Overlay Underfloor Heating – Warmth Without Major Renovations
Perfect for retrofits and renovations, our overlay panels allow underfloor heating to be fitted with minimal floor height build-up and no messy excavation.
What is an overlay system?
Overlay systems are slim boards that sit directly on top of your existing floor. Pipes are laid into pre-routed channels within the panels, then your chosen floor finish goes on top. With build-ups as low as 18mm, overlay is ideal when you can’t mill into concrete or don’t want the disruption of digging out floors.
When to use overlay:
Timber floors or surfaces not suitable for milling
Where minimal floor height build-up is required
Renovations where speed and low disruption are key
Upstairs floors / bathrooms
Properties where concrete milling is not an option
How Installation Works
Step one: Preparation
Floors are checked for level and cleaned.
Step two: Panel Laying
Slim overlay boards are fixed directly on top of your existing floor.
Step three: Pipe Installation
Heating pipes are pressed into the pre-cut channels.
Step four: Connections
Pipes connect back to a manifold and your heating system.
Step five: Floor Finishes
Tiles, engineered wood, carpet, or vinyl can be laid over the boards.
Step six: Commissioning
The system is pressure-tested and thermostats are installed.
