Prefabricated house, poor sound insulation

And when the wolf comes, he blows the wooden house down.

*Irony off

Hello Lenschke

that was not bashing against all prefabricated houses. Certainly not against solid wood houses. A good friend of mine builds these houses. Great. But not for me.
I am only saying something against those cheaply cobbled-together prefabricated houses, through whose walls you can get in with a mason's hammer in 5 minutes. The saying "buy cheap, buy twice" is appropriate here. But to then buy a "reasonable house," there is usually no money left.

That has nothing to do with having money or not. Well, if it were cheap, but it isn’t! I agree with you, for me a house should be built with masonry inside and out. But everyone should do as they please. I haven’t given it a single thought.

But what do we advise the OP now? Are there also sound insulation certificates for single-family houses?

Soundproofing needs to be planned; how much of it you get is ultimately a question of cost. It only has limited relevance to the Energy Saving Ordinance. Timber frame houses are not automatically inferior to solid constructions.

But what do we advise the OP now?

The one stated in #2. However, not with the 2018 version of the 4109, but with the version valid at the time of contract signing/construction.

I would rather be interested in whether this is generally normal with the described setup because then he can save himself the whole thing
