How is insulation beneficial? It provides an extra layer of durability and protection to the garage doors. Insulated garage doors don’t just help in protecting the garage but also its valuables from inclement weather and break-ins. 

Moreover, a well-insulated garage door keeps the garage at a consistent temperature. So, you are also saving your money on energy bills. This energy efficiency benefits the environment.

Garage and Insulation:

If you have a garage affixed to your home, you must get it insulated because the garages with uninsulated doors can affect the heating and cooling system of your house. The system will run continuously, as all the warm and cold air will keep on escaping from the garage door. One should always use the following components in their either attached or detached insulated doors:

  • Insulated Walls: Every wall between your home and garage should be insulated. This also includes the walls of upstairs living spaces. Every wall should be insulated thoroughly and properly.
  • Properly Sealed Doorways: The door between your home and garage and the door of the garage itself should be properly sealed. It must be made sure that there are no gaps for air leakage. 
  • Closed Windows: The windows should be closed and sealed. This will prevent the escaping of air from the conditioner or heat and will minimize energy waste. 

Exciting Benefits of Garage and Century Insulation:

There are several reasons and benefits to having an insulated garage door, including:


Insulated garages almost become soundproof! If you like to make a lot of noise in your garage without affecting your surroundings, insulation will help. Having a workshop in the garage or running an in-home gym can be noisy. Insulated garage doors are thicker and thus reduce noise pollution. Your neighborhood is safe from the noise you want to make in your garage. Other people will not be bothered in other parts of your home. 

The same is the other way around. Just like indoor sounds can’t affect the people outside, external noise can also not reach the inside of the garage. All thanks to insulation, which has prevented the exchange of noises. There is no necessity to worry about the annoying traffic hustle-bustle reaching your garage. The operations of your garage will often be quieter and smoother.


U.S. Energy Information Administration (EIA) has noted that space heating and heat pumps account for about 15.9 percent of residential energy consumption. On the other hand, home cooling accounts for almost 15 percent. The reason for this number is the uninsulated and unsealed garage doors. The warm or cool air keeps on escaping from such doors. This leads to the continuous operation of heating and cooling systems to maintain the temperature. 

In order to gain home efficiency, century insulation is recommended by the Department of Energy. One better insulates everything, from the roof to the base, including garages and the connected walls. You will notice significant energy savings after taking these measures. 


Insulated Garage doors are designed with extra layers of aluminum, wood, or steel protection. That’s why they are much stronger and more durable than uninsulated garage doors. The chances of dent, warp, or rust are very less. Comparing the insulated garage doors with uninsulated, insulated doors typically require fewer repairs. This is because of durability, which refers to more frequent repairs and replacements. 

Popular Types of Garage Insulating Materials:

Insulated garage doors have various types. Each type is based on the different materials being used. The most common insulation material for garage doors are:


Polystyrene is waterproof and a cheap garage door insulation material. It is a synthetic polymer made from Styrofoam. The material can be easily adjusted and customized to fit any garage door.


As said, the cost comes with benefits. Polyurethane is a complex synthetic polymer with higher prices than polystyrene. However, it provides the garage doors with a good amount of thickness. Good thickness leads to more reduction of internal and external sounds. Density is the main benefit of Polyurethane insulation. 

Final Verdict:

Weather Stripping is a long angled strip of rubber and vinyl. It blocks the water and snow from outside. It even blocks the unwanted airflow. Garage insulating and door insulation also include this weather stripping. It is adjusted on the bottom or sometimes on the sides of the doors. Uninsulated doors, on the other side, are not very long-lasting and require frequent repairs and replacement.
