Detached garages provide more versatility than just storing our cars.
We can use them as workstations or places for band practices. Cold weather is one of the few reasons why you wouldn’t want to set foot in your garage.
There are different ways you can keep your detached garage warm. Cold weather doesn’t have to be the reason why you don’t enter your garage.
I will explain here the best ways to heat a detached garage, so you can use the one that suits you best to enjoy it!
Things we can Do to prevent losing heat
Insulation is one of the best methods to keep your detached garage warm. There are some affordable materials you can use to insulate your garage.
Spray foam is a chemical made with isocyanate and polyol resin. When the two are mixed together, the spray foam expands 30-60 times its liquid volume.
There are two types of spray foam:
- Medium density closed cell spray foam. This is often referred to as 2 lb. foam. The long-term thermal resistance R-value ranges between 5.1”-6’’
- Light density open cell spray foam has an R-value that varies but is commonly found to be around 3.8”. It has a sponge like appearance and it expands during application
The R-value is generally high compared to other insulation methods. Spray foam, therefore, has a high thermal resistance property and three forms of heat transfer:
Fiberglass roll insulation:
Fiberglass matts arrive in rolls or long strips called batts. The heat resistant R-value is 3.7” based on an R 13 insulation. Fiberglass can be installed in the garage’s walls and ceiling.
The fiberglass catches air between the layers to prevent heat from penetrating through into the garage. The insulation is great all year as it keeps heat in the garage during winter and out in summer.
Foam boards :
Foam boards are rigid panels of insulation which can be used to insulate all sides of the detached garage. They provide a good form of thermal resistance and reduce heat conduction through their structural elements such as wood & steel studs. The R-value ranges from 4-6.5” of thickness.
Windows and doors:
Cold air doesn’t only penetrate through the walls. One window is sufficient for cold air to penetrate through. Make sure your windows and doors are insulated too.
Insulating windows is easy and you don’t need any special materials. There are four effective window insulation methods you can install yourself.
