XPS 500 Underfloor Heating Overlay Boards – Super High Output 120mm

The XPS 500 overlay boards offer a simple solution to install underfloor heating into your home without lifting your floor. The panels can be placed directly onto an existing solid surface and are perfect for retrofit installations. The 20 mm thick boards are low profile and hold 16mm pipe in channels.

These underfloor heating overlay boards have all the features of our standard XPS boards and more. XPS overlay boards have improved durability crafted from high-quality XPS 500. Boards are designed to accommodate 16 mm pipe, with three channels for return pipes. Lightbulb-shaped 180° returns streamline installation while minimising the risk of pipe damage.

UFH overlay boards are topped with 200-micron thick aluminium foil, facilitating swift heat-up times of as low as 30 minutes. Aluminium provides excellent heat distribution, ensuring that heat spreads evenly across the area of the board and the entire floor. The aluminium continues within the pipe channels to improve efficiency. The panels are secured with adhesive and can used with all floor coverings. Most floor coverings can be placed directly on top of our panels, find out more on our datasheet.

These boards are fitted with 120 mm pipe centres and hold 26% more pipe compared to the 150mm XPS Board. This results in a higher heat output which is always desirable.

If the channels and turns are not visible, you can reveal them by walking on the surface. Once the material is laid down, walk over the areas where the turns are located. Applying pressure along the grooves will create visible indents.

Key Features:

• High strength ensures durability and reliability
• Increased heat output for enhanced comfort
• Innovative lightbulb-shaped returns for easy installation
• Versatile compatibility with floor coverings
• Superior heat distribution for maximum efficiency

The installation of low-profile underfloor heating overlay boards is a straightforward process. This involves cutting the boards with a saw and fixing them using glue. Attention to detail during installation is crucial to ensure proper fitting of the system. For comprehensive guidance for low-profile underfloor heating refer to our data sheet below.
