Hello everyone,
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

Poroton is probably more expensive, and the argument to use the material preferred by the contractor can only be agreed with!
By the way, anyone claiming they can hear the difference between a Poroton and an aerated concrete (also known as autoclaved aerated concrete) exterior wall in terms of sound insulation probably also believes that lemon peelers actually fold lemons!
Regarding sound reduction between rooms, a combination of aerated concrete on the outside and calcium silicate brick on the inside offers advantages because these materials work well together, with calcium silicate being a true absorber of airborne sound.

Use Ytong. At least you can still screw something onto it.Why is it not possible to screw anything onto Poroton bricks?

Use the material that your construction company is most familiar with, meaning the one they usually work with! Proper and precise workmanship is the key. Who’s stealing my mantra here?
