What is Garage Door Insulation?


Insulation 1

Every view of your garage should have proper insulation, including your ceiling, garage door, and walls. There are a lot of ways on how you can insulate your garage to make it more energy-efficient.

If you don’t always have time for your garage, make sure that you correctly and adequately insulate all aspects of your garage. That’s because it will protect your stored belongings, cars, tools against temperature-related and harsh weather damage. Additionally, an insulated garage door avoids heat loss that could cause a high increase in your monthly power bill.

Furthermore, an insulated garage door can regulate the interior area of your garage. Just like how you insulate your home, garage door insulation will keep the cold and extreme heat outside where it belongs.

So, if you’re living in an area that experiences harsh weather, you should consider insulating your garage door. Before adding insulation to your door, you should check your panels in case you might need a garage door panel replacement. You can call your trusted garage door maintenance specialist to check your panels and add insulation to your door.

How Is A Garage Door Insulated?

Most of the insulated types of garage doors are insulated with styrofoam or also known as polystyrene, which has many varying densities. The thicker the material means that it has more insulation characteristics.

The topmost garage doors use polyurethane that is sandwiched between the layers of steel. This substance is like a liquid Styrofoam inside a spray bottle. If your garage door has cracks, you can easily spray this chemical to seal the fracture on the door. Since the substance is liquid, it could fill the space thoroughly and quickly.

Polyurethane is a chemical that most garage door owners use for superior insulation on their doors. According to NIST (National Institute of Standards and Technology), polyurethane insulation can lessen or block air leakage by around eighty-three percent. It could also reduce your monthly energy consumption by up to forty percent.

In addition, the manufacturers can increase the density of the door to raise its insulation. However, even if you have a three-inch entry thickness, it won’t surpass a thinner door with polyurethane insulation.

More Advantages Of Insulated Garage Door


Unlike non-insulated garage doors, insulated door types are quieter to operate because they reduce rattles, creaks, and add sturdiness. While insulated garage doors can consume vibration and sound caused by running them, it’s vital to consult a professional garage door technician to examine the tracking mechanisms. 

The parts that need to be regularly checked are rollers, chains, springs, and hinges to avoid the irritating sound. A silent garage door operating is advantageous if you use them as the main entryway on your property. Additionally, the thickness of an uninsulated garage door can block the muffling noise from the outside.

More Convenient

An insulated garage door can make you feel more comfortable inside your home or in your garage. It will reduce cold drafts that enter your house and maintain the warm air during hot seasons. If your garage door has a higher insulation property, you can still use your garage throughout all types of seasons. 

Additionally, in case you’ll use your garage area as an extra living space, you’ll need to insulate your ceilings, walls and install drywall. Having an insulated door makes a better place for storage, crafts, hobbies, and your car.


A garage door’s R-value stands for its potential to slow down the transmission of heat. Suppose your garage door has a higher Resistance value. In that case, it means that it has a slower transmission of heat, which indicates you can reduce air leaking to your garage during winter and less heat entering your property during summer.

An uninsulated garage door cannot beat insulated types due to its many benefits to you. So, if you want to reduce your energy consumption, an insulated garage door is perfect for you.
