Key Benefits of Solid Floor Tile-On UFH Panels

Tile-Direct Installation Selected panels are designed so tile or stone finishes can be installed directly above the UFH system when fitted to the correct specification.
Low-Profile Floor Build-Up 18mm, 20mm and 25mm board options help keep floor height increases low for renovations, bathrooms and retrofit projects.
Strong XPS & Cementitious Options Choose XPS insulated panels for lightweight strength or ProTile20 cementitious panels for a more robust tiled floor surface.
Pre-Grooved Pipe Channels Routed grooves hold underfloor heating pipe at 150mm centres to support even heat distribution across the floor.
Efficient Heat Transfer Tile and stone finishes transfer heat effectively, making these panels a strong choice for high-output water underfloor heating systems.
Trade & Domestic Use Suitable for installers, contractors and homeowners fitting water underfloor heating over solid floors.

18mm, 25mm and ProTile20 Panels Explained

ThermRite™ solid floor tile-on panels are used to install water underfloor heating over suitable solid floors without the need for a full traditional screed build-up. The 18mm panel is best where the lowest possible build-up is needed, the 25mm panel provides additional insulation and strength for 16mm pipe, and ProTile20 offers a cementitious tile-ready surface for robust tiled installations.

Panel Best For Typical Use
18mm High Output Panel Very low-profile solid floor installations. Bathrooms, kitchens and renovations where floor height is restricted.
25mm Solid Floor Panel Projects requiring more insulation and 16mm pipe compatibility. Tile and stone floors over suitable solid floor substrates.
ProTile20 Tiled UFH floors requiring a durable cementitious overlay panel. Bathrooms, kitchens, high-use tiled areas and robust floor build-ups.

Best Uses for ThermRite™ Solid Floor Tile-On Panels
