ThermRite™ Floating Floor UFH Panel – 18mm Foil-Faced EPS Board with 150mm Pipe Centres for 12mm Pipe

ThermRite™ Floating Floor System is the ideal low-depth underfloor heating solution for installations over existing screed or floorboards—perfect for both domestic and commercial applications. With a panel thickness of just 18mm and designed for 150mm pipe centres, it's an excellent choice for projects with higher heat loss (e.g. poorly insulated rooms, glazed extensions, or heat pump-fed systems).

Each 1200 x 600 x 18mm foil-faced EPS panel features 4 pre-grooved channels to securely hold 12mm Pex-Al-Pex pipes without additional fixings. The radiused groove design, paired with a high-performance foil layer, ensures rapid heat-up times and even heat distribution across the entire floor surface.

🏠 Perfect for Renovations:

Lay directly over existing concrete, screed, or timber floors—no wet trades or drying time required. Simply install the pipes into the grooves and finish with interlocking chipboard or plywood for a floating floor build-up.

❓Frequently Asked Questions (FAQs):

Q1: What pipe size does the ThermRite™ panel support?

A: It is designed to hold 12mm Pex-Al-Pex pipe securely in the pre-grooved channels without additional clips.

Q2: Is this panel suitable for existing floors?

A: Yes, it’s designed to be laid directly over existing screed or timber floors, making it ideal for retrofit projects where minimal height build-up is essential.

Q3: What type of flooring can be laid on top?

A: Use 18mm minimum tongued & grooved chipboard or wood/laminate interlocking strip flooring for domestic applications.

Q4: Why are the pipe centres set at 150mm?

A: 150mm centres are ideal for higher heat demand areas or low-temperature systems such as heat pumps, ensuring efficient heating performance.

Q5: What makes the foil surface effective?

A: The bonded foil layer enhances radiant heat transfer and significantly reduces warm-up time compared to traditional screed systems.
