I didn't consider the moisture. So when I read it like this, it's quite a huge effort; I thought it would be simpler. How much height can you actually gain with my current floor structure of 18cm?
What height can you actually gain with my current floor construction of 18cm?
Minimum build-up height with very good insulation at about 73-75mm (yes, with underfloor heating) without flooring. So you can save 10cm if you push everything to the limit. I really mean everything that is technically feasible. 20mm vacuum insulation panels (equivalent to about 100mm EPS WLG 035), studded panel for underfloor heating, cast asphalt screed. As soon as you deviate from this, it gets thicker and you save less. Then it costs somewhere over €200 per sqm without underfloor heating...
Wow, I wouldn't have thought you could lower it that much, so there's easily 5cm possible, with a normal setup, right? If I actually do this, then better insulation needs to be installed. I currently have something around 2.46 - 2.47 ceiling height.

Then your idea is complete nonsense. No, wrong. Not nonsense, but an insanely costly gimmick, since you have a perfectly normal ceiling height. At 220 cm or less, one could consider it.
But spending a mid five-figure € amount at that height? Nonsense.
Thank you for your opinions, now I am a bit wiser. How much can the screed be ground down if I only replace the floor covering with a thicker one that has better impact sound insulation?
