Energy Efficient Garage Doors: Are They Worth the Investment?


Every winter, homeowners across Canada crank up the heat in their garage to keep workspaces warm or to make morning commutes a little cozier.

If you have a heated garage and are looking to upgrade your garage door, you might want to consider an energy efficient product to maximize your spend.

Why go energy efficient?

An energy efficient garage door will help to keep your garage warm in the winter and cool in the summer. This is especially important if your space is heated as the hot air may be escaping through your garage door, driving up your energy bill.

If your garage is attached to your home, cold air can travel inside through entryways or vents and contribute to a rise in monthly heating costs.

What makes a garage door energy efficient?

The R-value of your garage door indicates how well the door prevents heat from travelling through it. The higher the R-value, the more efficient it is at regulating the temperature of your garage.

The R-value of your garage door depends on the construction of the door and the type of insulation used inside it:

  • Single Layer: garage doors constructed with a single layer of insulation have little or no insulation and are ideal for use in milder climates.
  • Double Layer: filled with polystyrene (Styrofoam) insulation, double layer insulated garage doors are more energy efficient than single layer garage doors.
  • Triple Layer: providing the highest level of energy efficiency, triple layer insulated garage doors are filled with polyurethane (spray foam) that expands inside the door for better insulation coverage.

For heated garages, Creative Door recommends a minimum of R-11; however, an R-value of 14-16 is ideal.

How do I shop for an energy efficient garage door?

After determining the R-Value, consider the material of the door:

  • Steel

On its own, steel is not a very effective insulator; however, steel doors are available with insulating layers to increase their energy efficiency. If you're interested in a steel garage door, choose one that's been built with two thin sheets of steel and a layer of insulation in between.

  • Fiberglass

Although fiberglass performs well in wet environments, it's not a good insulator and, if exposed to cold temperatures for an extended period of time, it can become weak.


  • Aluminum  

Aluminium is a lighter material that contains two thin sheets of insulation in between two sheets of aluminum.

  • Composite Wood

While authentic wood doors should typically be avoided for use in cold and wet environments, composite wood doors have a higher R-value and can be fitted with a steel overlay for added insulation.

So, is an energy efficient door worth the investment?

Energy efficient garage doors can significantly increase your home's energy savings and year-round comfort. Even if your garage is unheated or only used for storage, a properly insulated garage door will help to regulate the temperature inside and prevent damage caused by freezing or overheating.
