A tuck-under garage is a garage with living space above it. It’s typically seen in homes that are built on an incline.
We see a lot of these in our work because they were often incorporated into homes built in the 60s and 70s — homes that are often very inefficient anyway and may already have serious comfort problems and high energy bills. Rarely is there an air barrier between the garage ceiling and the living space above meaning that air can travel freely (and through fiberglass insulation) into the living space above.
Especially in these cold winter months, many homeowners start their cars in the garage and let them run for a few minutes to warm them up. Even in summer months when cars aren’t left running, the noxious fumes of the cars can easily float up into the room above. For some reason, the majority of the rooms above the garage tend to be a child’s bedroom which is now a very serious safety issue. Not only can carbon monoxide enter the living space on a daily basis, but if there isn’t a proper firewall (which we also find often) then a fire can spread easily to the room above. And garages are the most likely place in the home for a fire to start. (continue reading…)
