Garage Door Insulation: How to Insulate a Garage Door

Garage Door Insulation Process

Today’s homeowner knows the importance of energy savings, both for the environment and for their bank account. Without adequate garage door insulation, a lot of your energy and money could be going to waste and reducing the comfort in the rest of your home. Many homeowners overlook the garage as a source of energy loss because they spend so little time in it each day. Learning how to insulate garage doors yourself could save you hundreds over the cost of a new garage door if you really don’t need one.

Insulating a Garage Door

Studies show that insulated garage doors can keep the temperature in the garage around twelve degrees warmer during cold weather and around 25 degrees cooler in summer. That difference in temperature could have a big impact on how much your HVAC system runs year round. While the best option with older doors that aren’t in good condition is replacing them, newer doors that are in good working order are easily improved with the addition of insulation.

You have two options for getting the supplies you need. One is to purchase the materials separately online or from your local building supply company. The other is to purchase a kit that contains everything you need to insulate either a single or double garage door. Purchasing a kit makes the job even easier since it will contain the insulation for garage doors, fasteners or tape, and some high-end kits even include the gloves and a utility knife.

If you purchase the materials separately, you need to know which type of garage door insulation will work best for your garage door. Use foam board or reflective insulation for flat doors without panels and attach with glue or tape. For a wood frame or doors with panels, use rigid insulation and place into the recesses between the door frames.

Don’t stop at insulating the garage door. Add weatherproofing to the spaces where walls meet the floor and ceiling and put caulk around door and window facings. Better energy-efficiency comes from a comprehensive approach to stopping air flow in every area of the room.

Mount the Weather Stripping

Step 1: Start at the top of the garage door and tack the weather stripping to the top jamb. Continue in the same manner on the side doorstops. Pressing against the door will tell you how much movement to expect from strong winds. Readjust the doorstop to ensure it seals against the door in really windy conditions.

Once the weather stripping is in place, pound the nails in completely. If you are unable to eliminate the play in the doorstop or light still shines through the stripping, replace the hinges with spring-loaded ones that efficiently press the door against the weather stripping.

Step 2: Check the bottom of your door to see if there is a vinyl seal. Most doors have a bottom seal that cracks or breaks off after years of exposure to the elements. Open the crimps at the ends and slide the old seal out. Replace with a new seal to prevent cold air from entering at the bottom of the door.

Step 3: Lift the door halfway and let it go to see if it remains in place. The weight of the insulation may throw the door off balance. If the door falls, you need to call a professional garage door repair company to replace the springs or to readjust the tension in the existing springs. Leaving the garage door unbalanced can lead to damage and higher repair costs.
