What makes our Rayoflex foil mats so special
The system has an output of 150W/m² which is amongst the highest available for use under wooden floors. This gives a faster warm up time and is sufficient to provide the sole source of heat in most rooms.
The mat is less than 2mm thick so that you lose little height in retrofits.
Superior Build Quality
The heating cable is stitched to the foil instead of being taped or glued. This unique feature makes the mat much more robust and flexible so it lays flatter and is easier to manipulate during installation.
As with all of our mats it is earthed for added safety.

Engineered Wood flooring
What it is: It is a top layer of real wood stuck onto plywood. Typically between 14-18mm in thickness
What are the advantages: Looks like solid flooring, Can often be sanded and revarnished, Hard wearing, Heat resistant and not prone to warping. Often installed as a floating floor.

9 Key points to safely using electric underfloor heating under wood floors
(1) Moisture content
This is mainly an issue with solid wooden floors but it is important that the moisture content of the floor is kept at 8% or less to avoid warping. Check with the manufacturers upon ordering and make sure that the wood in transported and stored in a dry environment
(2) Thickness of wood flooring
Wood in not a great conductor of heat so the thinner it is the higher the output of the system and the faster the warm up time. The maximum recommended thickness is 18mm.
(3) Floating floor
Obviously you can’t nail a wooden floor down if you an electric underfloor heating mat underneath. All floors must be floating. It is possible to stick down wooden floors but you need a different mat. Call the office for more details.
(4) Wooden floor underlay
It is possible to use a specialist wooden floor underlay over the electric underfloor heating mat but make sure it’s thin and is not the foil reflective type.
(5) Maximum floor temperature
Wooden floors should never get above 27C. The room thermostats should have a floor probes which will automatically shut of the underfloor heating if the floors get above this temperature. All of Rayotec’s thermostats have floor probes to protect the flooring.
(6) Let your flooring acclimatise
After you have installed the wooden flooring do not turn on the underfloor heating until the flooring has acclimatised. The length of time depends on the thickness of wood but it is typically 7-14 days.
(7) Expansion gap
An expansion gap should always be left around the flooring. This is typically between 10-30mm (ask your flooring supplier for more details).
(8) Earthed system
Make sure that the underfloor heating protect you sell is earthed for safety reasons even if it not installed in a wet room. All of Rayotec’s electric underfloor heating mats are earthed.
Always use a suitable insulation under the electric underfloor heating. Not only does it reduce warm up time and running costs but it also protect the matting. Rayotec supply the advanced Palziv system that not only protects your underfloor heating mats but has fantastic insulation properties and a foot fall sound dampening effect.
