Grooved Overlay Panels

Grooved Overlay Panels provide a high‑performance, low‑profile solution for installing wet underfloor heating systems in both new builds and renovation projects. These precision‑engineered panels are manufactured from highly conductive materials—typically aluminium‑faced boards or advanced composite substrates—to deliver rapid, even heat distribution across the entire floor area.

Each panel is pre‑routed with accurately spaced grooves that form channels for underfloor heating pipework. The pipe sits securely within these grooves, ensuring excellent contact with the conductive surface and maximising heat transfer. Because the panels are installed directly over the existing subfloor, they create a slim, efficient heating layer without the need for excavation, screeding, or major structural alterations.

The system operates by circulating warm water through the pipe channels. Heat is transferred through the panel and radiates upward through the floor finish, creating a comfortable, evenly heated living space. Controlled via a thermostat, the system maintains consistent temperatures while operating at low water temperatures, making it highly energy‑efficient and compatible with modern heat pumps and condensing boilers.

One of the key advantages of grooved overlay panels is their versatility and minimal disruption during installation. They are ideal for retrofit projects where floor height and installation time are critical considerations. Their lightweight construction and modular format allow installers to work quickly and cleanly, reducing downtime and avoiding the mess associated with traditional screeded systems.
