ᐅ Request for feedback on various prefabricated house manufacturers

No, other providers sometimes only use a drywall panel without any wood behind it... so it can definitely be worse. We decided against the sound insulation package, and our doors also offer slightly better soundproofing. I’m curious to see how it turns out. We’ll know more in 2 months 😀

What exactly does this sound insulation package include? Does it change the wall or ceiling construction?

Yes, the wall and ceiling structures change. For the ceiling, panels are added that increase the weight and, above all, improve impact sound insulation. The ceiling is suspended from below using spring rails. Schwörerhaus is the only prefabricated house manufacturer I know of that specifies soundproofing performance numerically in the building description.

For the soundproof ceiling, 41 dB (the lower the value, the better).
For the internal soundproof wall, 66 dB (the higher the value, the better). This level corresponds to that of a solid masonry material, e.g., calcium silicate brick.

Except for the topic of sound insulation in the house, but that was my responsibility, I should have booked the soundproofing package back then. Although I don’t believe it's the same with other prefabricated houses having the same wall construction.

The construction "recipes" for walls and ceilings differ only marginally across the industry between manufacturer X and Y. Generally, the interested "consumer" pays far too little attention to the aspect of construction and places too much hope on the materials. However, with sound transmission, the real challenge lies much more in the “mechanical connection” between building components than in the vibration behavior along the transmission chain. Trying to scare unwanted effects away with a material overload only works in a dream. Intelligence is unfortunately indispensable here. The saying "Dem Inschinör is nix zu schwör" means hard to understand, not heavy in weight.

but I believe many companies underestimate what they lose by using poor salespeople or commission-based agents who just try to secure preliminary contracts as quickly as possible.

Companies can rely on the fact that their competitors operate with the same "quality" of customer advisor performers, so they don’t really lose anything, as the scramble for market shares circles back to them. The carousel spins, but the gap between the sports car and the fire truck remains the same every round. As long as none of the competitors realize this, nobody loses ;-)
But at least someone wins through this: the small construction companies without their own marketing department. Their practically best salespeople are those of the flashy brands, whose shameless boastfulness drives customers to places where they actually get help.

I had also seen this at Weberhaus. The exterior and interior walls are fairly similar, but impact sound insulation was better with Schwörerhaus.

Silicone-based paints are not without issues either. They only last a few years before the silicone degrades, and the material is chemically very stable, persisting in the soil for centuries. They are also extremely UV-resistant.

Uh, please correct me if I'm wrong, but you probably mean silicate paints? Those are mostly mineral-based. Silicone is something completely different (synthetic polymers) – are they really used in exterior paints?

No, exterior wall paints with silicone additives. Explicitly.
