DIY- Easiest and Best Way to Insulate Your Garage Door Against Heat

Summer on the way means trying to keep the heat out of your home. For many people, the garage isn’t just a place to keep a car or use for storage, but it’s used as a room for different activities. It could be that you use your garage as a workshop, a home gym, or a place to work on your car. If you do, you know how your garage door is no barrier to the heat or cold.

If you interested in putting a barrier in place that will insulate your garage door against the heat (it also works somewhat when it’s cold by helping reduce heat loss) and help your garage be so much more comfortable, here is the best, the easiest, and the most effective way to do that. Also, if your garage connects directly to the house, this will help keep that heat out of your house.

You will need foam board with foil attached to one side. You can either purchase it or you may find that it’s cheaper to make it yourself. Instructions for making your own are at AtticFoil.

Supplies you will need:

  • 4 sheets of 8′ x 4′ foil-faced foam board (generally sufficient for a 2 car garage door)
  • Knife to cut the foam board
  • Measuring tape or yardstick

You can find the project with complete instructions at Instructables.
