THERMOFLOOR underfloor water heating underlay

THERMOFLOOR a new system underlay of a water heated floor made with modern technologies, is an effective heat insulator. The floor water heating pipes can be easily and quickly installed. The new product has even better features, more attractive to installers and users, because:

  • Special raw material is used for products with a harder CS
  • Better sintering of the bean paste granules – therefore a stronger product
  • Increased strength and elasticity – easier installation
  • Due to the density and quality of the raw material, the molded closed-pore product absorbs less moisture.

EVEN DISTRIBUTION OF HEATING PIPES IS GUARANTEED – Your underfloor heating will be all evenly warm, so you and your children will be able to walk, sit and play comfortably on the floor without any fear.


  • 100% comfort at home
  • A +++ heat in your Šilputa home system
  • 100% quality
  • An eco-friendly product.

THERMOFLOOR technical specifcation

THERMOFLOOR heated floor panels – molded foam floors made of special stronger foam brands, which distribute heat more efficiently inside the room and are virtually moisture-proof. The thermal conductivity coefficient is 0.034W/m2k.
With better heat insulation properties, moisture resistance, even installation of tubes distributes heat better inside the room.

THERMOFLOOR is characterized by faster, easier and more efficient installation. There is no need to additionally use many unnecessary materials – film, net, straps, net lifting fasteners. The tube is protected from damage.

Advantages and distinctive features (arguments) that make THERMOFLOOR a special solution for underfloor heating:

  • Easy to lay and install – in virtually all directions, whether simply laying or tying.
  • Each panel has locking joints
  • No need to use film, mesh, tying wire, studs, etc.
  • High laying and installation speed up to 2-4 times
  • Minimum labor costs – 1 worker can workeasily
  • Mounted while standing – no need to kneel, can be mounted with a foot press.
  • Even distribution of pipes vertically and horizontally is guaranteed.
  • Higher work culture – less debris, dirt, less waste.
  • Protection against accidental mechanical damage during installation – no need to cut or cut the net with an angle grinder, no accidental shards into the glass packages, easy to change the direction of the contour, etc.
  • Very siutable to mount a pipe of type PE-RT-AL-PE-RT (with aluminium core)
  • Protection against accidental hidden defects – the floor and pipe can only be installed in the prescribed manner and otherwise no error will be made.

THERMOFLOOR special features

THERMOFLOOR is characterized by special universality. It can be installed directly on polystyrene, on a wooden or monolithic ceiling with or without sound insulation.
The installation is very fast and reliable, we avoid the factor of human error
Due to the presence of molded polystyrene elevations with a cone, the tube is held without additional fixation.
Due to these same elevations, when concreting the floor, you can safely walk across the floor without fearing that the height or reinforcement of the heating pipe will be damaged, as a result of which the contour would be heated inefficiently or unevenly.

  • THERMOFLOOR is a closed cell product of molded foam

  • Innovative edge profiling allows joints to be joined together easily


  • Šildymo vamzdelis tvirtinamas tiesiai į formą
  • Vamzdelių montavimas be papildomų tvirtinimo elementų, ką garantuoja skirtukų forma

  • The chamfered edges in the slabs prevent the concrete from pushing the tubes to the surface
    Molded risers raise the pipe from the bottom of the deck so that the pipe is completely covered with concrete

  • No need to use equivalent foam board, additional netting, straps, studs or thermal insulation pad
  • No additional mesh or thermal insulation mat is required

THERMOFLOOR installation and assembly

  • THERMOFLOOR heated floor panels can be installed on any surface (foam, concrete). The innovative profile of the edges allows for a tight connection of the panels.
  • THERMOFLOOR heated floor panels allow reliable fastening of the heating pipe in all directions without additional fastening. The installation is facilitated by the shape of the bumps on the surface, between which it is convenient to install and properly fix the heating tubes without additional effort. Just insert the tube and you’ll be snug and protected.
  • The unique shape of THERMOFLOOR easily anchors the heating tube, leaving a space below for the concrete/plaster filler. There is no unnecessary air gap and the floor acts as a heating battery, evenly radiating heat to your home.
  • THERMOFLOOR heated floor system can be used without a waterproofing film or a reinforcing mesh.
  • THERMOFLOOR is a reliable way to lay a heated floor and protect yourself even from the factor of human error.
