22mm XPS Underfloor Heating Overlay Board
Our 22mm XPS Underfloor Heating Overlay Board provides a fast and effective solution for installing water underfloor heating without the need for traditional screed. Manufactured from high-density extruded polystyrene (XPS), these lightweight insulated boards offer excellent thermal performance while keeping floor build-up to an absolute minimum.
Featuring a 4-channel routed design, the boards securely hold underfloor heating pipe in place, making installation quick and straightforward. Suitable for refurbishment projects, extensions and new-build properties, they deliver excellent heat distribution while reducing installation time.
Whether you’re a professional installer or a homeowner completing a renovation, these overlay boards provide a practical and reliable foundation for a modern water underfloor heating system.
Why Choose Our 22mm XPS Overlay Boards?
Low-profile systems continue to grow in popularity because they offer excellent heating performance without significantly increasing floor height.
Perfect for Retrofit Projects
At just 22mm thick, these boards minimise floor build-up, making them ideal for renovation work where floor levels are critical.
Excellent Thermal Insulation
High-density XPS provides outstanding insulation, directing heat upwards into the room instead of allowing it to escape into the subfloor.
Fast Installation
The precision-routed channels make pipe installation quick and help keep the pipe securely positioned during fitting.
Lightweight and Easy to Cut
The boards are easy to transport, trim and install using standard tools, helping reduce labour time on site.
