There are several benefits to having an insulated garage door, particularly if you live in a climate where the temperature varies greatly from season, or if you are living in an area where your garage door faces to the east or to the west.
In Cold Weather
- The garage itself can become very cold, compared to the rest of the house.
- The garage will not act as a buffer to keep the cold air out of the rest of the house.
- The cold temperature inside the garage is hard on your car battery. Definitely warm up the car before driving, or you could cause damage to your car overtime.
In Hot Weather
- The garage itself can become very hot, compared to the rest of the house.
- The garage will not act as a buffer to keep the hot air out of the rest of the house.
- An non-insulated east facing garage door can heat the garage to 100°F and higher every morning in the summer, heating the house, making your cooling system work harder and consume more energy.
- If you have a freezer in the garage, it will also work harder and consume more electricity as the temperature continues to rise.
Insulating a Door After the Fact
If you recently purchased a non-insulated garage door, or you moved into a home that has one but don’t want to upgrade your door yet, you can still insulate.
Next time you’re on the market for a garage door, look for a door that has a thick layer of insulation (high R-Value) between pieces of metal.
