Are the joints in the partition wall of our semi-detached house okay?

Hello everyone,

today I discovered larger joints in the partition wall (calcium silicate brick) of our new building (semi-detached house).
Is this "normal" or should I complain about it to the construction company?

Thank you very much and best regards

Hello,

you mean the partition wall between the two halves of the house ([Kommunwand])?
To my knowledge, these must be filled with mineral wool for sound insulation. If I am not mistaken, it was 2.5cm ProHaus for me, so 5cm.

I mean the wall (Wand) itself, not the joint between the two semi-detached houses.

Hi,

do you mean because the mortar is missing in the joint? Or because the joints are too large for you?

Regards

The joints are too large with regard to sound insulation.
