6 Things to Consider Before Insulating Your Garage

Garage insulation and all you need to know

If you have a natural flare for cars and fixing them, your garage is your escape zone. But your garage consists of stale air, an overheated environment and perhaps, the deadliest germs in the dirt and grease. So, if you’re spending hours on end breaking your back in your garage, you definitely need insulation to maintain a healthy environment.

Sealing sources of air leakage and insulating your garage will ensure an eco-friendly environment for you and your family. This is because you will be able to prevent loud noises as well as harmful gases from penetrating inside your house.

Steps to follow before insulating your garage

Remember that your garage is a private place and does not necessarily have to look as fancy as your drawing room. Most of the times, even our family members will avoid coming to this part of the house – unless they are as car-crazy as you are.

In a nutshell, it doesn’t matter how pretty your insulation looks, as long as it works!

Let’s take a look at the insulation guide book.

Deciding the type of insulation

You must make up your mind on what type of insulation your garage needs. If your garage is still under construction and you have access to the pole barn, you are advised to buy fiberglass batts as they are cheap and efficient. If your garage has existing walls, it is suggested you go for blow-in insulation which works just fine for the low amount of money you pay for it.

Preparing a to-do list will help you keep track of all your necessary products and save you from making a double trip to your store.

R-Value of your materials

Where do you live?

What is the climate of your region?

What is your budget?

The R-Value of your materials will be determined by the answers to each question. The R-Value is basically a measure of the strength of your insulation. The higher the R-Value, the better your garage insulation is.

Cleansing the area

Garages are usually littered and cluttered with tools, cans of products, and by-products of your laborious work. Get rid of everything to prevent a harmful reaction. Also, clean the walls, vacuum dust particles and wipe the walls to allow easy adherence of insulation where required.


You will receive supplies, or you should buy them, with your DIY kits.

  • If you are buying a fiberglass batt, you must purchase a stapler.
  • If you are buying a spray foam blown-in insulation, you must buy a spray hose.

Follow the directions

Carefully read the instructions and directions behind the DIY insulation kit and follow them step by step.

Final touch

Once the insulation has been firmly put in place, inspect the area for any crevices that you may have missed. If you find any, cover them up with the leftover insulation material.

Follow the proper guide in order to successfully excel at installing insulation in your garage all by yourself!
