What to Consider When Choosing Garage Insulation Materials

There is a fairly large selection of insulation kits to choose from, but the most important part of the kits to consider is what material for insulation they use. Most kits will use polystyrene, fiberglass, or foam core, and the one it uses will help you determine the effectiveness of the insulation, the cost, and whether or not it can be used for your type of garage door.

Any insulation kit you look at should say what its thermal performance score is, which is an indication of how effective the materials in the kit are at insulating your garage door. The US Department of Energy has a good explanation for how insulation scores work — specifically R-Value, which is what most insulation kits will show.

Different materials will have different costs, so if you are on more of a budget you will want to choose a kit that uses more affordable materials. If you do your research into the kits you are considering, you should get a good idea of what is more affordable.

If you have a smaller garage door, you will need to get a different type of insulation kit than if you have a larger one, as some kits will not have enough materials for a garage door beyond a certain size. The type of your garage door (such as overhead or carriage door) will also have a big impact on how big a kit you need, and how much you will have to spend.

Do some research into the garage door you already have, and how much insulation it uses. If your garage door already has some insulation, you will not have to buy a kit that is more expensive and designed for complete insulation. However, if your garage door has little to no insulation or what it had has worn away, you will need to invest in a comprehensive kit to make up the difference.

Types of Garage Door Insulation Kits

When you are researching what insulation kit works best for your garage door, there will be a few different types depending on a number of different factors.

In addition to the mentioned differences in material, there will be a variety of styles, shapes, thickness, cost per size, as well as different life spans, level of durability, environmental impact, and other factors you might want to consider depending on exactly what you want and need.

Make sure that you check the R-value that the kit provides for your garage door, as that is another way that kits distinguish themselves. You will be able to pick between affordable sacrifices and amazing performance.

Carriage-style garage doors with only one solid piece for the door will require a different type of insulation kit than a door with panels that separate as the garage door opens. Similarly, every type of kit will only come with so much material. If you have a bigger garage door, or multiple doors, you will either need a kit that is suited to larger doors or buy more than one kit to make up the difference.

Finally, you can also get different insulation kits depending on the type of insulation you want — if you want a garage door insulated against the heat, or the cold, or both. Kits that work mostly to insulate against heat can be designed to reflect and reduce heat getting through the door, which might not work well at keeping the heat of your home in against the cold.

The Benefits of Garage Door Insulation

Any extra insulation you can achieve with your garage door is a great benefit for you as the homeowner. Improving the insulation in any part of your home can help you save a lot of money over time.

The issue with your garage is that it is likely the biggest single part of your home, with walls and possibly ceilings that touch other rooms. Your garage door is the biggest point of vulnerability for the garage, due to the door being thinner and less durable than the walls. As a result, it is the likely source for any heat and cold getting into the garage, and from there into adjacent parts of your house. This means that your furnace or air conditioner have to work more in order to keep the interior of your home at the temperature you set on the thermostat.

By using an insulation kit and improving your garage door’s insulation level, you prevent more of the heat or cold from affecting the rest of your home. This means your furnace and air conditioner units do not have to work as hard to regulate the temperature of your house. Furnaces and air conditioners are often the biggest source of energy use in a home, especially during the hottest and coldest periods of the year. Since energy use is also one of the biggest regular expenses for owning a home, you can also save a lot of money every month with a better insulated garage door.  

Summary of Choosing a Garage Door Insulation Kit

It is always a good idea to improve the insulation of your home, as you can save a lot of money every month and every year off your energy bills. Improving the insulation of your garage and garage door in particular is important, as it is one of the more vulnerable parts of your home to outside temperatures.

Thankfully, you can greatly improve the insulation of your garage for little cost by using a garage door insulation kit. They come in a variety of types, with a selection of different materials and shapes depending on the type of garage door you have. That way you can pick an insulation kit that works best for your garage door, your home’s climate, and your budget. Check out the complete guide on Home Insulation for Better Energy Conservation on Greener Ideal 

How to insulate a garage door from the inside?

garage door insulation tips

Steel garage doors made of a thin sheet metal have little or no insulation. The houses with rooms above a garage, many times, have problems controlling the temperature. Uninsulated garage doors allow heat to escape in the winter and allow the garage to overheat in the summer. Adding insulation to the steel panels of garage doors can add value and reduce the heat loss of a house. Insulation kits available at construction supply stores or garment door supply companies can be easily installed.


Look for the small insulating strips in the insulation kit for garage doors for the end and center steps. The rungs are the unpainted metal reinforcement supports that give strength to each section of the garage doors. Insert the insulating strip entirely diagonally into the rung. Straighten the strip while pressing it against the rung. Repeat until all the steps have the insulation.

    1. Measure the open space between the rungs and subtract 1/16 inch (1.6 mm) to get the proper measurement.

    1. Using a ruler and the cutter, cut the insulation of the kit of the appropriate size.

    1. Insert the foam into the top cornice of the door panel at an angle. Press the foam until it seats completely in the top slot.

    1. Lower the underside of the insulation towards the door and push it until it is inside the bottom edge of the door panel.

    1. Fold the plastic angles that come in the kit and insert each end at the top and bottom edges over the space between the insulation and the rung. Press the angles inside the top and bottom edges until the angle is flat and one side is in the gap between the insulator and the rung and the opposite is holding the insulator.

  1. Repeat this until all the panels are in isolation.
