Noisey upvc windows?

Question

My new upvc windows make noises when the sun shines on them. It's a sort of cracking noise, should I be worrried or is this normal?

Answer 1

sounds to me like its the plastic contracting and shrinking, if they have jut been fitted i would allow them a few days to settle, but if you had them fitted a while then i suggest you contact the manufactureres and ask them to be replaced. I hope safestyle didnt fit them as I have waited 4 years for a replacement door window handle and 5 years for a refund for wood sills. Good luck
