I have had a 2-door garage with both doors Insulated from the factory and they were the best thing you could ever do to a garage door.
Much quieter, and the garage is much warmer and cooler when appropriate..
Make sure you get the rubber long gaskets that go between the door Edges and block out all the space that is sometimes there..
Then, you will have a really nice room/s and not just a cold, drafty, garage..
Im thinking the denser the foam the better..
Good luck with this !

I used r11 unfaced fiberglass batting. At the suggestion of a garage door guy I had him upgrade the door springs to whatever the next stronger size was. They were $60 each installed and needed two of them. The opener is 1/3hp. The springs make up for the heavier weight so there is no added stress on the opener.
I sell Liftmaster openers and Clopay doors for a living. If you ever have any questions don`t hesitate to ask.
If you are building a new garage I would do at least steel back insulated doors. They are more expensive, but are a higher quality door. Don`t do glass, it`s never insulated and have to pay a hefty add-on for insulated glass. I have glass and about to replace the glass sections with regular sections because I rather have the insulation. I would also do belt drives if you have any living space above the garage. The belt drives with steel back doors are super quiet. I have two bedrooms above my garage and you never know when they open or close.
Now when it comes to adding insulation to your non-insulated doors. Be careful adding too much weight to some of your doors. Especially insulation that aren`t made specifically for garage doors. It can mess with the spring rates. There are about a million different springs for all the doors available. Every door has specific springs based on their weight and adding weight can throw off the spring or even cause the spring to wear out sooner and possibly break.
I just finished up insulating my doors with foam boards from Lowe`s. Definitely noticed a difference in heat loss and the doors are much more quiet. Well worth the effort.
I just recently had both my garage doors replaced...did a upgrade to Clopay double insulated. ....wow...what a major difference. ..I can actually go in the garage at night and not freeze. ..incredible difference. .
