How Insulation Keeps Your Garage Comfortable and Efficient
When you think about where you might add home insulation, the garage is probably not the first place that comes to mind. However, insulating your garage can have a huge impact, whether you simply park your car there or transform it into a workspace. Here’s why garage insulation pays off and which options might be best for different applications.

Why Insulate Your Garage?
More homeowners are adding garage insulation when they realize the many benefits it provides:
- Better temperature regulation: From freezing winters to hot, humid summers, garages in Chicago homes can turn into veritable iceboxes or saunas. Insulating your garage creates a barrier between the outside and your indoor space, making it easier to keep the temperature comfortable—as long as you commit to keeping the garage door closed as much as possible.
- Lower energy costs: An uninsulated garage leaks hot or cold air into the attached house, making your heating and cooling system work harder. Insulating the garage properly reduces those drafts and offers energy savings.
- More comfortable workspace: Do you use your garage as a workshop, home office, or gym? Insulation makes it a functional space year-round, especially when paired with a ductless mini-split for targeted heating and cooling.
- Protection for your belongings: The garage is a common storage space, but exposure to fluctuating temperatures can damage delicate items. Insulation keeps the temperature stable to protect anything sensitive to heat or cold.
Choosing the Right Type of Garage Insulation
Now that you know why insulation is worth it, the next step is to choose the right type for your garage. Here are a few suitable options:
- Fiberglass insulation is a popular, budget-friendly choice for garage walls and ceilings. It comes in batts and rolls, making it relatively easy to install. Keep in mind that fiberglass must stay dry to be effective, so it may not be ideal if your garage is damp.
- Spray foam insulation expands to fill every corner, giving you an airtight seal that’s hard to beat. Spray foam has a higher upfront cost than fiberglass, but it’s more energy-efficient and provides superior temperature and moisture control.
- Rigid foam board is great for garage doors and walls. It’s easy to install, highly effective, and resistant to moisture.
- Reflective insulation controls heat if your garage gets a lot of sun. This insulation type is typically used on garage doors, where it reflects radiant heat back outside. It’s not as effective in cold weather but can help balance temperatures when combined with other types.
