I plan to do this myself, but the question I have is has anyone else done this and does it make that much of difference. The AC salesmen I talked to said it could lower the temperature in the garage by as much as 20*. Living in MN, I know just having your car in the garage during the winter can have that much affect. Just trying to do some fact checking and look for product recommendations.

I had my garage door insulated about 4 years ago with 1.5 " Styrofoam , the kit the insulation company used had extra insulation thus I was able to insulate the wall above the garage door as well , Plus the installers had extra pieces they gave me so I insulated the outer wall around the door - yes it lowered the temperature in the garage by about 18 degrees - very pleased I insulated the door and surrounding wall - which made being in the garage bearable. I would have done it all myself but I had an additional 4" blown in the attic plus radiant barrier added (thus hired out the job a little bit more than I can handle). Living in a patio villa The Villages do not insulate above the lanai or garage - I had both of these areas blown in an insulated as well (just in case I enclose the lanai and the garage just in case I add a split AC unit). Attic temperature was lowered by about 28 degrees when I checked. I noticed my AC did not run constantly. I don't know if it is cost effective proposition - cost about $2500 , saved $3-5 a month in electric bill , and suspect my AC unit will last longer (PS I am probably the only Patio Villa owner with their original AC unit in the neighborhood - still in use after 19 years).
