First of all, in turnkey house construction there is a selection of samples, often even a preliminary sampling. Admittedly, it is time-consuming, but especially in interior finishing it is worth dealing with the products more intensively. The internet offers a lot of information. The manufacturers provide product information.....

Problem: not every seal found on the market is trustworthy (see various organic labels in the food sector). A product can possibly be contaminated despite a seal. In the past, this was often the case especially in the organic sector.

Regarding the EIFS ... here I would differentiate between ecological aspiration and the desire for the healthiest possible lifestyle. The former is difficult in our civilization, the latter can be done. And in my opinion, what you bring into (!) the house counts primarily.

Yes, you are right there.

However, then one would consistently have to question the materials of the furniture (e.g. couch or mattress), would also have to do without fleece wallpapers and also question curtains and much more.

In the end, personal preferences combined with the available budget decide.

Interesting discussion!

May I ask what you think about OSB boards in this context? These are used in our timber frame construction in the wall structure.

Harmless and ecologically good. However, I cannot assess how the soundproofing looks.

The adhesive in OSB boards naturally also comes from the chemical industry (which I do not view negatively, I am just mentioning it). Formaldehyde emissions are probably no longer an issue, especially if the board is installed covered. So clearly no health concerns and ecologically acceptable.

For proper soundproofing, they are IMHO still too light and too thin. But in timber frame construction, the insulation between the joists takes care of that, right?

Sure, [weichfaserplatten] will be installed there.
