22mm Plain Underfloor Heating Board – Pre-Routed Chipboard – 600mm Wide

ResoThermchip® Grooved Chipboard Underfloor Heating Panels

ResoThermchip® is a high-performance underfloor heating panel designed for timber joisted floors in both new-build and retrofit applications. Manufactured from FSC® certified P5 moisture-resistant chipboard, the boards are precision-routed to accommodate 12mm or 16mm UFH pipework, providing excellent heat transfer and even heat distribution throughout the floor.

The true TG4 tongue-and-groove profile allows for fast, secure installation directly onto floor joists using standard chipboard screws and joint adhesive. Once the pipework is installed, a 6mm fibre cement cover board is bonded and screwed over the panels to restore structural strength and provide a stable base for floor finishes.

Suitable for laminate, engineered wood, hardwood, carpet and LVT flooring. For LVT installations, a 3-4mm levelling compound is recommended over the cement board to create a smooth finish.
