The 10 Best Garage Door Insulation Kit to Buy 2020


Garages often go unappreciated and underutilized. These spaces are beneficial for storage and other things. Even if you don’t use the garage for your car, you likely still use it for some form of storage. When the summer or winter months arrive, you might find yourself going there less often. If you use your garage for keeping stuff like photographs or other things you might later need, you might come back someday and discover that these are damp and falling apart. If you keep tools in the garage, you might also find out they are rusting and going bad. However, this doesn’t have to be the case. A garage door insulation kit is just what you need!

Most people buy a garage door insulation kit in the hopes that it would make their garage space more comfortable in the summer or winter. However, a good number of them soon become frustrated and disappointed when winter or summer arrives. That’s because many of the products on the market do not offer the thermal protection required despite claiming otherwise. It is thus essential to find the best garage door insulation kit on the market.

To help you with this, we have spent time and effort reviewing the scores of these products. After hours of research and testing, we have compiled this review of the best garage door insulation kits on the market today.

When buying a garage door insulation kit, there are several factors to consider. In the main buyer’s guide, we will consider these features. For now, let us consider some of the benefits of buying a garage door insulation kit.

Benefits of Garage Door Insulation Kit

1. Energy Saver

Before installing anything in the home, one of the essential considerations is the effect it will have on energy costs. Well, installing a garage door insulation kit is a prudent course of action. Having a properly insulated home will lead to lower costs as a result of using heating or air-conditioning.

With proper insulation, you are less likely to use heating. Your home will become more energy-efficient and ultimately cut down costs.

2. Protects your garage door

The insulation kit serves as a layer of protection for your garage door. It protects it from the elements, moisture, and other harmful things. It makes the garage door more durable. Many of these insulation kits are solid and anti-dent.

Furthermore, with an insulation kit, you do not have to maintain the doors as often as usual. Additionally, the cold and heat variations will not warp your garage door via expansion and contraction.

3. Soundproofing

Some of the products we reviewed in this post are built to be soundproof. Hence, if the garage is where your teenager’s band practices or you engage in noisy activities there, using an insulation kit will ensure that your garage is soundproof.

By adding this layer, your garage door will absorb more sound. This results in lower noise emissions and will definitely improve relations with neighbors who have always complained about the noise.

4. Protecting your belongings

If the garage serves as a storage space, perhaps where you store photographs or tools, an insulation kit can keep them safe. Even your car will benefit from an insulation kit on your garage door. Cold weather is one of the common reasons why your car’s battery dies. By having the extra heat from the insulation kit, your battery will last longer. Thus, no more frustration due to dead batteries, no more late mornings, and no more shelling out hard-earned money for replacement batteries.

A garage door insulation kit will also keep your garage free from mold, which comes because of moisture.

Guide to Buying the Best Garage Door Insulation Kit

The ten products reviewed above will help you to narrow your choice and assist you in selecting the right garage door insulation kit. In this section, we have provided a guide that discusses some of the features to consider before you make a buying decision.

Type of Garage Door Insulation Kit

There are different types of materials used in making an insulation kit. However, there are four main types. These are spray foam, rigid foam, cellulose, and fiberglass.


This material comes in either rolls or pre-cut panels. The panel style usually has part of it made with aluminum or paper. The importance of these materials is that they prevent vapors and moisture from penetrating the kit and attacking the fiberglass material. It is generally less expensive than the other options available on the market.

Rigid Foam

The rigid foam type is made of large sheets of polystyrene. If you prefer to cut your kit yourself, you will find this type of insulation kit an excellent choice. When done correctly, it offers some of the best insulation performances. However, it is rather difficult to cut into perfect pieces and requires a great deal of precision.

Failure to cut correctly will allow air and moisture to seep through the material.

Spray Foam

Spray foam is a high-quality type of insulation kit. Thus, it is more expensive than the other types on the market. There are two types of spray foam: closed-cell form and open-cell form.
The closed-cell form is more expensive and has a higher reflective value, while the open cell is cheaper but offers a lower reflective value.

It is an excellent insulation kit that offers better thermal control and keeps moisture out better than others.


If you are deeply concerned about the environment, then the cellulose insulation kit is just right for you. It is made from recycled paper and treated to make it fire-resistant.

The efficiency of the kit

Not all garage door insulation kits are made equal. Therefore, some are more efficient than others. A significant consideration that determines the effectiveness of the garage door insulation kit is the R-value. In short terms, the R-Value of a garage door insulation kit refers to the effectiveness of the kit.

A garage door insulation kit with a higher R-Value will be more effective than one with a lower R-Value.

Cost of Installation

Installation is essential when choosing a garage door insulation kit. Depending on whether you want to install the garage door insulation kit yourself or will require the services of a professional, you will have to factor in the cost of installation.

For most of the products we reviewed above, installation is rather straightforward and easy to do. Most of them come with instruction manuals and even the hardware needed to safely and effectively install the garage door insulation kit.

Weight of the garage door insulation kit

If your garage door is an electric model, you have to consider the weight of the garage door insulation kit. A heavy garage door insulation kit will add weight to the garage door and might stress the mechanism of the garage door. To avoid damages, ensure that your opening mechanism is capable of handling the extra weight.

If you notice it would be unable to handle the extra weight, you might have to select another garage door insulation kit, or you can upgrade the opener before installing the garage door insulation kit.

Understand your garage door

Some garage doors are so well-made that they already have all the protection they need. Hence, buying a garage door insulation kit would be a waste of money.

Type of garage door

Garage doors come in different styles and are made of different materials. Hence, you should choose a garage door insulation kit that would complement the door.

Steel garage doors

If your garage door is made of steel, you can rest assured that it can handle almost every type of garage door insulation kit on the market. Fiberglass and foil bubble wrap garage door insulation kit can be inserted into the frames of these types of garage doors. You can also use polystyrene insulation kits on them.

Wood garage doors

For wood garage doors, it might be smarter to have a polystyrene foam style of garage door insulation kit installed. That is because polystyrene foam kits are quite rigid. To create an excellent insulation cover, you can opt to use two layers of foam instead of a single layer.

Garage doors with windows

For garage doors designed with windows, it is smart move adding a layer of sealant and applying around the edges. The sealant will prevent the penetration of moisture. We recommend using polystyrene foam for these types of doors; however, you can choose other types of garage door insulation kits depending on the placement and design of the windows.

Q. How does the insulation work?

There are several explanations for how garage door insulation kit works. However, these are necessary information on how they function.
