Insulated Garage Doors

Control the Temperature of Your Garage & Cut Your Energy Costs with an Insulated Garage Door

Garages have become more than just a shelter for our vehicles. Both residential and commercial garages can be used as added security for our property, storage for our possessions, an extension of our house or business, and even a workshop or place to decompress. With so many uses, it has become even more important to ensure it is temperature regulated.


Insulated garage doors can be a game-changer when it comes to maintaining a comfortable and energy-efficient home. Far beyond just keeping your garage at a pleasant temperature, these specialized doors can actually have a significant impact on your overall home climate and utility bills.


The secret lies in the insulative materials used within the garage door itself. A standard, uninsulated garage door is essentially just a hollow shell – it provides little to no resistance against the transfer of heat and cold. This means that on hot summer days, the heat from outside will quickly seep into your garage, making it uncomfortably warm. In the winter, that same lack of insulation allows cold air to infiltrate the space, causing it to feel frigid.

With an insulated garage door, your garage is much better equipped to maintain a stable, comfortable temperature year-round. This has a few key benefits:

  • Reduced Energy Costs. By preventing unwanted heat transfer, an insulated garage door helps minimize the amount of energy needed to heat or cool your garage. This, in turn, reduces the overall load on your home’s HVAC system, resulting in lower utility bills.
  • Improved Home Comfort. When your garage is better insulated, it’s more likely to act as a temperature buffer between the outdoors and the rest of your home. This means the main living spaces stay at a more consistent, comfortable temperature, even as outdoor conditions fluctuate.
  • Enhanced Garage Usability. A well-insulated garage stays warmer in the winter and cooler in the summer, making it a much more pleasant and usable space. You can use your garage for hobbies, storage, or even as a workshop without having to battle extreme temperatures.

When shopping for an insulated garage door, pay close attention to the R-value. This number, typically ranging from R-6 to R-18, indicates the door’s thermal resistance and insulating capabilities. The higher the R-value, the better the insulation performance.

The optimal R-value for your home will depend on your local climate and the level of temperature control you’re aiming for. In general:

  • Mild climates may only require an R-6 or R-8 door.
  • Moderate climates often do best with an R-12 to R-16 door.
  • Extreme hot or cold climates typically call for an R-16 to R-18 door for maximum insulation.

Other factors to consider include the door material (steel, wood, or composite), the number of insulation layers, and any additional weather-sealing features.
