Garage door insultaion, again

I have seen this asked before, but its a forum, so who knows, maybe someone who asked before has done it and has feedback. I have a 3 car garage, that has three walls exposed, one with windows faces east, one south, and the garage door side faces north. The sun comes up and hits it for a large part of the day, and it gets understandable warm. We live in the south, so it also doesn't cool off much below the 70's at night. I work out in there in the morning, and would love it to not be insanely hot from the day before. I have heard that some sort of garage door insulation will work wonders, but I am also wondering if that wouldn't just... let it still heat up, and then retain the heat better. But I could have a completely wrong understanding of how this all works. Would a decent insulation kit on the doors keep things any cooler? submitted by /u/garciawork [link] [comments]
