Types of Garage Door Insulations

Certainly, there are many brands and models of two car garage door insulation kits. However, all of them can be classified into 4 main groups, according to the material they use. So, there are lots of types of garage door insulation kits available on the market. Below, you’ll find a detailed explanation of each type of insulation for garage door. And each type of insulation is perfect for each type of garage door. Example: car garage door insulation is one type. Here’s the full list:

  • Cellulose insulation
  • Spray foam insulation
  • Rigid foam insulation
  • Fiberglass batt insulation

Cellulose Insulation

Certainly, it’s the most environmentally friendly option. So it’s a mixture of recycled paper, fire retardant and adhesive liquid. The mixture is blown directly on the garage door surface, using a blowing machine. Although it’s an ecological and cheap option, it isn’t exactly the best insulation for too high temperatures.

Spray Foam Insulation

Spray foam is applied with a spray gun. The gun sprays two different components that, when mixed, harden, forming a porous surface. The air that passes through the pores helps dissipate heat and prevent heat transfer.

Spray foam is very resistant and is ideal for insulating very small spaces, where noise and heat can pass.

Rigid Foam Insulation

In these cases, the material comes in the form of rigid panels. These panels provide superior insulation in contrast to other flexible materials. They’re easy to install and usually come in standard dimensions. However, you can easily cut them. A utility knife is the best tool for cutting insulation boards.

Before buying, it’s convenient to check the combustion temperature of the material. If insulation to your garage door exceeds that temperature during a hot summer, it’s better to choose something more resistant.

Depending on the characteristics of its cells, foam insulation can be:

  • Open cell foam
  • Closed cell foam

In open cell foam, the cells or pores are open, to allow free air circulation. While the air moves, the heat dissipates. This material is very lightweight, but its R-value is lower than closed cell foam.

In closed cell foam, the air is trapped in small bubbles. Such is the case of bubble wrap. The air prevents heat transfer from the external to the internal environment and vice versa. Its R-value is much higher and better resists high impacts.

Fiberglass Batt Insulation

It’s the most commonly applied insulation type in garage doors. You can buy this product in the shape of pre-cut batts or rolls. Fiberglass filaments can spread through the air. They can cause serious respiratory complications when inhaled.

To prevent this, fiberglass insulation comes coated with aluminum foil, which works as a barrier. Fiberglass insulation is very light and easy to install. But, during the process it’s advisable to wear protective equipment to avoid direct exposure.

Among all insulation types, certainly fiberglass insulation is the cheapest option of all. So, it should be your first choice if you aren’t willing to spend too much money on your garage door insulation kits.

So, depending on the characteristics of your garage door, the temperature of the place where you live and the money available in your budget, you should choose the most convenient option for you.

Buying Guide: Garage Door Insulation

Due to climate change, winters are getting colder and summers even hotter. The transfer of the extreme cold and heat from the exterior to the interior of your home can greatly affect the comfort level. In addition, it can even put your family’s health at risk.

Therefore, it’s advisable to use insulating materials on doors and windows to minimize thermal transfer. The larger the area, the greater the transfer. And certainly, there’s no bigger door in your house than your garage door.

Many garage doors directly face sun’s rays. So, if the door is metal, it will turn your garage into an oven. On the other hand, a garage door without insulation will turn your garage into a refrigerator during extreme winters.

So, you need to choose an appropriate insulator that maintains a comfortable temperature inside your home and doesn’t add too much weight to your garage door. Here you’ll learn everything you need to know to choose the most appropriate insulating material according to the characteristics of your garage door.

R Value

The R value is a number that describes the ability of a given material to resist heat flow. While the R value is higher, there’s less heat transfer through the material. The high R value also depends on several factors, such as the physical and chemical properties of the material and its thickness.

By nature, there are many materials with excellent insulating properties. However, many aren’t appropriate to insulate best garage doors for the money, because they add too much weight. So, this could interfere with the normal operation of the garage door opener.

Therefore, garage door insulators must have a high R value and also be lightweight. Certainly, the best insulators for garage doors are polyethylene, polystyrene, polyurethane and fiberglass. Some insulation types include layers of aluminum on both sides to reflect radiant heat and prevent overheating.

So, in a nutshell, the main function of a garage door insulator is to prevent heat from entering during the summer and escaping during the winter.


The thickness of the material also significantly affects its insulating properties. The usual thickness for garage door insulation panels can vary between 0.3-1.25 inches. As said before, the thicker the material, the better.

However, an increase in thickness can also imply a considerable increase in weight. So, adding more weight will make your garage door opener move slower and get stuck sometimes.

So, it’s good to choose light and porous materials. The air that runs through the pores naturally dissipates heat without adding extra weight to the garage door.


As stated before, the R-value of a given material also depends on its chemical and physical characteristics. So, considering a constant thickness of 1 inch, it’s possible to compare the insulating properties of different materials to determine which is the best of all.

Here’s a list of several common insulators with their respective R-values ​​per inch.

As you can see, brand new polyurethane foam rigid panels are certainly the best insulators for garage doors, providing 7-8 R-value insulation per inch of thickness. However, it’s also true that these panels are more expensive compared to other flexible materials.

In addition, they’re very light and don’t interfere with the normal operation of garage door openers. For example, 8 panels of 23.25X54X1.25 inches to cover an 8-feet garage door only add 0.77-1.16 kilos in total.

Over time, polyurethane and other similar materials tend to lose their insulating properties. As you can see in the table, polyurethane foam rigid panels decrease their R-value to 6.25 after 5-10 years of use. Therefore, it’s convenient to replace them when they lose their ability to resist thermal transfer.

Garage Door Insulation Kits for Installation

Garage door insulation kits are also very easy to install. So, you don’t need too many tools during the process. With just adhesive tape, scissors and screwdrivers, you can do the job for yourself in less time than you imagine.

However, certain materials may be more difficult to cut and handle, complicating the installation process a bit. Such is the case of fiberglass. You’ll also need to wear a face mask and protective lenses, because the fibers of the material can cause a sore throat and other complications when inhaled.

Insulation rolls are usually cheaper than kits, which is very convenient when you don’t have too much money. However, you need to make precise cuts to avoid material waste. Also, they become harder to cut when they’re thicker.

Therefore, to prevent complications, it’s better to opt for kits with pre-cut panels. In this way, you won’t run the risk of hurting yourself or inhaling toxic substances during the cutting process.

Also confirm the panels match the garage door sections, so the door can bend smoothly when opening or closing.

In addition, the instructions should be easy to understand, so you don’t have problems. If other buyers have complaints about the installation process of a certain kit, it’s better not to buy.


High density materials usually have better insulating properties. They’re good at resisting the transfer of sound and heat from the external environment. So, matching material densities is a good way to compare the quality level of different insulation kits.

For example, if two products use polyurethane foam panels as insulators and you want to know which one is the best, simply compare their densities. So, the product with the densest material will certainly perform better.

However, the density of the material isn’t always a determining factor on insulation. Some thinner and lighter materials offer superior insulating properties at a lower cost. Such is the case of bubble wrap.

Bubble wrap is a plastic material commonly used to pack fragile items. Over time, manufacturers discovered the potential of the product for insulation purposes. Air bubbles help dissipate the temperature on the hot side and also prevent heat transfer. Bubble wrap used for insulation is also thicker and its two sides are covered with foil.


Certainly, you must be wise when choosing your garage door insulation. And the color can seriously affect the general lighting of the garage. For example, some materials are very dark and opaque, making your garage look darker than normal. So, if you don’t want your garage to look like a cave, stay away from dark tones.

On the other hand, light tones like white, help you get the most out of artificial garage lighting. The same goes for reflective foam core garage door insulation materials, such as aluminum foil. These work like a mirror, reflecting the light on different points of your garage.

Also, the texture of the surface can affect the reflection of light. Materials with too much texture make light reflection difficult, also affecting lighting. So, it’s better to choose a material with a smooth surface, for example, those garage door insulation panels covered with white vinyl.


Insulation materials on garage doors tend to capture dust and particles dissolved in the air. But, some materials can trap more dust than others. For example, glass wool. Therefore, most modern garage door insulators include an external layer of vinyl or foil.

These layers provide a nonstick surface. This also allows an easier cleaning and prevents dust from entering the material’s pores. To ensure complete cleaning and disinfection, you should only immerse a dry cloth in a solution of water and detergent and pass it on the surface.

Also, the outer layer must be water resistant and prevent the proliferation of pathogens.

Fire Resistant

Above all, the material you choose to insulate your garage door must be fire resistant. If you have metal garage doors facing directly from the sun’s rays, the metal will reach temperatures so high as to burn the material.

So, before buying any insulation kit, investigate the properties of the material and its combustion temperature. Then check the temperature of the garage door surface during a hot summer afternoon with an infrared thermometer.

If the recorded temperature is very close to the combustion temperature of the material, it’s better not to buy. The combustion of insulation materials can release toxic gases into the atmosphere, potentially fatal to certain people.

Non Toxic

Also, the insulation material you choose shouldn’t be toxic or cause side effects on your health. Certainly, fiberglass is one of the best garage door insulators. However, it’s also true that direct exposure with its fibers can be dangerous.

People exposed to fiberglass may suffer skin irritation and lung infections. It’s also presumed that inhaling the fiberglass filaments dispersed in the air can cause fatal diseases. However, there are still no studies to prove it.

However, to prevent this risk, it’s necessary to seal any exposed fiberglass surface with a waterproof material. So, if you’re going to use fiberglass to insulate your garage door, make sure there’s no exposed remains of the material.

Well-Known Brand

When it comes to garage door insulators, it’s always convenient to choose a well-known brand. Insulation products must comply with International fire and health regulations to ensure they’re safe.

For example, well-known garage door insulation manufacturers are required to comply with local regulations to legally sell and distribute their products. Therefore, it’s more convenient to pay more for a product from a recognized brand, than to save some extra money on something generic.

On the other hand, generic garage door insulators don’t indicate what regulations they obey. Nor are they certified by any public organization. In some cases, the box doesn’t reveal the materials used or the manufacturing details.

So, if you notice these suspicious details in the product you intend to buy, stay away to avoid a big disappointment.


Certainly, you don’t need to be an expert to choose the best garage door insulation. If you aren’t sure which product to buy, it’s convenient to take a look at the reviews that other buyers publish on the web. Most manufacturers and sellers only talk about how good the product is, but they don’t mention its defects.

So, it isn’t good to believe in everything you read on the Internet. Remember that sellers will do whatever it takes to keep your money. So, be sure to check first the product quality to make the best investment.

First of all, visit several shopping websites and determine if the general opinion of the buyers about the product is good or bad. If most people are satisfied with what they bought, you may take the risk and buy. However, if most reviews are bad, it’s better to consider other options.

Also make sure the product rating is higher than four stars. In addition, always opt for sellers with many sales. Buying products from new sellers may be a risk.

If you have serious questions about the product, you can ask to other buyers. Many shopping websites have public forums where users can share their opinions and help other people. So, this is a good way to get the answers you need.


Finally, when you’re sure of what you want to buy, it’s time to compare prices. To do this, it’s convenient to visit physical stores and check out various shopping websites. Never choose the cheapest or most expensive option.

If possible, determine the average value of all prices and choose the option closest to that value. Also, consider how much money you’re willing to invest. So, if you’re going to spend a lot of money, make sure you buy a genuine product and not a cheap copy.

Also make sure the product comes with a refund warranty, that way you can get your money back if you aren’t satisfied with the results.

It’s also a good idea to visit the official website of the manufacturer. Some well-known brands have their own online stores where they sell their products at factory prices. Certainly, buying directly from the factory guarantees your peace of mind. You won’t feel worried fearing receiving something totally different from what you ordered.
