Insulated vs. Uninsulated Garage Doors: Which Do You Need?

When shopping for a new garage door, the first question you’ll be asked is: “Insulated or non-insulated?” Here is a breakdown to help you decide.

Uninsulated Doors (Single Layer)

These are made of a single sheet of steel.

• Pros: Lowest cost. Lightweight.
• Cons: Flimsy (dents easily). Noisy (rattles in the wind). Zero thermal protection.
• Best For: Detached garages where temperature doesn’t matter.

Insulated Doors (Double or Triple Layer)

These have a layer of polystyrene or polyurethane foam, often sandwiched between two layers of steel.

• Pros:
  • Energy Efficient: Keeps the garage warmer in winter and cooler in summer.
  • Durable: The foam core makes the door rigid and resistant to dents.
  • Quiet: Absorbs vibration and sound.
• Cons: Higher upfront cost. Heavier (requires stronger springs).
• Best For: Attached garages, especially if you have a bedroom above the garage.

The Verdict

For most homeowners in New Jersey, an insulated door is the better investment. The energy savings and increased durability pay for the difference over time.
