Additional insulation in garage?

How much did your builder quote you for this?

Now it stays above zero in all but long stretches of -25 or colder.

I would not bother doing this unless you plan on installing some type of heater in the garage. Like an electric heater or small but properly vented gas heater.

Gas proofing rules would not allow your homes furnace to provide heat for the garage.

All this would only be useful if you were to use the space for some type of hobby or wood shop or for a chilly man cave,,,,,,,,,, oh,,, sorry,,, a humankind cave.

One other small advantage to insulating the garage walls and door is the extra bit of noise reduction that'll get you. Not only reducing the amount of noise from inside the garage getting out, but also the amount getting in.
Mine is fully insulated, and when I catch a sale I'll get a small kerosene heater for those rare occasions I want to do stuff in the garage (minor car repairs or messy craftsman-type stuff). But even now, when my spouse parks her car in there, all the ice melts off it and eventually drys up on the floor. I'm going to have to put something in there to better contain that wetness, but it doesn't re-freeze.
I have zero regrets at paying for the extra insulation.
