 6mm, 10mm, 12.5mm or 20mm depending on your installation needs. Use thinner panels for walls and thicker options for flooring or insulation upgrades.

Improved Thermal Insulation

Perfect for underfloor heating projects, the XPS core maintains heat efficiency and reduces heat loss through subfloors.

Easy to Cut & Install

Score, snap or cut with a utility knife for fast fitting. Suitable for tiles of all sizes and heavy load applications.
