Key Benefits of ThermRite PRO Boards

Low-Profile Floor Build-Up 16mm and 20mm panel options help keep floor height increases low, making them suitable for retrofits, renovations and height-restricted spaces.
Dual-Purpose Floor Finish Compatibility ThermRite PRO boards can support tile, vinyl, wood and laminate floor finishes when installed in line with the correct floor build-up guidance.
EPS400 High-Strength Core The rigid EPS400 insulation core provides strength, stability and insulation performance for water underfloor heating installations.
200-Micron Aluminium Foil Layer The factory-bonded foil layer helps spread heat across the panel surface and improve upward heat transfer into the room.
No Extra Pipe Fixings Required Pre-formed grooves help retain UFH pipe securely, reducing the need for separate pipe clips or rails.
Trade & Domestic Use Suitable for installers, contractors and homeowners working on low-profile water underfloor heating systems.

ThermRite PRO 16mm vs 20mm Boards

Both ThermRite PRO panels are dual-purpose foil-faced overlay boards for water underfloor heating. The 16mm panel is best where the lowest possible build-up is required and uses 12mm pipe. The 20mm panel offers slightly deeper insulation and is designed for 16mm pipe. Both boards use 150mm pipe centres and are suitable for a range of floor finishes when installed correctly.

Board Pipe Size Best For
ThermRite PRO 16mm 12mm UFH pipe Very low-profile overlay systems, retrofits and rooms with limited floor height.
ThermRite PRO 20mm 16mm UFH pipe Low-profile UFH systems needing larger pipe and slightly deeper insulation.

Best Uses for ThermRite PRO Panels

Retrofit Underfloor Heating ThermRite PRO boards are ideal for adding water UFH over stable existing floors where a low build-up is required.
Renovations & Extensions Use PRO panels for low-profile floor heating in property upgrades, extensions and room refurbishments.
Tile, Vinyl, Wood & Laminate Floors The dual-purpose design supports multiple floor finish options, helping simplify product choice when the final floor covering is not yet confirmed.
Low-Height Floor Build-Ups Choose 16mm or 20mm panels where door thresholds, ceiling heights or existing floor levels limit available build-up.
