Wood-aluminum windows in new buildings crack very loudly

No, well, the other acquaintances also have dark anthracite on the outside. I think it shouldn’t be such a big difference then.

So there must be some differences: different wall materials, different installation levels, different assembly, ... - it’s not arbitrary whether it cracks for blue-eyed builders and not for brown-eyed builders.

So we also have wood/aluminum in the combination of white painted pine on the inside and anthracite with iron glitter on the outside. There is absolutely no creaking and normally that would not be the case. It must be related to heating up, is it a local window manufacturer? Since you write that you had direct contact with the boss? Otherwise, you could also contact the manufacturer of the profiles/windows accordingly.

So, we all have blue eyes, so it can't be because of that...
I also think that it must be something related to the house. The only difference I can find at first is that we built with brick and the house is not yet plastered. The others built with pumice stone or timber frame construction and are all plastered.

It must have to do with the heating up, is it a local window manufacturer? Since you said you had direct contact with the boss? Otherwise, you could also contact the manufacturer of the profiles/windows.

Yes, it definitely has something to do with the heating up. Yes, it is a local window manufacturer who has an excellent reputation. That's why it's problematic. Maybe it is also a general construction error or the wood was not in good condition during processing (too wet, too dry?). Or it might not be the window itself but the blinds? Blind guides?
