Hi. I’m Melissa Skinner with Great Day Improvements. Welcome to our Easy How-To Home Improvement Videos. Today, we’re going to insulate a garage door.

As with any home improvement project, having the right tools will save you time and money in the long run. For this project, we recommend getting the following items:

  • A garage door insulation kit – sold at most hardware stores for around sixty dollars. Keep in mind these kits are typically packaged with enough material to cover one door. If you have a double bay door, you’ll need two kits to complete the job.
  • A pencil
  • A tape measure
  • A utility knife or scissors
  • Work gloves
  • Safety goggles
  • A mask
  • And a ladder


One thing you need to keep in mind before you begin insulating is the increased door weight once the project is complete. Typically, when garage doors are installed, springs are calibrated to the door’s factory weight.  By adding insulation afterwards, you’re significantly increasing the door’s weight, which will wear out your springs much faster. I highly recommend having a professional garage door company re-weigh your garage door once the insulation installation is complete so they can recalibrate your garage door springs. This will save you stress and aggravation down the road.  

One final tip before we start: Pick a warm day to begin. If you wait until the weather is cold or icy, the installation pins won’t adhere properly to the door, especially if there’s condensation present. Plus, the plastic pins holding the insulation to the garage door have a greater likelihood of breaking in the cold. So, plan ahead!

Are you ready to insulate your garage door? Great. Let’s get started.

  1. Begin with your garage door in the down position.
  2. With a pencil, mark an X three-to-four inches from each corner of every door panel along with one in the middle of each panel.
  3. Included with the insulation kit I purchased were adhesive squares, plastic pins and discs. Remove the backing from one side of the adhesive square and press it firmly against the bottom of the pin.  Remove the backing from the other side and firmly press the pin to the garage door over-top one of your Xs. Repeat until there ‘s a pin on top of every X marked on your garage door.
  4. Using your tape measure, determine the length and width of your first garage door panel. For the most part, they should all be identical, but it’s always a good idea to double check.
  5. Put on your goggles, gloves and mask. If you have sensitive skin, you should probably wear a long-sleeve shirt and pants to protect the rest of your body. Remember, insulation is fiberglass and very irritating to the eyes, skin and lungs.
  6. Unroll the insulation.
  7. Cut your first section using the measurement of the door panel.
  8. Take the newly cut section to the appropriate door panel. The side with the vinyl coating should be facing out.
  9. Position the section of insulation so it lines up in the center of the panel.
  10. Apply pressure to the middle of the insulation until the middle pin pops through the coating.
  11. Immediately attach a locking disc to the pin by applying moderate pressure.
  12. Repeat for each of the four corners. Push the insulation against the door until the pin pops through the front. Apply locking discs to hold the insulation in place.
  13. Once the insulation is secured in the five locations of your panel, tuck in the edges of the insulation to the various lips and channels of your door. If you have a wood door, feel free to use staples and a staple gun to reinforce the edges.
  14. Repeat each of these steps until every panel of your garage door is covered.
