DIY Garage Door Knee Wall Insulation

Neighborhood Garage Door Services of Toledo, Ohio is an industry leader when it comes to garage door installations, repairs and regular maintenance. We’ve served the Toledo area for over 20 years and take great pride in both servicing our customers and giving them helpful tips and advice.

There are so many things you can do to improve your garage door or use it to the fullest potential. We like to share ideas to help you get the most of your overhead door. For example, you can add insulation as a DIY project from home.  We even encourage customers to try to insulate the knee walls in their garage door.

Knee Wall Insulation


Knee walls are typically found in attics and upstairs living quarters. They are low walls that are formed by the sloping of rafters and a finished floor. Builders often frame them with 2x4s and they reach about 4 feet high.

People don’t realize that quite a bit of heat can escape from knee walls. They leak heat in two ways. Knee walls lose the warmth through the wall and the via the floor joist. You can save money if you keep your garage and home better insulated.

How to Add Garage Knee Wall Insulation

If you’ve decided to take the plunge and add insulation to your garage knee wall, then good for you! Our team always encourages customers to do this and believes you won’t regret the decision to add insulation.

This is a project that can be done at home on your own, but if you need our help, then be sure to give us a call. We’d be happy to walk you through the process.

Faced or Unfaced Batts

There are a few things that you need to consider in advance. For example, are you planning to use faced batts or unfaced batts? We will walk you through both options for your convenience.

Faced Batts

If you are going with faced batts, then place them into the wall cavity and use a stapler to attach the flanges of the batts to  the inside of the studs approximately every 12 inches.

Unfaced Batts

Customers that use unfaced batts should place their insulation into the cavity where it fits nice and snug at the edges and ends. You will want to be sure it doesn’t stick out the back in any way. The correct size is important in this step.

Insulation Size

Be sure to cut your insulation so that it fits properly. The project will go much more smoothly if you pay close attention to this step. Cut the insulation to the correct measurement and don’t compress it. A sharp knife and straightedge will do the trick.

Use a smooth surface to cut the batts and cut them to a size of about one inch larger than the wall cavity. If you are a little off, then just fill the gap that was created with an extra piece.

Air Leaks

If you have spots that gape a bit then place pieces of unfaced insulation into the gaps with a screwdriver. In order to prevent air leaking, you should try and use caulk or some other sealant around the areas that appear open.

In order to complete your knee wall insulation project, you’ll want to double check the insulation. Be sure that you have ensured there are no gaps where air can leak out.

They sent Doug Fussell out to my house on the day after Christmas! I had only called them three days before! Doug was a premier technician, very thorough and very efficient. I expected him to take two days, since he was replacing two doors and adding openers on each door. He only took the daylight hours of one day! I could not believe how fast he was! In addition, he thoroughly taught me how to use the remote openers. I highly recommend them to anyone!

We just bought a home and this company was so understanding as I had to change the appointment time a few times. Then the tech came out and was so kind and helpful. I could not have asked for a better experience and will suggest them to anyone who needs work done on their garage door!

My garage door broke on a Saturday night as I was getting ready to leave for a holiday party. Kelvin was here within 30 minutes. He reviewed everything with me that was happening with my door. He gave me the estimates of what was immediately needed to be done in order for my door to raise and then what I will need to have done very soon. I could see all the problems he pointed out to me and I decided to have everything done. He completed everything that night. I was very satisfied with Kelvin’s professionalism and the work he did. Thank you again.
