Vario Pro Underfloor Heating & Uncoupling System

Vario Pro

Vario PRO is the fast and easy way to create a warm, comfortable floor that’s protected from tile delamination and cracks.
Vario PRO is the professional combined underfloor heating and uncoupling solution for tiled floors. The fast track installation is quick and easy and creates a floor built to last.

Why do I need an uncoupling layer?

The problem:
All floors, especially new ones, expand and contract with changes in the temperature of the building.
Typically, a floor tile will expand and contract at a different rate to the tile adhesive and sub floor below, resulting in cracked tiles and delamination (tiles coming away from the floor).

The solution:
Introducing a layer of Vario PRO uncoupling membrane helps to prevent cracks and delamination by neutralising the stress between the tiled surface and the sub floor. Vario PRO cannot prevent damage from sheer movement.

  • Underfloor Heating

    Vario ProMat is designed to make it easy to install electric underfloor heating and an uncoupling membrane with one fast track solution.

  • Uncoupling layer

    Vario ProMat neutralises the stress caused by different rates of expansion and contraction in a tiled floor. This minimises the risk of tile delamination and cracking.

  • Superior vapour management

    The studs in the Vario ProMat allow water vapour to escape effectively. This means you can save more time by tiling over a substrate that is not fully cured.

  • Easy waterproofing

    Vario ProMat is totally waterproof, and by using Vario PRO sealing tape on edges and penetrations you can create a wetroom quickly and easily.

  • Efficient load distribution

    Heavy loads are no problem for floors that include a layer of Vario PRO. The stud structure transfers the load to the sub floor eliminating the risk of cracks.

Frequently Asked Questions


What is an uncoupling membrane?

An uncoupling membrane that goes between the tiles and the substrate and reduces the stress between the two layers.

Why do I need an uncoupling layer?

All floor especially new ones expand and contract with the changes in temperature. A typical floor tile will expand and contract at a different rate to the substrate which results in cracked tiles and delamination. The uncoupling layer neutralises the stress between the substrate and the tiles and helps to prevent cracks and delamination.

Is Underfloor Heating safe to be installed in the shower?

Providing that the shower floor is tiled (not a shower base) like the rest of the bathroom floor, all of Thermogroup’s underfloor heating systems are suitable for installation in the shower area.

The cable has an IP (Ingress Protection) rating of IP68 and a continuous earth braid the full length of the cable. This ensures it is safe should the cable come in contact with water and gives you the assurance of safety in the unlikely event of install damage. For further protection we recommend that you do not end the heating system in the shower area.

What is the best Underfloor Heating system for my application?

If you are unsure which floor heating system best suits your needs or daunted by the many options and offerings on the market, Thermogroup's online underfloor heating system selector tool can help you make the best decision. Our underfloor heating selector takes you through a simple four step process to determine the most suitable underfloor heating system for your individual application then also lists out all the products required to get the job done, so you can be assured that you will have everything required when it comes to installation.

What are the rough in or first fix requirements for Underfloor Heating and a Controller?

When roughing in for our Underfloor Heating and the controller, the electrician will first need to bring mains power to the Thermostat location. The electrician will then also need to run two 20mm conduits from the Thermostat position down to the floor, for the Underfloor Heating Cold Tail and for the Floor Sensor. For further information and a visual representation, please view our Conduit Requirements download.
