Posting for traffic because I know no one in real life to ask! Our builder mentioned that the large uPVC doors we want (2m gap and opening not sliding, so pretty big and heavy) may catch when shutting due to expansion in the sun and need adjusting and said we might be better off with smaller doors and sidelights. Does anyone have big doors and is it a problem? I don’t mind if we just need to adjust them a couple of times a year, but once weekly would make me rethink!
