For many of us, garages serve a purpose beyond simply storing and protecting our vehicles. They’re spaces where children play, dogs rest, and projects are tackled that would be too messy for indoors. However, if left uninsulated, garages can become cold and uncomfortable. While plug-in space heaters can warm a small area, they can also pose safety risks and lead to high costs over time. Moreover, portable heaters typically only provide about 20% of the heat needed to adequately warm a standard two-car garage.
