He probably meant impact sound insulation… (otherwise I can’t think of anything else…)
yes exactly, I understood it that way too. But with full-surface bonding that would be quite unusual, wouldn’t it? I had only heard that with vinyl and as low build heights as possible.
Yes, it would be, but otherwise I really don't know where three or four millimeters are supposed to come from. Even three millimeters of glue insulate heat, which is not desired.
How much thickness does the adhesive normally add? In other words, what "final height" do I need to specify to the builder?
Assume a total thickness of 18mm. That would be the parquet + thin-bed adhesive (possible leveling compound not included). For every door, there is the option to adjust the height by 2-3mm. Everything mentioned regarding "insulation": please forget that! We are talking about parquet installation here, not impact sound insulation (under screeds)! Regards & good luck: KlaRa

In the meantime, I had also called another specialist shop and a floor installer. They told me 1mm up to a maximum of 1.5mm, as the adhesive is pressed flat. I have now initially passed this on to stair and door builders. There are hundreds of entries on Google for every nonsense. I really don’t understand why nothing can be found about this. The question actually must arise in some construction projects.

You found this forum yourself. Probably via GOOGLE. And you received a professionally sound answer. Not on GOOGLE, but in a specialist forum. From an expert. Once again: the 1mm adhesive thickness you researched does not work in practice. That is too little. On the other hand, you simply cannot "calculate" with 1 or 2mm across the surface. Take the 3mm I specified, then also include the limit values of DIN 18202 regarding flatness deviations in the calculation. The rest is adjusted by the door manufacturer.
