An uninsulated garage can be unbearable as temperatures rise in the summer and drop in the winter. While the best garage insulation kits won't create or keep heat trapped, they can retain and dispel it. A layer of high-quality, properly installed insulation will keep heat in and block the cold from penetrating. However, not all garage door insulation kits are great. Some work better than others, while some are easier to install. To make the best decision, we did the research, so check out our top picks for the best options available.

I took several factors into consideration when compiling this list of the best garage door insulation kits. First, I looked for products that were made from well-known brands, such as US Energy Products, a Florida-based company that produces insulation for home and commercial purposes. Equally as important, I chose kits that create a noticeable difference in temperature between the inside of the garage and the outside. After all, the purpose of these kits is to increase comfort levels for those who spend time inside them.
I looked at consumer feedback to see how these kits perform in real-world situations. I also considered the amount of effort it takes to install these kits and avoided those that were more difficult to use and lower quality in nature. Finally, I included kits in a range of prices to accommodate a variety of budgets. For more information on our methodology, check here.

Things to Consider Before Buying a Garage Door Insulation Kit
Garage door insulation kits typically come in standard sizes to accommodate single or two-car garages. However, you will also find products like our Best Value pick, the US Energy Products Double Bubble Reflective Foil Insulation, that is more versatile and can be used for other purposes. As such, you will need to measure your garage door to ensure you order enough of the insulation to get the job done properly.
Ease of Installation
Most garage door insulation kits are fairly simple to use. For example, some products are specially designed for metal garage doors and don't require any tape, glue, or clips for installation. Kits that do require tape or other types of adhesion can vary regarding the quality, quantity, and effectiveness of the tape included. You may need to purchase extra tape because sometimes the tape that comes with the insulation kit is not as effective as it could be.
Garage Door Insulation Kit Pricing
Some garage door insulation kits cost less than $50. These kits or general-purpose rolls of insulation generally accommodate one-car garages. If you have a two-car garage, you will likely have to spend twice as much, or over $100. While these kits may seem a little pricey, they have the potential to provide energy savings and may save you money on utility bills in the long run.
You’ve got questions. The Drive has answers.
Q: What type of insulation is best for garage doors?
A: There are essentially three types of kits you can use: radiant barrier, fiberglass, and foam, and they all work well to insulate a garage. Radiant barrier insulation usually has reflective material along with a layer of air that keeps heat in or out. Fiberglass insulation provides the same type of protection. Still, you have to be careful when handling it because it can irritate your skin and requires the use of personal protective equipment during installation. Another option is foam core insulation, which is lightweight and inexpensive.
Q: How thick should garage door insulation be?
A: Thicker insulation will provide a higher R-value. The higher the R-value, the better the insulation will perform when transmitting heat or cold. Look for products that have an R-value of at least 4 to 8.
Q: What is included in a garage door insulation kit?
A: Every kit is different. Most include insulation panels and some type of tape, fastener, or pins. They also usually include instructions for installation.
