Underfloor Heating Plastic Castellated Floor Panel for 15mm and 16mm Pipe
Description
The Plastic Castellated Floor Panel is a low profile, fast-fit pipe retaining system designed for easy and accurate installation of 15mm and 16mm underfloor heating pipes. The castellated design securely grips the pipe without the need for additional clips, allowing quick piping installation ready for screeding.
These injection-moulded durable plastic panels interlock to form a continuous underfloor grid that supports and spaces pipes precisely at selectable centres (50mm, 100mm, 150mm, or 200mm). Their low 20mm height minimizes floor build-up, making them ideal for renovations and new builds where floor height is limited.
What’s Included
- Panels sized 1220mm x 820mm x 20mm (each panel covers 1.0m²)
- Designed for 15mm & 16mm underfloor heating pipe diameters
- Installation instructions included
Key Features
- Low profile panel thickness: 20mm total height
- Accurately spaced castellated knobs for pipe retention at multiples of 50mm pipe centres (50, 100, 150, 200mm)
- Interlocking edges allow seamless panel alignment and continuous coverage
- Compatible with 15mm and 16mm multilayer underfloor heating pipes
- Strong, durable injection-moulded plastic for longevity and repeated screeding resistance
- Eliminates need for separate pipe clips, speeding installation

- Panels overlap for full coverage without gaps, removing need for additional damp proof membranes (DPM)
