Solid wood parquet on underfloor heating

So there is flexible adhesive for that, so you can also work with bonding that bridges cracks. But the causal chain does not seem conclusive to me here either.

However, he now wants to glue the parquet. I find that so-so. Apparently to decouple the flooring from the substrate because of the cracks. Is that necessary?

and sorry, it was probably too late yesterday and I was mistaken. You are of course completely right. I actually wanted to say that originally gluing was planned and "for decoupling from the critical substrate/cracks" now the floating installation... that’s what surprises me a bit, because although the screed has a crack running through the room, it has been there for quite some time. What he meant was that if you stop the crack, the screed could instead crack elsewhere. I just can’t judge that. My expert only said that he thinks nothing should happen after this time. Basically, the floating installation would be a good alternative. What I read, however, is that sanding is more difficult and in general the durability of the floor is shorter because the stress is greater due to the floating installation.

Ah, I see. Yes, that makes more sense. So as you can tell, there are many opinions here. I don't think you can really say right or wrong. I think a floor like that is only sanded down when moving out or if it's completely renovated. And then you can have it done -> the craftsman's problem. Regarding durability: I think if you really use solid wood planks, and don't regularly pour noodle water on the floor or hang laundry to dry on it, you'll probably outlive the floor—no matter how it's installed.

As far as I understand you correctly, you tend a bit more towards floating installation. Through lots of reading and informing yourself, which is in itself something positive, you are now uncertain. Which floor do you want to install? Solid wood planks or engineered parquet? As already explained several times, you cannot do anything wrong as long as the chosen installation method is carried out correctly. The problem often is that one wants to put all advantages into one decision (at least I do), but that’s not possible. Then there are also showpiece arguments regarding sanding, wear, etc., which are often used as killer arguments. As a "normal" user, nothing will happen anyway! If you want to flood rooms permanently or drive herds of elephants through them, you might reconsider. My tip: don’t let yourself be driven crazy and find someone who implements the installation method you prefer, then it will be fine! I really don’t know how a floating floor should fail under its load. If you look long enough on the Internet for what it means when your left toe tickles, you better start looking for a reliable funeral home. :eek: Everything has already been mentioned here, so you can decide completely safely and freely, you just have to weigh the advantages and disadvantages of each installation method. One is bothered by possible sanding, another by the toxic glue, the next by the hard or soft feeling when walking... I’m curious what number you will roll :D But don’t worry, I absolutely understand your back and forth, I have the same with almost every decision. The really important things, though, I have always decided in no time.....o_O

thank you....no, those are not solid wood planks. This is (multi-layer?) parquet (13.5 mm) with a wear layer of 3.5 mm...at least that's what the offer says...however, I read something about a 2.5 mm wear layer from the manufacturer. These are definitely country house planks.

You also don't walk on 2.5mm, most other coverings often have a thinner wear layer. This is probably a "normal" prefinished parquet that you can glue down or lay floating.
