Is it true that wood-aluminum windows in new buildings often crack?
We've been living in a new building for about four months. The outside of the house is not plastered yet. We have very high quality wood-aluminum windows (oak inside and black outside). Unfortunately, the windows are incredibly cracking. Especially in the morning when it gets warmer (just enough to get the sun up) and especially in the evening when it gets a little cooler, and at night (which of course is the worst).
There are 3 types of noises: one is a loud popping noise (now and then), as if the whole window jumps out of the wall; the second type of sound, similar to "burning" on the glass (as if it was hit by a larger insect; it is almost like launching a small fireworks on a table in the apartment, since we have many windows) and the third type is a knock to the wall, like hitting a plastic pipe with an iron bar.
The last problem was solved by covering the outside of the blind box with insulating film (the house is not yet plastered). Otherwise, the other two problems still exist. The window company has already been there four times and removed the glass and put in new glazing units (initially only on 3 windows to see if it works). The "burning" on the windows got better. But the window company won't do anything else.
We have many friends who have wood-aluminum windows (also from our company) and they have no problem. What can we do?

We can't get very far with the window company. It's just hard to prove because it doesn't crack 24 hours straight. And when someone is there, it just doesn't crack. :-( Our site manager just shrugs it off.
Answer
Wood/aluminum is a complicated combination that only a few manufacturers use. If aluminum cladding is inherently rigid, there are inevitable stresses due to different expansion coefficients.
The reasons can be different: different wall materials, different levels of installation, different assemblies.
Most often painted white, there are fewer problems. They don't heat up as much in the sun.
This is most likely due to heating and cooling. It may also be a common design error or the wood is not in working order (too wet or too dry?). Or is it not the window itself, but the louvers?
You have no option but to chisel the window installation company.
