Why does nobody talk about glass panels buckling in garage door replacements?
Did a repair where someone put in a single pane of glass too tight in their garage door. When the temperature dropped, the glass pressed against the frame and cracked all the way down. Now the whole door is unsafe until it's fixed. Always leave a small gap for the glass to move with the weather.

Check the frame material too, metal and wood move at different rates so that gap needs to adjust. @bennett.henry is right about the expansion thing, but the frame can fight the glass if you don't plan for both.

Oh man, that's a huge point. It's not just the glass moving on its own like bennett.henry said, it's the whole system fighting itself. If your metal frame and wood wall grow and shrink at different speeds, that little gap can close up fast or get way too big. You have to pick which part you let move and then build for that, or the stress has to go somewhere. Usually that means the glass cracks.

Read a piece by a glazier once that said people forget glass expands and contracts too. That small gap you mentioned is the difference between a proper fix and a call-back.
