I have metal French style doors

Question

they seem to pop and creak in the morning when the sun starts hitting them. It's very annoying when we're trying to sleep. Has anyone had this problem or know of a solution?

Answer 1

The good thing is that they are doing what they are designed to do.  It sounds like these doors face east and get the early morning sun, meaning that they go from cool exterior side to instant sun and heat, while still being cold on interior.  The doors are sealed properly and they are just moving like they are designed.
