The System

Our Wundatherm system gives you ultimate control, located beneath your floor finish of choice.

With Wundatherm there’s no need to dig up your floors!

Our low profile, over floor systems use close pipe centres, 200 micron aluminium and set back thermostats for Rapid Response ® and optimum control.

Maintaining low input temperatures that make floor heating environmentally friendly and energy ecient. Suitable for both old and new properties.

Heating boards & floor finishes

Choosing the right overfloor heating board is easy with Wundatherm. Knowing the finished floor covering type and required heat up time means you can pick the correct board density and aluminium thickness.

Wundatherm’s the only board that comes factory fitted with 200 micron aluminium – we also offer 3 other thicknesses of aluminium so you can make an informed comparison.

200 Micron Aluminium THICKEST (Best) 30 mins 27°c

100 Micron Aluminium THICKER (Better) 50 mins 24°c

Zero Micron Aluminium THIN (Slow) 120 mins 22°c


We supply pipe in two sizes, one for each solution build up, 20mm boards take our 16mm pipe, 16mm boards take our 12mm pipe


Available in 16mm or 12mm to fit your desired solution, featuring an oxygen barrier for increased lifetime and aluminium core for greater thermal conductivity.

Your Wundatherm Questions

Thanks to retro-fit systems like Wundatherm® 100m2 can be laid in just two days using quick drying Wunda Spray adhesive. It’s no longer a case of digging all your floors up, simply take up your carpet, prepare your sub-floor and lay a retro-fit system. 

Retro-fit options like Wundatherm® are laid directly under your floor finish and when covered with the optimum thickness of 200 micron aluminium they provide Rapid Response® warmth reaching desired temperatures in 30 minutes and ensuring an even heat across the entire floor – this makes floor heating just as controllable as radiators.

Old fashioned floor heating laid deep in concrete could take up to 72 hours to heat up or cool down.

Screed systems are traditionally used in new build projects. Screed systems require the floor heating pipes to be fixed to the subfloor insulation layer prior to being encased in a layer of concrete or chemical screed. The warm water in the pipes heat up the concrete (screed) which acts as a thermal store and radiates it into the living space. This process can take a few hours to both heat up and cool down and is less controllable.
Wundatherm boards are bonded on top of the rooms existing concrete or wooden floors making them ideal for renovations.
Wundatherm is a modular system of lightweight high density eps boards with pre routed channels that secure the floor heating pipe in place. The boards are covered with Aluminium foil that quickly and efficiently spreads the heat from the pipes evenly over the surface of the Wundatherm board. 
The final floor finish is placed directly on top of the Wundatherm board which ensures fast transition of heat from board to living space (rapid response). Because Wundatherm doesn’t rely on a thermal mass to transmit the heat, it warms up and cools down very quickly, about as fast as radiators, this makes Wundatherm systems very controllable.

No! That’s the old fashioned way. Modern floor heating such as Wundatherm® comes in moulded, easy to shape, high density polystyrene aluminium coated boards made from eco-friendly EPS (as opposed to harmful XPS). The board is bonded to the existing floor before running the pipes in and through to the manifold. The desired floor finish is laid on top – no digging, no mess!
