6 Best Garage Door Insulation Kits – Reviews & Buying Guide
For most people, the garage door is responsible for heat loss during winter and heat gain during summer. This is because most garage doors are made from metal that conducts heat better than the rest of the garage.
Therefore, during a hot summer day, your garage’s temperature will quickly rise because it absorbs heat from the outside.
The same scenario happens during winter time as your garage door will lose heat quicker. Thus, you will need more power to heat up your garage which translates to a bigger electricity bill.
Luckily, the solution is quite simple!

How to Buy the Best Garage Door Insulation Kit
Before finding the best garage door insulation kit for the money, there are some important aspects that you need to consider.
Here are some guidelines you can follow when purchasing this kit so that you do not make an expensive mistake.
#1. Size and Shape
The size and the shape of both the garage door insulation kit as well as your garage door are important factors to consider.
This is because it is often difficult to cut the insulation kit to shape so you must make sure that it fits your garage door right away.
In addition, most garage doors use standard sizes. So, if you pick the right model of your insulation kit, you will have no difficulty installing it on your garage door.
The garage door insulation kit is made from many different materials. Therefore, they have different prices as well as different levels of effectiveness.
Here are some common build construction materials that you will find in your garage door insulation kit:
Fiberglass: Fiberglass is a common construction material used in the garage insulation kit. It is very durable and has a high R-value of usually more than 7 which means that it will offer you with excellent insulation.
However, the main caveat with a fiberglass garage insulation kit is that it is difficult and messy to cut to size so you must make sure that you get the right size from the get-go.
Spray foam: As its name suggests, the spray foam is simply a foam that you spray on your garage door. Once applied, and cured, the spray foam will act as an insulation between the outside and your garage door.
This type of insulation is not the best insulation for the garage door, but it gets the job done and is one of the most affordable.
Rigid foam: The rigid foam is usually made from Styrofoam. Styrofoam is a very lightweight material that offers excellent insulation.
But one of the biggest advantages of rigid foam is its ease-of-use and ease of installation.
Even if you get the size wrong with a rigid foam insulation kit, you will have no difficulty cutting it to size and placing it on your garage door. You can use a regular adhesive to stick it to your garage door.
Cellulose: Cellulose is a low thermal material made from organic plants. Some experts argue that it is better than fiberglass as an insulator and easier to manipulate and install as well.
However, the main caveat with a cellulose garage insulation kit is that it is usually more expensive when compared to other types. Especially if you have a large garage door, then it can quickly become costly.
The effectiveness of the garage door insulation kit is measured in its R-value. A model that has a higher R-value is usually more effective than a model that has a lower R-value.
For most people, the garage door insulation kit with an effectiveness of 7 or more is more than enough and will provide your garage with adequate insulation from both heat as well as cold.
#4. Easy to install
Of course, since installing the garage door insulation kit is usually a DIY job, you do not want it to be very difficult to install.
Luckily, most garage door insulation kits are quite easy to install, and you will need only basic tools to do so. Not to mention that you also do not need a lot of experience to install this kit.
The garage door insulation kit really does a good job insulating your garage, both during the winter as well as in the summer.
But best, this kit is very easy to install, and you do not need advanced tools to do it. You can easily install it over your garage door in a few hours.
It is also relatively affordable, and anyone can purchase a garage door insulation kit without much trouble.
