Non-insulated (single-layer steel)
One layer of 24- or 25-gauge steel. The cheapest option at $1,295 to $1,795 installed. Loud when the door moves. No thermal break. Fine for a detached garage you only use for parking.

Insulated vs Non-Insulated Garage Doors (Chattanooga)
Chattanooga gets 90°F summers and 20°F mornings in January. Most local homes have attached garages that share a wall with a bedroom or living room. That's where insulated garage doors pay you back the fastest.

Insulated (sandwich-build)
Two layers of steel with foam in between. Polystyrene gives R-6 to R-9. Polyurethane gives R-12 to R-18. These doors run quieter. The panels are stronger and resist dents. They keep an attached garage 15 to 25°F closer to your home's temperature. Price is $1,545 to $3,495 installed based on R-value and size.
Is insulation worth it in Chattanooga?
If your garage is attached, used as a workshop, or has a room above it, the answer is yes every time. You'll save energy in the next room. The door will be much quieter. And the stronger panels can stand up to summer hail. For a detached garage you only park in, non-insulated is just fine.
