https://a.co/d/0fMkpc1O I ordered this off amazon I lived in south Baton Rouge my garage door faced the sun all afternoon til sunset so it would get really hot didn’t have much for insulation in the attic above it either this helped a ton and having a window that I had a small unit in it that would only run while I was lifting until having to upgrade my home hvac I got them to run me 2 drops to the garage but man the insulation alone is a game changer
