What Is Garage Door Insulation?

PHILADELPHIA - Current times call for more urgent measures to save resources. The power you use daily to turn on your home comes from somewhere. In making your property more sustainable, it’s best to keep investing in items that help improve energy efficiency.


What Is Garage Door Insulation?

One day, we will run out of resources faster unless we all do our part to conserve the environment. You can start in little ways at home. One effective method to do this is insulating your home. Insulated garage doors are available from suppliers and professional services. You can search for a “garage door company near me” on google to have professionals come out and have your garage door professionally insulated.

It is worth mentioning that before insulating your garage, you should verify that all of the garage door system and its parts are in good condition. If you notice that there is something malfunctioning in your garage door, you should contact professionals too. They can perform any kind of repair in your garage door, from a garage door spring replacement to a garage door panel or opener replacement if needed. 

Garage door insulation: definition

What is garage door insulation, and how can you benefit from these doors? Start with these questions to gain more knowledge about these types of innovations to improve your home.

Insulation is any material that prevents heat transfer. In this case, the insulation to a garage door is the property of the door panels to prevent heat from moving outdoors. Insulating material prevents any form of heat loss that results in colder interiors. 

Good insulation is key in maintaining the internal temperature and warmth. Proper insulation makes homes more energy-efficient.

Heat is a form of energy that transfers fast in various mediums. For locations with colder climates, it’s always better to preserve as much heat as possible. Maintaining the warmth causes your heaters at home to work harder and longer, costing you higher utility bills.

Non-insulated doors vs. insulated doors

In terms of insulation, you have two main categories to choose from. Some doors contain insulating materials, and then some doors don’t have any form of efficient insulation

The most basic form or unit of any garage door is its basic, non-insulated structure. You have the entire door mechanism from the rollers up to the opener. You have door panels made from metal, wood, or vinyl material. The insulating material is a customization or accessory you can opt for later.

Insulated garage doors have door panels and door parts with insulating reinforcements. Examples of insulating material are polyurethane material layer or polystyrene material layer on top of the door panel. Fiberglass is also another popular insulating material. Nowadays, there are many ways to DIY insulation. Many DIY insulation kits are available for retail in various establishments.

How do both doors differ? Insulation adds another layer to the panels of the door. Door panels with insulation are thicker or generally larger than the panels without insulation material. Non-insulated doors tend to look or feel simpler and less heavy.

Choosing the next garage door: R-Value

Insulated doors can bring a lot of benefits to your home. However, how exactly do you know if the doors or units have insulation properties? Check the R-value of the information label for each model and brand you inspect.

R-value is the resistance to heat flow. A higher R-value means there is less transmission of heat to the next medium. The higher the numbers, the longer the heat stays indoors, helping your home heater work normally or less than necessary. 

Jumpstart in making your home more energy-efficient for the long run. Always aim for a higher R-value than R-12 for your first commercial door or residential door purchase. 

Should you aim for an insulated garage door?

Depending on the function, you need to consider insulation properties. Insulation helps vastly in places that need to retain as much heat as possible. If you live in areas with higher temperatures, an insulated door may not be as beneficial for you.

Moreover, your step into energy efficiency doesn’t only stop at purchasing insulated doors. It would be best if you dealt with all kinds of leaks inside the garage. Seal all gaps by applying door seals, weather-stripping, and insulating material to holes.


Plan out how to make your home more sustainable. The small steps you take now will benefit you in the long run, starting with investing in good home insulation.
