Many homeowners today are skeptical about insulating their garage due to the perception that the garage space condition does not directly affect the in-house living conditions. Garage space should, however, be kept in good conditions, especially when you have a room right above it. Apart from the attic, the garage area is one of the places that are most prone to shifts in air conditions due to the infiltration of unwanted air.
If you have a room above the garage, and there are air leaks, it could lead to unbearable conditions in the room, ultimately leading to a rise in energy bills in an attempt to curb the adverse conditions. Other insulation methods can only effectively work for so long, but spray foam insulation is a guarantee of a nice balance of the natural air conditions in your room.
