If you have a heated driveway, does an extra $1k matter?
What do you do in your garage? Is your garage heated? Do you want to glue a bunch of styrofoam panels to your door?
For me, insulated doors were more solid...quieter, and cooler than neighbors uninsulated doors. No dents from kids balls, crashing their bikes, etc. I was not concerned about cold, but working in the garage during the summer, I wanted cooler.
Maybe you don’t have a heated driveway, and maybe finances are tight.
