Many garage doors are “Non-Insulated” and allow a great loss of heating and cooling if your garage is attached to your house.
Insulating the interior of the garage door is easy and provides a substantial cost savings on your energy bills. To see if your garage door does have insulation already installed, with the garage door in a fully closed position:

This is a very easy project which can be done in a few hours, Just follow the instructions and you will be impressed on the difference this project will make.
- Tape Measure
- Utility knife and extra blades
- Straight edge 3’ft – 4’ft long (A solid piece of wood with a straight edge or yard stick)
- Safety Glasses
- ¾” or 1” foil faced foam insulation (Measure garage door opening – Height x width = SF)
- Example – If your garage door opening is 7’ x 8’ it would require 56 Square Feet of insulation
- 1-2 rolls of 1-1/2” aluminum foil metal tape or duct tape – The metal tape is the best
How to install the insulation:
- Measure the opening as shown above (Example is 1’3 5/8” Tall x 3’9 ½” wide) * Note your measurements may vary depending on style and size of door
- Add 1” to the height of the opening (Example 1’3 5/8” +1” = 1’4 5.8”) This will allow the insulation to be held in place by the hinged frame rails
- Place the insulation board on a flat surface such as your drive way. Mark the measurements on the foil side of the insulation and gently cut the insulation board to the proper size
- Place the piece you cut into the lower hinge rail and then gently bend the insulation into the top hinge rail and release
- Complete the job by doing the same thing to each panel and installing the foil metal tape or duct tape around all 4 side of each panel your installed the insulation board in.
- CAUTION: Do not allow the tape to cover the joint in the hinge rail or interfere with the rollers on either side of the door.
- After complete open the garage door and make sure that nothing binds or comes into contact with other surfaces or moving parts
