How to Use Your Garage Door Insulation?

Clean the Door Thoroughly

First things first, make sure that you are insulating a clean garage door.

The point is, if you do not do it, there are chances that dirt and various smudges might be visible on the door’s surface. You might face insulating a dirty door because you will notice weird fragrances from the door, and you cannot use any adhesive on the dirty walls.

Correctly Measure Your Garage Door

Garage doors come in various sizes.

Most users like a custom-built garage door.

So, when it comes to insulating the garage door, the best and most vital thing to do is measure it correctly so that you can get a clear idea of how much insulation will be needed.

Get the Necessary Insulation

You must understand that garage door insulation is not something you will frequently do; hence it should be durable enough to last for years. Therefore, performing poor or half-hearted insulation will harm your space in the long run.

We will recommend you get the best garage door insulation materials and kit that lasts for years, whether it’s foam insulation or any kind of insulation material.

Consider the R-Value

The R-value of every insulation kit is not the same, and it is one of the most vital considerations when buying a garage door insulation kit. The R-value of insulation materials also differs. Usually, the R-value of insulation kits is 3 to 9. If you live in a cold area, go for the kit with a low R-value, and if you live in a hot environment, a kit with a high R-value will do the job for you.

Cut the Insulation to Accurate Sizes

After measuring your door’s size, cut the kit accurately as per your garage doors’ dimensions. Insulating kits come in the shape of individual panels or in the form of coils that you cut into pieces as per the size of your garage door.

Fit the Panels by using Adhesive

Now is the time to fit the cut panels.

You will receive the adhesives with the pack along with the insulation kit. However, there are high chances that you will need additional adhesives. So, keep that in mind and always buy the right and effective glue or adhesive tapes for fitting the panels on your door.

How Many Insulation Materials Are There?

There are different garage door insulation materials in the market. The most common materials used are:


It looks like cloth and features excellent insulation properties. Due to its high flexibility and malleability, fiberglass is mostly used to combine various material pieces into one single unit.

Rigid Foam

Rigid foam is a hard foam, and it is shaped into panels. You can use it immediately. The thing to look out for here is, the thicker it is, and the better it will be for your door.

Spray Foam

Another form of foam insulation comes in the form of a spray. It’s the same thing as the rigid foam, the only difference being that you get to choose where you’re going to spray it on your garage door. Using spray foam means you can be more precise about where you’re applying the insulation foam, but at the same time, it can be quite messy if you’re not careful.


Cellulose is similar to fiberglass in terms of thermal characteristics and the R-value. The main difference is that it includes organic plants, and it is much expensive than fiberglass.

Reflective Insulation

Reflective insulation panels feature aluminum and are usually used in combination with other materials to make the insulation kit more efficient.

What Can I Expect after Insulating My Garage Door?

Adding insulation to your garage door’s channels will keep your space 10 to 12 degrees warmer in cold temperatures and up to 20 degrees cooler in hot conditions. Insulating a garage door also reduces outside, and you will not hear street traffic when working in your garage.

How to Improve Garage Insulation?

Here is some valuable info if you already have an insulated door or plan to perform the insulation. Insulating a garage door will definitely improve your garage’s temperature, but you must think about insulating the rest of your garage space. It will create the best temperature in your whole area. The first thing you must figure out is where you’re losing heat to improve the garage insulation.


Any gaps or cracks can result in the leakage of our and affect your garage or home’s temperature. Here are some crucial areas where you might find air sneaking.

Walls: If you plan to insulate your garage door, ensure that garage walls are also insulated. It will prevent heat from transmitting through the walls.

Ceilings: Garages and home workshops usually have uncompleted ceilings designed with joists and rafters. If that’s the case with you, insulate your ceilings by adding wallboard as it will prevent heat from escaping through the top of your garage space.

Garage door: A garage door without insulation is not recommended as it will allow the heat to pass through it.

So which is the best insulation material for the garage door?

Here we will be comparing the insulating properties of different materials to decide which is the best garage door insulation material in the market.

Here’s a list of common insulators, along with their R-values.

Material with R-value per inch

  • Cotton batts 3.7
  • Extruded expanded polystyrene (XPS) high-density 5-5.4
  • Extruded expanded polystyrene (XPS) low-density 3.6-4.7
  • Fiberglass batts 3.1-4.3
  • Fiberglass loose-fill 2.5-3.7
  • Fiberglass rigid panel 2.5
  • Glass 0.14
  • Hardwood (most) 0.71
  • High-density fiberglass batts 3.6 – 5
  • Home foam 3.9
  • Molded expanded polystyrene (EPS) high-density 4.2
  • Molded expanded polystyrene (EPS) low-density 3.85
  • Open-cell polyurethane spray foam 3.6
  • Polyethylene foam 3
  • Polystyrene board 5
  • Polyurethane rigid panel (CFC/HCFC expanded) aged 5 – 10 years 6.25
  • Polyurethane rigid panel (CFC/HCFC expanded) initial 7-8
  • Polyurethane rigid panel (pentane expanded) aged 5 – 10 years 5.5
  • Polyurethane rigid panel (pentane expanded) initial 6.8

By looking at the table, one can witness that the polyurethane foam rigid panels are the best garage door insulation material as they have 7-8 R-value insulation per inch. However, these panels are more expensive as compared to the other insulation materials.

Moreover, they’re very lightweight and will not affect the working of your garage door. For instance, eight panels of 23.25X54X1.25 inches for an 8-feet garage door will add only 0.77-1.16 kilos.

Over time, polyurethane and other insulation material will lose their effectiveness. Therefore, we will advise you to change them when they start to lose their effectiveness.

Buying Guide about Door Insulation Kits

Here are some guidelines that you must follow when looking for the insulation kit for your garage door so that you can avoid a costly mistake.

Size and Shape

The size and the shape of your new insulation kit and garage door are vital considerations. Mainly because the cutting of the insulation kit is difficult, and before purchasing, you should know the exact measurements of your garage door.


The garage door insulation kit features various materials. The effectiveness and price of all these materials vary as well.

Below are some common materials that are used in the garage door insulation kit:


Fiberglass is a common material, and it is highly durable. Fiberglass insulation kits for garage doors have a high R-value of 7 or above. So, it offers excellent insulation.

However, the major issue with this garage door insulation kit material is that it is not easy to cut off.

Spray foam

The spray foam is a normal foam that people usually spray on the door. After correctly applied, the foam creates insulation between the door and outside spaces. This is the most affordable garage door insulation kit material but not the most effective one.

Rigid foam

Usually, rigid foam features Styrofoam, which is lightweight and provides reliable insulation. The main benefit of this type of insulation is the simplicity of use and ease of installation. Cutting the rigid foam is also simple as compared to the other insulation materials.


Cellulose is a thermal material that is manufactured only from organic plants. According to some experts, Cellulose is much better than fiberglass, and it is simple to install.

However, this insulation kit material’s main downside is that it is costly compared to the others.


R-value determines the effectiveness of the garage door insulation kit. A kit that features a higher R-value is more effective than the one that features a lower R-value.

Usually, the garage door insulation kit with an R-Value of seven or more is enough and offers reliable insulation in any weather condition.

Noise Reduction

Garage door insulators also reduce the outside noises. So, these kits are the best for people who want to block unwanted sounds from entering their premises. But remember, these are not specifically made for noise reduction purposes. So, keep your expectations at a minimum.

Level of Toxicity

This is an essential consideration and should be your top priority. Some, if not all, garage door insulators contain a toxic substance. These are dangerous for your health, house, and the environment. In recent times, garage door insulators feature high-quality fiber or vinyl construction. In these kits, the level of toxicity is at a minimum.

Similarly, you must check out for the certifications and approval from concerned authorities. Toxic substances are harmful to kids, pets, and adults. So, ensure that you are buying a certified and safe product.

Easy to Install

It is the obvious one. Usually, installing a garage door insulation kit is a DIY task, and no one likes to purchase a difficult kit to install.

Luckily, the garage door insulation kits are simple to install, and you can install these kits by using basic tools by yourself.


Here, you should ensure that the doors’ weight does not upsurge due to the kit. If you put additional weight on the door, it will get difficult to operate the door. After installing the kit, check the door’s working, and if you find it heavy, seek the professional’s advice.


Before buying a garage door insulation kit, remember your budget. The high-quality kits are expensive, and you should keep the ceiling price in mind as well.

Garage Door Insulation for Hot Climates

If you want reliable insulation in hot conditions, your best and safest option is radiant barrier insulation. This insulation features two reflective sheets on both sides of a bubbling core.

Conversely, you can also opt for cardboard, but the effectiveness will be much less, and it is not safe.

If installing a radiant barrier, ensure an air gap between the door and the insulation kit. You can do this by cutting off the insulation kit but keeping the strips long enough so that they can reach the floor from the top of the door.
