If your garage is too cold in the winter and too hot in the summer, one problem that could be contributing to the discomfort is the lack of insulation in your garage door. Fortunately, you can insulate the garage door fairly easily. Here's how.
- Measuring tape
- Permanent marker
- Polystyrene foam board or reflective foil insulation
- Utility knife
- Double-sided tape
Purchase the Materials
Before you head out to buy what you need, measure the garage door. This will give you the square footage so that you can purchase enough insulation to get the job done without wasting money buying too much.
You'll have two main types of insulation to choose from:
- Polystyrene foam board (blue board) – Comes in 4x8 foot sheets. You want the 1.5" thick blue board for this project.
- Reflective foil insulation – Comes in rolls which makes it easier to haul if you don't have a truck.
Measure and Cut
Once you've purchased all of the materials and gathered the supplies, it's time to get working. Measure each panel of the garage door being very careful to measure accurately. Now, take those measurements and measure and cut the insulation.
Tip: To keep your cuts straight, lay a board across the insulation to use as a guide.
Hang the Insulation
Apply double-sided tape around the edges of the garage door panel. Add a few extra strips of the tape to the centers to give the insulation a little more support.
Position the insulation over the first panel of the garage door. Open and close the door to ensure that the insulation doesn't hang out and rub when the door is opened. Trim any overhang with the razor knife and move on to the next panel.
If you don't feel confident that the double-sided tape will maintain its hold, you can get some aluminum foil tape to trim the edges. This will not only help to keep the insulation in place but will also seal up the last little bit of gap to keep air from coming in around the insulation.
If your garage door is old, isn't really in the greatest shape or you just don't think that this fix is the solution for maintaining a comfortable temperature in your garage, talk with your local garage door expert about your options. You may be pleasantly surprised at the options that you'll be provided in new garage doors and the efficiency that they offer.
