Why should I insulate my garage?

Australia is an incredible place to live for so many reasons, but the climate can cause some serious headaches when it comes to keeping your home comfortable, and your garage is no exception. Anyone with a closed-in garage will tell you that you can barely breathe in the hot, stuffy air in summer, and it becomes an ice-box in winter.

Any uninsulated garage can have a big impact on your vehicles and garage items, but it creates an even bigger problem when it’s joined to your home. 

If your garage is attached to the side of your house, especially if you have a room above it, that garage is funnelling heat and cold into your house and making your heating or cooling work double-time.

We’re willing to bet you haven’t given garage insulation much thought until now—but there is a lot to love. Let’s dive in.

Keep your home more comfortable

Any home that’s attached to an uninsulated garage will be impacted negatively, but if you live in a home with a room over the garage, the effects are much more noticeable. Every time someone opens that internal garage door, you get a blast of freezing (or hot, stuffy) air. And if it’s a bedroom over your garage, it’s like sleeping on top of a refrigerator in winter. All that cold air comes straight through the ceiling/ floor, costing you a lot in energy bills.

Lower those energy bills

Proper insulation is really an investment in the future in so many ways, and insulating your garage is no different. As with any insulation, you will see a quick and dramatic rise in your comfort at the same time as a drop in your energy bills. Win/ win.

Make your garage a useable space

Through those freezing winter months, your (uninsulated) garage mainly acts as an ice-shed for your car—you probably drive in, park, and race into your warm house as quickly as you can. But with the proper insulation, you can regulate the temperature 365 days a year, and your garage can work smarter for you, creating a habitable space that you can use all year round. Whether man-cave or she-shed, I think we could all use a little getaway sometimes!

It’s good for your cars

Depending on where you live, storing your car in a cold garage can actually affect its performance long-term. Those icy temperatures can lead to brittle windshield wipers, thickening of essential car fluids, and even negatively affect your car battery. Some well-planned out garage insulation can take care of all these issues, saving you money in the long run.

It also keeps the inside of your car much more comfortable—no more freezing hands on the steering wheel or bums on frozen leather seats!


So what is the best type of insulation for garages?  

Foil Insulation is an efficient and effective way to improve the thermal efficiency of your home and is a great option in your garage.

Foilboard® Green is a versatile, rigid insulated panel designed for walls, underfloors and roofs, and has been engineered to ensure quick and easy installation.

The non-itchy, fibre-free rigid panel is suitable for residential, commercial and industrial applications, and will provide continuous thermal performance for the life of the building.

Envirowall can also be installed between the garage and home for extra protection from the elements.

We recently installed wall and ceiling insulation in a home in Berwick, and during our initial assessment of the two-year old home we found it was under-insulated.

The homeowners were extremely uncomfortable, even on a mild sunny day, and the owners said their second storey was “unliveable” for some months of the year.

After a free assessment, we topped up their ceiling insulation, retrofitted Envirowall cavity wall insulation, added Jetstream to the garage ceiling, and installed Foilboard panels to the garage door. The results have been fantastic. Not only are our homeowners more comfortable, but they are starting to see a reduction in their energy bills!
