This is the answer to the question Is it true that wood-aluminum windows in new buildings often crack?
Revision 1
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.
