How Thick Should a Garage Door Be?

One feature to consider when looking for a new garage door is its thickness. Garage door thickness matters since it affects insulation and noise barrier abilities. Read more about the average garage door thickness to decide if your home needs a standard garage door or would benefit from an insulated garage door. 

Standard Garage Door Thickness

The average garage door thickness is 1 3/8 inches to 2 inches, which provides a good amount of separation between your home and the outside. Residential garage doors have this thickness due to the materials they’re made of. The more layers in the garage door, the thicker it is.

Residential garage doors use 24- to 27-gauge steel, with 24-gauge being thicker than 27-gauge. You can choose different layer levels, including:

  • Single layer: Single-layer residential garage doors have a 24- or 25-gauge steel layer.
  • Double layer: These garage doors have a 24- or 25-gauge steel layer with polystyrene insulation.
  • Triple layer: The three layers include a 25-gauge outer layer, an insulation layer and a 26-gauge inner layer.

Uses for Thicker Garage Doors

An insulated garage door’s thickness is greater than a standard garage door’s thickness. Garage door insulation determines how well it keeps sound and extreme temperatures out of the garage. Thicker garage doors have better insulation and noise dampening abilities due to having more layers. Thick garage doors include styles with double or triple layers and thick gauge steel. 

In some cases, having a thicker garage door is beneficial. Instances when thicker doors are advantageous include:

  • Cold climates: Since winters in Chicago can get quite cold, having an insulated garage door helps your home stay warm by keeping the outside air from transferring through the garage door.
  • Extreme heat: Your garage can get quite hot during Chicago summers, making your air conditioning system work harder to compensate for the heat that transfers to your home. Insulated garage doors keep garages from getting too hot and straining your A/C.
  • Attached garage: Thick garage doors improve energy efficiency by preventing the outside climate from affecting your home’s temperature. This energy efficiency can lower your energy bill.
  • Frequent garage use: If you use your garage frequently, a thicker garage door may be more durable. Some garages store tools for home repairs or lawn maintenance. If these tools accidentally hit a thick garage door, it’s less likely to leave a dent, eliminating the need for a replacement or repair.
  • Home security: Insulated double-layer garage doors are more tamper-resistant than non-insulated single-layer garage doors. This tamper resistance makes thicker doors more secure, which is ideal for preventing unauthorized entry into your garage or home.
