Prefabricated house provider with good sound insulation?

Hello,

I am currently comparing Bien-Zenker, Hanse Haus, and other prefab house providers. The interior walls of Bien-Zenker are clad on both sides with 18 mm special gypsum fiberboard, while Hanse Haus uses 12.5 mm.

Do these thicker 18 mm boards actually result in better sound insulation or not necessarily? Does anyone have good/bad experiences with the sound insulation of prefab house providers?

Thank you very much

Every provider has DB values for sound insulation Schwörerhaus for example now has 3 levels. We neglected it back then. For example, I wish for more sound insulation inside the house; outside it is perfectly fine.

Thank you very much, I will take a look.

My mistake: Hanse Haus still has an OSB board under the 12.5 gypsum board (so OSB + gypsum board), whereas Bien-Zenker uses an 18mm special gypsum board from Knauf.

What’s interesting is not only what is on the wall but also what’s inside ;-)

You can completely forget that kind of Excel pseudo-analysis of claddings in quantity and thickness, theoretical decibel values, and such nonsense. In building acoustics, you can mess up more with negligent small sound bridges, omitted decouplings, and similar design and workmanship mistakes than could ever be compensated for by theoretically mass-damped masses.
The delusion about supposedly inherently acoustically weak, barrack-like "prefab" houses exists in the minds only, and nowhere else. If that also applies to your mind, the only "help" is to build massively — the forum majority considers sand-lime brick as the superior number one sound blocker Buddha. Alternatively, you can just chill and turn down your fears.

Within the scope of what is possible on the "technocratic" level, double claddings can be preferred over thicker claddings — but: acoustic engineering is an overall concept, i.e., with "individual measures" you achieve as much here as if you singularly changed compression or gear ratio in car tuning.

Since your last reply in the other section was deleted, I’m taking the opportunity to ask if you have more detailed information about the soundproofing values. And do you think a better door would help, or are the walls just that thin?
