"Interior walls are not insulated when building new today"???

[frause]

Condominium from the late 2010s. No insulation in the interior walls. Double drywall makes a clear difference for sound. However, the interior doors are made of cardboard with substantial gaps for air, so it's not exactly soundproof between the rooms.

Shit, seems like I built it all wrong and could have also saved some cash by skipping the insulation in the bargain! 😆

No insulation in our walls either 60s house.

We had single plasterboard uninsulated on a frame structure 45x45 cc 60 in our house from -77. Tore down all the interior walls and replaced with a frame structure 45x70 cc45 with insulation, OSB, and plasterboard. Quiet 👍🏻

Isolated interior walls are not valued by tenants and therefore are not built. If one is to listen to the logic of the current rent-setting system...

On the other hand, all tenants think that electric towel warmers are the cat's potatoes, so you've probably got one of those.

I am just moving into a rental apartment in a completely newly built house. When I gently knock on the interior walls that are framed/plastered, it echoes hollow. I try playing something on my phone, put it down, leave the room, close the door, and note that the soundproofing is nonexistent.

I email a representative of the landlord (whom I imagine is the client of the brand new building) and point this out, and the person replies that "interior walls are not insulated when building new today."

Is this true?

What you can do is check via BBR what sound requirements apply between different rooms, you must meet BBR's minimum acoustic requirements.

Does that really apply within the same apartment? Sound requirements otherwise exist between different apartments.

I guess it's more unusual today, but it's probably mainly about money as usual. Otherwise, I think one advantage at least might be a more even temperature in the home?

They did it well in our previous apartment, with insulation, OSB, and double gypsum in the interior walls between the bedrooms and the bedroom against the living room (Newly built BRF). The doors were unfortunately the same hollow crap as always, so maybe a bit overkill.

Absolutely, there are clear guidelines regarding for example installation noise between the kitchen and living room/bedroom.

Who measures and monitors this in a new production?

 

[FlugfiskarniJämtland]

Who measures and follows up on this during a new construction?

There is usually (not always but mostly) an acoustic description created during the planning, then the acoustician performs measurements when it is completed, but unfortunately, I believe that they most often only perform random sampling of impact sound and transmission measurements just between the apartments.

That's what I suspected, it only applies to multi-family houses, right?

Yes, and LSS accommodations and such. The internal sound requirements according to BBR also apply to small houses, like villas. You can always try sending an email to a consulting firm with acousticians and with some questions, and maybe you can get some quick free advice..
