Fit From Above 400mm Wide Spreader Plate 3 ROWS 150 Pipe Centres

Fit From Above 400mm Wide Spreader Plate – 3 Rows (150mm Centres)

Quick-Install Joist Plate for Even and Efficient Underfloor Heating

Boost the performance of your underfloor heating system with the Hydaheat 400mm Wide Spreader Plate, designed for fit-from-above joist installations. With three precision-formed pipe channels spaced at 150mm centres, this plate ensures consistent heat distribution and fast, stress-free installation.

Deliver Heat Evenly Across the Floor

Thanks to its triple-row design, the plate spreads warmth uniformly across a wide surface area.
As a result, your floors maintain a consistent temperature without hot or cold patches.
Moreover, the 400mm width allows fewer plates to cover more space, which improves installation speed and material efficiency.
In turn, you can achieve better heating results using fewer components.

Install from Above – No Subfloor Access Needed

You can fit this plate directly from the top of the joists—eliminating the need to work underneath.
Therefore, it’s especially useful in retrofit or refurbishment projects where access below is limited.
Furthermore, this top-down installation method simplifies layout adjustments and reduces time spent on site.
Consequently, it improves both workflow and installer comfort.

Built Strong for Long-Term Reliability

Made from durable, corrosion-resistant metal, this spreader plate is designed to last.
Because of its rigid structure, it resists bending under pressure and maintains consistent contact with the pipe.
As a result, the system maintains efficient heat transfer over the lifetime of the installation.
Additionally, the high-quality finish prevents rust and deformation, even in humid environments.

Flexible Pipe Compatibility

The channels suit pipes up to 16mm in diameter, allowing you to use it across a variety of underfloor heating systems.
For instance, it’s perfect for both residential homes and light commercial properties.
In addition, the formed pipe channels hold the pipe firmly in place, making it easier to secure and align during installation.
This helps ensure a consistent 150mm centre layout throughout your project.
