Wood-aluminum windows in new buildings crack very loudly

Hello,
we have been living in our new building for about 4 months. The house has not yet been plastered on the outside. We have very high-quality wood-aluminum windows (oak inside and black outside). Unfortunately, the windows creak incredibly. Especially in the morning when it gets warmer (it is enough that the sun rises) and especially in the evening when it gets a bit cooler and at night (which of course is the worst). There are 3 types of noises: first, a loud bang (occasionally), as if the entire window would jump out of the wall; second, a sound like a "puff" on the glass pane (as if a large insect hit it; it almost sounds like setting off a small table firework in the apartment, since we have many windows) and third, a knocking on the wall, as if someone were hitting a plastic pipe with an iron bar. The last problem was solved by covering the roller shutter box on the outside with an insulating foil (the house is not plastered yet). Otherwise, the other two problems are still there. The window company has already been here 4 times and removed the panes and inserted new glazing blocks (initially only on 3 windows as a test to see if it helps). The "puffs" on the panes have improved. However, the window company now does not want to do anything else. They say that it is normal for windows to creak... We have many acquaintances who have wood-aluminum windows (also from our company), and they have no problems at all. What can we do? Who can we turn to?
Thank you very much.

We have many acquaintances who have wood-aluminum windows (also from our company), and they have no problems at all.

But with a lighter surface, I suppose? - Wood/aluminum is a delicate combination that only a few manufacturers have mastered. If the aluminum claddings are rigid, tension caused by the different expansion coefficients is inevitably to be expected.

That just won't do.

From which company are the windows?

In our current new rental building, we also have wood-aluminum windows.

What I don't like here is that they are really massive, meaning really thick, heavy hardwood windows. Closing them is so stiff and not airy; you really have to apply force. The newer plastic windows from acquaintances, on the other hand, open butter-smooth.

I thought from the headline you wanted to break into your place ^^

There is nothing better than wood aluminum windows, they cost almost twice as much as plastic ones but the look and feel impress me every time anew.

They are not allowed to creak any more than plastic ones, so I would not accept that and continue to hold the window company accountable.

No, well, the other acquaintances also have dark anthracite on the outside. I think that shouldn't make much of a difference. A friend even has the same windows as us (also black on the outside) and he said it creaked at first, but now everything is fine.

Yes, unfortunately that's true.

Yes, the windows look great - no question. I also think nothing should creak, even if the company claims otherwise. The owner of the window company has the same windows in his house and said: Now that I have mentioned it, he relaxed on the sofa and realized that his windows also creak. That would be normal. Is there any place to turn to? We won't get far with the window company. It's just difficult to prove, because it doesn't creak 24 hours straight. And if someone is there, it just doesn't creak at that moment. :-( Our site manager just shrugs his shoulders as well.
