Collection: ThermRite™ Solid Floor Tile on Panel

Everything You Need to Know About Our Tile Direct Panels

18mm ThermRite HIGH OUTPUT Low Profile Floor Panel

The 18mm High Output Low Profile panel is a slim, XPS-based underfloor-heating board with pre-grooved channels for pipes at 150mm centres — designed for direct tile installation over existing floors. It’s ideal when minimal floor build-up is required and you want efficient, even heating under tiles in bathrooms, kitchens or other tiled areas.

ThermRite 25mm Solid Floor UFH Panel

This 25mm panel uses high-strength XPS foam (300 kPa compressive strength) with pre-grooved tracks for 16mm underfloor-heating pipe at 150mm centres, ideal for tile and stone floor finishes. It offers robust insulation, stability and structural support — suited to both domestic and commercial applications, and performs especially well in rooms with heavy foot traffic or heavier tile/stone finishes.

ProTile20 Cementitious Insulation Panel

The ProTile20 is a 20mm cementitious overlay panel for underfloor heating systems — combining a strong XPS core with a cementitious top layer for superior heat conduction and high load-bearing capacity. It’s designed for tile or stone floors laid directly on top (no screed needed), making it a great choice when you want a lower-profile system with efficient thermal performance and a durable, hard-wearing finish.

ThermRite PRO Adhesive 500ml

ThermRite PRO Adhesive gives a reliable bond for Solid Floor and Tile-On-Panel installations — essential when installing panels over screed or suitable plywood decks before tiling or levelling. It ensures panels remain fixed and stable, helping prevent movement or shifting underfoot — a key step for a secure, lasting finish.

Why ThermRite Solid Floor Panels are Ideal for Tile-On-Panel Installations

Low profile build-up — Boards from 18mm up ensure minimal floor height increase, useful in renovations or where door-clearances and ceiling heights matter.

Strong insulation + high compressive strength — Panels use XPS or cementitious materials designed for tile/stone floors, offering stability under heavy loads and efficient heat retention.

Pre-grooved for UFH pipes — Grooves at standard 150 mm spacing for 12mm or 16mm pipes speed up installation and ensure even heat distribution.

Direct tile application — Many panels accept tiles or stone finishes directly (after pipe installation), removing necessity for bulky screeds — saving time and reducing floor buildup.

Suitable for a range of project types — Whether domestic bathrooms, kitchens, or commercial spaces with tile or stone floors, the Solid Floor system adapts to varying load, insulation, and space requirements.
