Hello,
we are planning to build our house using unfilled Unipor bricks. Since the plot is in a quiet location, we had no concerns about sound insulation so far. However, a construction company advised me against this because internal noise could also be a problem.
Does anyone have a house built with unfilled bricks? If yes, which bricks and what thermal insulation value do they have? Are there any issues with sound insulation?
Thank you very much!

I don’t have one myself, but many neighbors do. In my opinion, it’s completely unproblematic. Prefabricated wooden houses tend to have more issues with that.

Noise from the inside?
Are you worried that sound from inside will travel outside? What exactly are you doing that is so "loud"?

Seriously:

It's a matter of personal belief.
From a technical standpoint, it’s probably not the best solution.
But a lot depends on your perception. Some say, this is a single-family house where you live with your family—why would you want to isolate yourself? Others say they want peace and quiet and don’t want to hear what the teenagers are up to.
You won’t use the same type of block for the interior walls as for the exterior walls. The exterior wall blocks need to provide thermal insulation. Therefore, they have a lot of air cavities, many chambers, and thin webs, which technically results in poorer sound insulation. For interior walls, blocks with more mass are usually used—meaning less air, thicker webs, and somewhat better soundproofing.
However, the weak points are often not the blocks themselves but their installation, joints, and especially the doors.

Do they think that the rose bush in your garden will wilt if you sing in the shower?

Thank you for your replies.
I understand that sound can travel from inside through the exterior wall, which would make other rooms louder. For example, I don’t want to disturb the child while sleeping when we’re watching TV. Or I want to work quietly in the home office when the child is screaming with joy in another room.

Yes, but this occurs due to poor construction details (such as incorrectly placed edge insulation strips, etc.) and cannot be mitigated even when using top-rated wall blocks. Design flaws cannot be corrected by simply using better materials.
