Underfloor Heating Boards Cement XPS 16mm

These XPS underfloor heating insulation boards are designed to improve the performance of water-based underfloor heating systems. The grooved surface securely guides 16mm pipe into place, helping create a consistent layout while reducing heat loss into the subfloor. By improving heat direction and distribution, the boards support a warmer and more energy-efficient finished floor.

Made from extruded polystyrene with a cement-coated surface, the boards combine thermal insulation with strength and moisture resistance. Their lightweight construction makes them easier to handle, carry and position during installation, while the grooved pattern helps keep pipe runs neat and evenly spaced. The cement-coated finish also provides a practical surface layer for use within suitable floor build-ups.

The boards are suitable for a wide range of domestic renovation and new-build projects where water underfloor heating is being installed. They can be used beneath common floor finishes such as tiles, laminate and engineered wood, making them a versatile choice for kitchens, living spaces, bathrooms and other interior rooms.

Each board is produced in a fixed panel size and is intended for 16mm underfloor heating pipe with 150mm channel spacing. Multiple pack size options are available, allowing you to choose the quantity needed for smaller rooms or larger installation areas, so planning coverage is easier whether you are fitting a single room or a wider floor area.
