Different Types of Underfloor Heating Clips and How to Choose

Underfloor heating clips come in many shapes and sizes, and choosing the right type for your installation system is essential. Whether you are using fixing rails, mesh, or insulation boards, there is a clip designed to work with your setup. This guide explains the main types of clips and how to choose between them.

Rail-Mounted Clips

Rail-mounted clips attach to plastic or metal fixing rails that are laid across the subfloor. The clips are either pre-spaced on the rail or attached manually at the required intervals. This system offers excellent control over pipe spacing and is popular in both residential and commercial projects. Rail clips are ideal for large open-plan areas where consistent pipe centers are critical.

Mesh-Compatible Clips

Mesh systems use wire mesh laid over insulation, with clips or staples securing the pipe to the mesh. Mesh clips are designed to grip the mesh wires and hold the pipe at the correct height. This system is flexible and suitable for rooms with complex layouts, but it can be slower to install than rail-based systems.

Insulation Board Clips

Some underfloor heating systems use insulation boards with pre-molded grooves or mushroom clips. In these systems, the pipe simply clicks into the grooves or clips, eliminating the need for separate rails or mesh. This is the fastest installation method and is ideal for projects where speed is a priority.

Choosing the Right Clip Type

• Rail clips: Best for large, open spaces with strict spacing requirements.

• Mesh clips: Flexible and suitable for complex room layouts.

• Board clips: Fastest installation, ideal for time-sensitive projects.

• Pipe diameter: Ensure the clip fits your pipe size, typically 16 mm or 20 mm.

• Material: Choose durable plastic that resists corrosion and will not scratch pipes.

Conclusion

The right clip type depends on your installation system, room layout, and project requirements. By understanding the options available, you can choose the most efficient and reliable fixing method for your underfloor heating project.
