Which type of flooring on underfloor heating

Hello everyone, we intend to lay tiles and parquet flooring in our future house or have it laid. Tiles are to be installed throughout the entire ground floor except for the study, and on the upper floor in the bathroom and hallway. The other rooms will have wooden floors, which I want to do myself. We were thinking of engineered parquet and originally I assumed that it had to be firmly glued down. Recently, a tennis friend told me that this is no longer necessarily required. And he understands something about construction. Floating installation is also possible, provided that suitable impact sound insulation is used. It was also installed that way in his daughter's home and it would not impair the function of the underfloor heating. This was also confirmed to me by several parquet dealers. The only disadvantage is that transition strips have to be used. There are also opinions that say that the floor must definitely be glued down. Impact sound is only of minor importance to us. Nobody wears street shoes in our house anyway, at least not in the bedrooms and guest rooms. Also, the possibility of sanding later is not a criterion. Meanwhile, I also read that someone used 15 mm thick solid wood planks. Of course, these were glued down. Does anyone have experience with this?

Hello,

Engineered wood flooring (i.e. 3-layer construction: wear layer / core layer / back layer) can be installed floating like laminate. In most cases, engineered wood flooring also has a "similar" click connection like laminate and is thus easy for private individuals to install.

A suitable impact sound insulation for underfloor heating should be used. In addition to walking and impact sound, also pay attention to transmission values for heat.

Alternatively, the engineered wood flooring can also be fully glued down. This should preferably be done by a professional, as it involves a greater amount of work.

Solid wood planks (a whole piece of wood) expand and contract significantly. Here, full-surface gluing is definitely recommended.

Attention: Electrical underfloor heating systems are not approved by some parquet suppliers. If present, please obtain approval from the supplier again.

If you have any further questions, feel free to contact us.

Thank you very much. That also corresponds to what I have heard from others. Since I have already installed both (floating) parquet and tiles, I would definitely feel confident about gluing it down. However, the floating installation is more comfortable for me. I might not do that in the living room, but in the other rooms there won’t be that much walking around. There are two of us, and when the children visit, I don’t mind if it is possibly a bit louder.

we glued the parquet ourselves and also laid some floating. The glued parquet feels much more high-quality, you cannot compare it with the floating one. I also don't find floating laid parquet much better than laminate. Installing glued parquet can definitely be done by yourself with the appropriate information.

Best regards
Sabine

Does anyone actually have any idea if there is a guideline for how long you have to wait until the screed is dry enough to cover it with parquet? However, I am aware that this depends on several factors and that the residual moisture should be measured before covering.

A guideline value is difficult; it depends on many factors, including the screed and heating system. It is very important to keep a protocol.
