QUICK ANSWER
An insulated garage door keeps the garage cooler, quieter, and cleaner. For hot inland cities and garages attached to the house, it is usually worth it.
Insulated doors have foam between two layers of steel. The R-value tells you how well the door resists heat. Higher is better.
Polyurethane or polystyrene?
Polyurethane foam fills the whole panel and usually gives a higher R-value. Polystyrene uses foam boards and costs less. Both make the door stiffer and quieter than a single-layer door. Learn more in insulated garage door installation and our material guide.
