An insulated garage door is the single biggest comfort upgrade you can make to a Chattanooga attached garage. R-13 to R-18 polyurethane doors keep the garage 15 to 25°F closer to your home's temperature. They cut road and opener noise by a lot. And they hold up better against the hail Hamilton County sees every other spring.
**Clopay Gallery Premium (R-18 polyurethane)** — best-in-class insulation with a carriage look.
**Amarr Classica (R-12 polyurethane)** — clean modern style, mid-range price.
**CHI 4250 / 4283 (R-16.4 polyurethane)** — great value with a lifetime warranty.
**Wayne Dalton 9100 / 9605** — wide color choices, both polystyrene and polyurethane options.
