Insulating Garage Doors

[astroracer]

I used 3/8ths thick P2000 on mine. Just overlayed the whole door and screwed it on with drywall screws and plastic washers. This stuff is great! The door temp went from about ambient outside to the same temp as the shop on the inside... I have pics on Garage Journal. Do a search and look for astroracer. I can't get to the site at work so, if you can't find it, I'll load a pic tonite.
