Almost no one thinks about their garage when considering their home’s overall energy efficiency, and that’s a big mistake. You might be surprised to learn that your garage is actually the least efficient room of your house! Even though it might be several hundred square feet, garage rooms are almost never insulated, which means they can be sabotaging your energy bill.
Garage door maintenance is one of our specialties here at Lifetime Garage Doors and we’re always happy to come perform an inspection on your garage door system to see if there’s room for improvement.
Additionally, there are improvements that can be made to other elements of your garage that will help lower your home’s overall carbon footprint.
Insulate The Walls
Unless your home was built in the last couple of years, there’s a good chance that there’s absolutely no insulating material in the walls. This means your garage is basically a shed, allowing cool air to escape in the summer, and letting chilly air inside during the cooler winter months. Starting at around $1,000, you can correct this problem and greatly improve your home’s overall energy efficiency.
Caulk The Floor Seams
Not interested in investing all the money it takes to insulate your walls? You could still make a big difference by caulking the connection between the walls and your concrete floors, and it will only cost you a few dollars! Here’s how HowThingsWork.com explains it: “What happens is over time this connection swells, shrinks, and moves, leaving spaces which will allow air from the outside to leak in. You can either use a foam sealant or a latex/silicone based caulk to seal this often overlooked area.”
Seal The Entry Into Your House
Don’t want your leaky garage affecting the energy use of your home’s livable areas? Start by making a tighter seal around the door that allows you to pass from the garage into the house. For about $10, you can install weatherstripping around the entire door frame, making it hard for air to escape or enter when the door is shut.
Insulate The Garage Door Itself
Many homeowners are surprised to learn that garage door insulation is even possible, but it’s actually a great way to bolster this first line of defense against the elements. If you’re planning on new garage door installation, it’s best to just invest in a pre-insulated door. However, if you’ve already got a door in place, and your garage walls are insulated, a DIY garage door insulation kit can be purchased for several hundred dollars.
Insulate Outlets And Light Switches
The final step in optimizing the energy efficiency of your garage involves a very small detail that many homeowners overlook: insulation of electrical outlets and light switches. “Not only should you be concerned about the penetration of hot or cold garage air through the walls, but also the carbon monoxide which is present after a vehicle has either entered or left the garage. These fumes can find their way into the smallest spaces between the walls and then enter your home without you even knowing it,” explains HowThingsWork.com. Gaskets for fixing this problem only cost around $5 per outlet.
