Thermofloors can be used in almost all areas, from new constructions up to complete renovations of old objects. On thermofloors all floor coverings, suitable for
underfloorheating, can be used:

  • Stone coverings
  • Textile coverings
  • Elastic coverings
  • Parquet

At the present time, out of economic and ecological view, rooms are heated and cooled via activated surfaces and the room climate is regulated through pleasant radiant heat. The big advantage shows in the costs, because the larger the heated surface, the less energy has to be used.

Consequently, the costs of heating and cooling are reduced and, in addition, the environment is less burdened and with the help of calcium sulfate plates an optimal heat transport is guaranteed. The pipes for the underfloor heating are set in a special milling in the panel and then closed with putty.

The used pipes are made of highly cross-linked polyethylene, which clearly surpasses the oxygen-tightness of standard requirements. In the substructure pedestals are used, which can be adjusted exactly in height.


  1. The hollow floor with prefabricated millings for the heating medium is built up first, according to the installation plan.
  2. Subsequently the plastic tube is clipped into the holding grooves.
  3. Cutouts can be prefabricated (for example for electric floor tanks).
  4. After the pipes have been tested for leaks, the pipes are embedded with a special filling compound.
  5. After solidification, the supernatant is pushed plane with the surface, thus producing a flat surface of high quality.
  6. After functional heating the cover can be laid.
