After reading through several threads on this topic, I still haven’t figured out which type of block is the right choice for us. Our general contractor prefers to use aerated concrete blocks, but I’m concerned about the lower sound insulation properties of aerated concrete compared to cavity-filled porous clay blocks.
Regarding noise conditions:
We have a corner lot located on a traffic-calmed street and a low-traffic road. The property is in the Greater Frankfurt area, and currently, there is no aircraft noise in the area. Two children are planned.
So my question for the experts:
Am I just being overly cautious about sound insulation, or does it actually make sense to go with the more expensive, heavier block?
Additionally, I’d like to know approximately how much more the structural shell would cost using the heavier blocks (townhouse-style villa, 2 full stories, 9.7m by 10.5m (about 160 sqm (1720 sq ft)), fully brick-built basement).
Best regards

Check with Benz—improving the bricks costs more! That gives you the percentage increase. Add another 500€ for the additional effort to protect the bricks from the weather, and then you should have the price difference. What you won’t be able to find out are the better or worse equity conditions offered by the shell contractor.
In this case, I wouldn’t build monolithically. Both of the mentioned bricks have poor sound insulation due to their low density.
Use sand-lime brick, either with external thermal insulation composite system (ETICS) and plaster or as a cavity wall with facing brick. Soundproofing is significantly better with sand-lime brick.
Edit: I read your post too quickly, soundproofing is irrelevant for you... The type of brick doesn’t matter at all, you won’t notice any difference 🙂
