Drywall on underfloor heating


Increasingly, residential properties are equipped with underfloor heating. If a drywall is to be retrofitted, the question quickly arises as to how the floor profiles should be fastened.

Floor heating and drywall - how to fasten?

The trend towards underfloor heating is obvious. More and more residential properties are equipped with underfloor heating. But over the years, the residents change or the circumstances change, so a division of space is to take place. Of course, the preferred material is the drywall, because quickly and inexpensively positioned.

The most important challenges

In this situation, there are several problems:

  • Fixing the floor profiles to the floor
  • Fixing the floor profiles on the screed or floor covering

Fixing floor profiles on unfinished floor or screed or floor covering

The attachment of the floor profiles is problematic, since there is a floor heating. The risk of drilling a floor heating heating tube when drilling the mounting holes is quite high.

In addition, it should be added that a drywall should not be attached to screed or any other flooring, if one follows the technical building standards.

The soundproofing can hardly be produced at all. This aspect must be taken into account in any case; especially if it is to be a long-term construction. You have to weigh the pros and cons carefully.

Fixing on screed with underfloor heating

Conventionally, the floor profiles are screwed into the floor. However, there is the risk that the heating coil of the underfloor heating could be drilled. The resulting follow-up costs are certainly high. Although the screed above the underfloor heating should have a thickness of at least 4.5 cm, the question is whether you can really rely on it.

Attach floor profile with nailer

Otherwise, you still have the option to attach the bottom profile with a nailer, which depending on the device has a depth of insertion between 2.0 and 3.0 cm. Whether you can do this depends on the requirements of the drywall. If it is a pure dividing wall without later significant load, this alternative is sufficient.

Glue soil profile

If the subsequent load on the drywall is certain to be very low in the long term, you can also glue the soil profile if necessary. In particular, if the stand can be attached to the left and right sides of walls, this possibility of attachment is sufficient. Especially on a substrate such as laminate, this can mean at least a little noise protection.
