Insulated garage doors help you save on cooling and heating costs. How do you know if the entrance to your garage needs insulation? Properly insulated entrances will not conduct the outside weather to the rest of your house.
Most homeowners do not realize that doors need insulation just as much as any other wall in the home. Garage doors are big, and if they are not well insulated, they can be a big waste of electricity.
If you have a garage that connects in any way to your home, through the kitchen, foyer, living room, or any of the bedrooms, you need to insulate it or you will feel the loss of heat and cooling in the connected areas.
In addition, if it is your main work area for handyman projects, woodwork, etc. then you had better get it insulated. Also, garage areas also make a large play area if you have children in your family. How nice it is to have a warm space for them to play when it is cold outside.
Metal is a fantastic conductor of both heat and cold. While metal doors are more troublesome than wooden garage doors when it comes to insulation, wooden ones also need to be insulated. When you feel a definite chill or heatwave when you walk out to get your car, despite the heating or cooling that you are pumping into the rest of the house, you need to insulate the entrance.
There are dozens of easy DIY insulation kits that you can use, but the time and effort it takes for you to figure it all out are not always worth it.
