I'm installing this kit
https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
right now. We have a black, south facing garage door. The garage has insulation between it and the attic and it's a stucco home.
Installation is sorta time consuming but not especially difficult.
The inside of my doors is sitting at 140 degrees right now....on an 80 degree sunny day. The outside of the door in the area I've insulated is an impressive 171 degrees!
Inside, the insulated panels of the garage door are sitting around 91-92.
So dropping the inside door temp from 140 to 92 just seems like a good thing, right?

PS-Customer service with this kit was pretty darn good when I texted with a question....they called back in 5 minutes
