What is the Best Insulation for a Garage?

Though often overlooked, your garage is actually one of the most important rooms in the house. It gets used several times a day (probably more than your guest bedroom, let's be honest), it stores many of your belongings, and it's likely the most accessible entry to your home. Still, garages get forgotten — unsealed, uninsulated, unprotected. All the time.

Why garage insulation?

What's the point of insulating your living room, only to let all that delicious conditioned air seep right out the garage? Just like crawl spaces and attics, garages — when left uninsulated — fight against the investments you've made indoors.

Whether the area is small or large, finished or unfinished, garage insulation helps prevent heat transfer (hot air going out and cold air coming in) and amounts to significant savings on energy costs. Plus, it makes doing a quick oil change on that concrete floor a whole lot more comfortable. Promise.

Which garage insulation is best?

There are lots of options when it comes to garage insulation, each with their own positives and negatives. While your choice will likely depend on your unique budget, needs and expectations, our team at Ward Insulation believes strongly that spray foam is the best option on the market.

Spray foam is an amazing insulator. Dense, gap-free and extremely sturdy, spray foam keeps wind and moisture out, while keeping temperate air in. It also increases racking strength and lift strength by 150% and 100% respectively. Pretty amazing, especially in windy states like Wyoming and Colorado!

"Spray foam has the highest R-value per inch out of all insulating solutions, sitting at around 7.0," says Ward Insulation's founder and president Carter Ward. "If your goal is to keep cold air and moisture out, there's no better option than spray foam."

How is spray foam installed in a garage?

Spray foam is applied to open cavities of the walls and ceiling to create an air seal. Spray foam expands up to 100 times its original size to fill every nook and cranny in the cavity (gaps that fiberglass and cellulose can't access). It's pretty amazing!
