Rayotec Cable Mat System With WEB-TECH Technology

Rayotec are introducing the new to UK market, German designed, double conductor cable heating mat. The mat is made up of a shielded twin core cable that is fixed onto a unique fibre web mesh.

The advantages of this system include:

No sticky primer required for tiled floors

The WEB-TECH Adhesive Technology of the mesh means that in most cases a primer will not be required under tiled floor. The heating mesh simply holds itself to the insulation with a small amount of duck tape (150W/m2 only). Ultra thin

The heating cable is a mere 4mm, so you can tile directly on top of it with a thin layer of flexible tile adhesive.

Primary Heating

Great things come in small packages, this thin cable has a powerful output of approximately 150W/m2- enough to provide primary heating in most rooms that are up to building regulations.

Fixed Spacing

The cables are fixed on to the mesh at fixed spacing's, so there is no need for constant adjustment and time consuming laying.

Approval Details

The compliance with all necessary requirements is approved by appropriate certificates:

Minimal wiring

One mat can cover up to 14m2, which means in most rooms there will be only one or two mats that will need to be wired into your home.

16 year Manufacturers Warranty

The Manufacturers of this fantastic cable mat system have installed underfloor heating systems in excess of 2,500,000 worldwide.

* Primer may be required if floor is not completely clean and free of loose debris.

Why vinyl floorings are ideal to install above electric underfloor heating mats:

  • LogoBecause the Karndean, Amtico and vinyl are all very thin (about 7mm) that allow the heat from the electric heating mats to pass through easily. This gives the system a fast warm up time and high output making it an ideal floor covering.
  • The fact that floor covering is thin also means that when retrofitting the floor build up is minimal. This can prevent problems with door heights skirting boards or allows you to add more insulation.

Things to look out for:

  • Maximum temperature – Karndean, Amtico and vinyl should not be heated to over 27C. It is important to have a floor sensor provided as part of the thermostat to make sure that the underfloor heating never damages the flooring.
  • Special Adhesive – The manufacturers often specify that the floor covering be stuck down using a high temperature version of their adhesive. The high temperature version normally have a model number beginning with HT to denote its ability to withstand higher temperatures.
  • Level floors – It is important that all the floor covering as fixed onto completely flat and stable subfloor floors. We would always recommend the use of flexible tile adhesive above the heating mats. If installing on a suspended wooden floor the 6mm ply needs to fixed to the floor boards similar to good practice to when you tile.

General installation guide

  1. Self Levelling CompoundPreparing subfloor: Make sure that the subfloor is level and clean. If you are installing on a suspended floor with traditional floor boards then a 6mm layer of marine grade plywood will need fixed on top before laying the insulation.
  2. Insulation: The type of insulation differs depending on the exact flooring, traffic over the area and subfloor construction. Please contact us (01932 784848) for details specific for your property. The insulation is stuck down with a flexible tile adhesive applied using a trowel.
  3. Test mat
  4. Fixing the mats down: The mats have to be fixed down very securely otherwise they will float up when the self levelling compound is poured ontop. To ensure this happens the floor has to be kept completely clean so that the adhesive of the mat has maximum contact with the insulation
  5. Test mats
  6. The self levelling compound: Always use a flexible self levelling compound of at least 8mm thick
  7.  Fixing the flooring ontop: Follow the flooring manufacturers guideline for laying the flooring. Many of them have their own high temperature adhesives which they recommend you using.
  8. Turning the system on: The underfloor heating must be switched off 48 hours before, during, and 48 hours after the installation, then temperature gradually increased (typically 3°C/hr) to desired warmth.

This only a guideline. Always read and follow the instructions of the self levelling compound and flooring manufacturer.

How to save money and use less self-levelling compound 

If you are having an Amtico ,Karden or any kind of stuck down flooring then you will have to cover the heating mat with a flexible self-levelling compound. It is vitally important to make sure that the electric underfloor heating mat is as flat as possible to reduce the amount of self-levelling compound you need to use.

The floor must be very clean before laying the mats and use underfloor heating cloth tape to tape down the edges for the flattest possible finish. 

The thickness of the self-levelling used differs depending on the brand but should be at least 3mm from the top of the heating element.
