Crackling windows when exposed to sunlight

Dear forum members Due to my problem with the new windows, I thought I could turn to you here Ral7016 outside, white inside, ral7016 aluminum top-mounted roller shutter, the rail screwed directly to the windows As soon as the sun comes out, the windows on the south side crack, in the evening when it gets cold as well. The internet is full of people who have the same problem, I find posts everywhere, some years old, but no solution. Does anyone here know anything about this topic? It is truly annoying I would appreciate suggestions for solutions, or reports from those who had the same issue and what the solution was

Hello completely normal, warm and cold. The material works. My wood/aluminum balcony door has now warped as well and I had to have it adjusted.

Hello Hilfehilfe

I'll put it this way. In no previous rental apartment did I have this problem, always plastic windows, but never Ral7016

Of course, dark colors warm up faster, but this cracking noise simply cannot be

And why the window installer, who pretends to be unaware, did not say anything before the sale even though the price difference to white windows was marginal, is beyond my knowledge. But I'll get to that
As I said, maybe there are solutions after all

Dark / black heats up faster though

And why the window maker, who acts ignorant, didn’t say anything before the sale

Because he couldn’t know. Every house is different. There are thousands of houses where everything is fine with RAL7016. An external shading could help. For example, venetian blinds.

Because you would have ignored his concerns and instead ordered the 7016-standard stuff elsewhere where there were no concerns

But white also works and cracks.
