ᐅ Prefabricated home builders with good sound insulation?

Hello,

I am currently comparing Bien-Zenker, Hanse Haus, and other prefab house manufacturers. The interior walls from Bien-Zenker are covered on both sides with 18 mm (0.7 inches) special gypsum fiberboard, while Hanse Haus uses 12.5 mm (0.5 inches).

Do these thicker 18 mm panels have a noticeable impact on better soundproofing, or not necessarily? Does anyone have good or bad experiences with sound insulation from prefab house providers?

Thank you
Andrez

Every supplier provides sound insulation ratings; for example, Schwörerhaus now offers three levels. We missed that opportunity back then. Personally, I would have liked more soundproofing inside the house; the noise protection to the outside is perfectly fine.

Thank you, I will take a look.

My mistake: Hanse Haus still has an OSB board under the 12.5mm (0.5 inch) gypsum board (so OSB + gypsum board), whereas Bien-Zenker uses an 18mm (0.7 inch) special gypsum board from Knauf.

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

You can completely disregard this kind of Excel pseudo-analysis of cladding layers in terms of number and thickness, theoretical decibel values, and similar nonsense. From a building acoustics perspective, small sound bridges caused by carelessness, missing decoupling, and other construction and processing errors can cause far more damage than theoretically can be compensated for by even the most vibration-damped masses.
The misconception that prefab houses are inherently acoustically weak is only rooted in people’s minds, and nowhere else. If that also applies to your mindset, the only “solution” is to build solidly—according to forum consensus, sand-lime brick is considered the top soundproofing material. Alternatively, you can simply relax and reduce your fears.

Within the limits of what is possible on a “technocratic” level, double-layered cladding can be preferable to thicker single layers—but acoustic engineering is a holistic concept. Trying to improve sound insulation through “single measures” is like tuning a car by only changing the compression ratio or gear ratio individually.

@tomtom79 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 sound insulation values. Also, do you think a better door would make a difference, or are the walls simply too thin?
