Our currently preferred general contractor offers the Liaplan Ultra 09 as the standard exterior wall, with a wall thickness of 36.5cm (14.4 inches). Can anyone share their experience with this block? I haven’t found any reviews.
Here are the specifications of the block:
For a small additional cost, I could get the Liaplan Ultra 08:
Could anyone provide some input on these? It’s especially important to me that I don’t hear anything from outside once inside the house. For a significantly higher price, I could also get something completely different (e.g., sand-lime brick with external thermal insulation system).
Here are the specifications of the block:

The U-value mentioned in the first post corresponds to the current standard and can also be found with aerated concrete as well as perforated bricks. Therefore, I see no reason why the use of expanded clay aggregate in house construction should be opposed.

OK, thanks. So basically, I can’t really go wrong with the block. It really just comes down to personal preference. As I said, having peace and quiet is important to me. If you say that with a 36.5cm (14.4 inches) block you can’t hear anything (unless you have poor doors or windows), then that’s fine.
Calcium silicate bricks are heavier, so they are probably better for interior walls if you don’t want to hear everything from the next room.
On the other hand, only family members live in the house. So I think you’re less bothered by noise compared to having strangers around.
I just need to decide whether I prefer calcium silicate bricks with a polystyrene exterior insulation, or cavity blocks where the polystyrene is inside the cavities...
