Best Garage Insulation – 3 Great Options For The Heat And Cold

Garage insulation makes your garage usable year-round

Do you find that your garage is always stifling hot during the summer months and absolutely freezing during the winter season? Have you considered garage insulation?

Do you know that garage insulation is the best way to even out those temperatures and reclaim your garage as a gathering spot, a workroom or even an extra living space?

When installed properly, insulation can prevent the garage from becoming a searing sauna in the summer and an igloo in the winter.

To help you understand the benefits of regulating the temperature of your garage, below we will first describe why it’s a good idea to install garage insulation, and take you through the areas in the garage that could most benefit from that insulation.

Finally, we will discuss the different types of insulation that you could use to complete this home improvement project.

What Are the Benefits?

The wide temperature shifts between winter to summer can prevent you from even using this important space in your home.

Moreover, these temperature highs and lows have the potential to damage certain items you may have stored in the garage that require climate control.

Generally speaking, there are three major reasons you should think about insulating your garage. Each of these reasons has great benefit to you as a homeowner. They include:

Temperature Control

If you are tired of climbing in a car that feels more like an icicle during the winter or perspiring profusely every time you need to grab a tool in the summer, you could definitely use some insulation in your garage. Insulation is one of the least expensive ways to normalize temperatures in your garage. With insulation you can once again use your garage as a work space.

Insulation will also make it more comfortable to get in your car, as it will no longer feel like an ice cube or sauna, depending on the time of year.

An insulated garage could also be a safe space to shelter your domestic pets when the weather outside is frightful–Be it winter or summer!

You will not have to run expensive fans or portable ACs in the summertime, and you can finally ditch the space heater in the winter.

Garages can be used as gathering places as an extension of your entertainment area during the holidays; a great workout space where you can keep your fitness gear out of the main rooms, or even the place where your kids’ upstart band propels them to fame.

Financial Savings on Utilities

 

Another great reason to insulate your garage is to save on energy, which translates to more money in your wallet and bank account. 

If your garage is attached to your home, you already know that it can be a notorious energy waster. Because heat and air conditioning is escaping from your home via your garage, those appliances have to work harder to heat and cool your main living space.

That drafty or overheated garage can make you feel like you are flushing your hard-earned money down the toilet.  On the other hand, properly installed garage insulation will let you enjoy great savings as you reap the benefits year-round.

A Soundproof Space

A final reason for insulating your garage is soundproofing. Believe it or not, there are certain types of insulation, such as foam boards, that can actually have a dual benefit when it comes to sound:

It dulls the outside noise and prevents it from getting into your garage, and it muffles the noise from within your garage and keeps it from escaping and disturbing your neighbors.

Do your neighbors regularly have parties, play their music too loud or have rambunctious kids?

No worries, the foam insulation boards you install, provided you buy the correct type, will keep that noise out of your garage—or at least lower the volume.

Do you use power tools in your garage, rev your motorcycle engine, play in a band or just like to play your music loud?  You can do all of these things without a peep from your noise-hating neighbors.

Where Should I Install the Insulation?

Let’s face it, every area of your attached garage could benefit from insulation, but because of the cost, doing a full installation may not be feasible for every family. So where should you start? What insulated area would give you the most benefit?

The garage door

If you are like most homeowners, the garage door should be the first target for your insulation? Why? Because the garage door is where most of the heat and air conditioning from the home escapes and is most susceptible to the outside temperatures.

Garage doors typically have a large space under the door that is exposed to the outdoor elements and conditions.

Moreover, along the sides and atop the garage door are areas that have a similar gap that allow the heat and cold to either enter or escape.

Plugging these gaps with insulation can make a huge difference in the temperature, can save you money on your utility bill, and provide a measure of much-needed soundproofing.

Look online for garage door insulation kits and you just may be surprised by their affordability.

The back wall 

The back wall is the next area in your garage you should address. Have you already guessed why? If you said because it is closest to the house you get a big golden star.

Except for the ceiling, which we will address next, the back wall is the only area of your garage that is directly adjacent to the house.

As such, it makes sense that you would want to insulate that area.

Without insulation, the cold or heat from the garage can easily penetrate your home, making your cooling and heating appliances work so much harder and thus costing you more money every month.

The garage ceiling

The cold of winter can penetrate the ceiling of your garage and make that space feel extremely frigid. And even when you bring in some type of heating device such as a space heater, you are not getting the full benefit from that appliance.

Since heat rises, without insulation in the ceiling, any heat you try to bring into your garage will quickly escape from the top, leaving you cold. This will force you  to increase the heat, which in turn costs you more money.

An insulated ceiling can also go a long way towards soundproofing your garage, as it helps to muffle loud noises from that space thus keeping your neighbors from knocking on your door.

What Type of Insulation Should I Use?

In this third and final section we will talk about the different types of insulation that are available for garages. All of these types of insulation are effective against the invasion and escape of heat and cold in this very useful yet often neglected space.

You may be wondering, “how much garage insulation do I need?” Well, that will be determined once you have decided whether you plan to insulate all of the recommended areas of your garage.

How much insulation you need should to be determined before you head out to Home Depot or Lowe’s to purchase all of your supplies for this project.

Bear in mind, not all insulation is recommended for every area for various reasons.

Here’s a brief look at three types of insulation and an explanation of where you should install it within your garage:

Foam Insulation

This type of insulation is the latest—and some say the best—type of insulation for houses.

Foam insulation is essentially a very carefully mixed blend of chemicals.

When combined and sprayed along walls and ceilings, it expands like foam to form an essentially air tight seal from the outside world.

Proponents of foam insulation say it is the fastest and most effective form of insulation. However, there are a select group of former customers who would definitely disagree.

You see, if the chemicals are not combined properly the resultant foam can eventually give off a chemical-like odor that makes it unsafe to inhabit the house. These cases are rare, but worth considering.

Are you thinking, “how much does garage insulation cost?” Well, let me just say that foam insulation can be very expensive—in fact it is the costliest form of insulation on our list.

If you have the extra cash and do not mind the risk, this could be a very effective way to insulate your garage ceiling.

Fiberglass Insulation

Now here’s a type of insulation with which you are no doubt most familiar. Usually pink in color, these large bundles of insulation are covered with paper on each side to make it easy to handle the bundles.

For decades, this has been the go-to solution for keeping the heat and cold in and out, respectively.

Fiberglass Insulation has also proven to be quite effective. This is the type of insulation we recommend in the ceiling of your garage because it is designed specifically to fit within the studs that are built 16 on center. Also because this insulation will be up in your garage ceiling, it will not be an eyesore.

Fiberglass insulation in your ceiling will address two very big problems: It can help regulate the temperature of the space and save you money in the long run.

Foam Boards

Last but not least, foam boards are the best option for insulating the walls of your garage, including the garage door. Foam boards are a very affordable type of insulation and they are very simple with which to work. They can be nailed directly to the studs of your garage, and because they are so lightweight, you can do the job yourself.

These foam boards check every box in terms of the benefits for insulating a garage because they:

  • Help prevent wild fluctuations in temperature
  • Save you money in energy costs, and
  • Muffle sound both within and outside the garage—a prime benefit that is not really offered by the other two types of insulation.

With this information at your disposal, you can now appreciate the many benefits that come with an insulated garage.

Here’s a bonus motivation: An insulated garage could double as separate living quarters.

Having unexpected house guests? or are your adult kids moving back in? Now you have a nice comfortable climate-controlled room for them to crash.  Plus it won’t cramp your style by overcrowding your personal space.

Now that you know you have options, which of these insulation choices would best suit your personal garage needs?  If you are aware of other cost-effective insulation options, feel free to share in our comments section.
