If the sun normally shines on the doors in summer the inside of an uninsulated door gets almost hot to the touch. An insulated door tends to prevent that heat transfer during the hottest part of the day.
This. Think of it like a cooler. if you trap hot air in it stays hotter , hot air Out it stays cooler. I live in South Florida. I leave my insulated door up when its warm until my engine cools off or it gets dang hot in that garage. Regardless having an insulated door is a better option than just a metal door.The thing is.......the heat from your engines will keep the garage warmer in the winter and summer.
I have one like you are looking at, and another garage door that was spray foamed. Both are noticeably cooler than ambient temp even I'm the summerSo we're having two garage doors replaced in the next week, but the existing doors are just the metal door w/o any insulation. Local door company was running a special on their R12.9 doors and we pulled the trigger.
What I'd like to know is how are they during hot summers? I'm sure I will like the garage being warmer during the winter, but do they hold the heat in during the summers? Living in Texas, and obviously not having AC in the garage makes me wonder if I'll end up regretting this purchase.
