Insulating your garage door has a number of benefits. It allows you to cut your energy bills, reduce street noises, and helps protect the items stored in your garage from harsh outdoor temperatures. Thus, if your garage door has not been insulated yet, it is high time to fix it!

 

Below, you will find eight steps to help you deal with the garage door insulation process. They range from choosing the proper insulation to installing retainer pins to cutting the insulation to tucking it into the door panels, among other things. Read on and insulate your garage door efficiently!

Choose the Right Insulation

If you want to insulate your garage door, you will need to choose the right insulation first. One of the most popular options is to use fiberglass insulation. It is an excellent option due to its effectiveness and availability in a wide range of thicknesses and densities. Moreover, fiberglass is environmentally friendly and does not compress over time.

 

However, if you want to insulate your garage door, you can opt for the less popular but equally effective options, such as mineral wool and polystyrene. These materials protect well but are more expensive than fiberglass.

 

If you decide to have mineral wool or polystyrene installed by a professional, you will need to contract with a company specializing in garage door insulation, as these materials require special care and installation techniques. Most frequently, it is enough to Google “garage door parts near me” to find a service nearby.

Measure Your Door

When measuring your garage door, make sure you measure both the exterior and interior dimensions of the door. You will need the measurements to find out how much insulation you need. However, if you want to prevent lumps, it is best not to include the frame when taking measurements. Also, remember that you will have to take into account the thickness of the insulation as well when measuring your door.

Cut the Insulation to Size

If your garage door is not fully insulated yet, you will have to cut the insulation materials to size, so they fit properly. When cutting materials, it is best to use a sharp blade to avoid fraying. Also, make sure you cut slightly larger pieces than needed so that you can tuck them in safely later on. Keep in mind that you will have to cut several pieces of insulation depending on how many panels your garage door has.

Install Retainer Pins

Installing retainer pins is not a mandatory step. However, it can be quite helpful if you want to secure the insulation properly. By installing retainer pins, you will be able to prevent the insulation from slipping out of place. Also, some experts believe that by installing retainer pins, you will obtain better insulation results.

 

To install retainer pins, start by making a small hole in each panel of the door. Then, insert a retainer pin into the holes and secure them with nuts and washers.

Tuck the Insulation Into the Door Panels

Tucking the insulation into the door panels is not always an easy task. Therefore, make sure you are wearing protective clothing while you are carrying out this step. You should wear a pair of gloves, glasses, and earmuffs to prevent burns, scratches, and hearing damage.

 

To tuck the insulation into the door panels, start by placing a piece of insulation between the top and bottom panels. Then, trim the insulation slightly and tuck it into the crack between the panels. Carefully pull the insulation over the edges of the panels so that it appears even and does not have any lumps. Make sure you tuck the insulation in every panel of the door.

 

Repeat this process until all ends are properly tucked in. Remember that if your door panels have windows, you will need to cut small pieces of insulation and tuck them in behind these windows. This will help protect them from cold weather while also preventing drafts from coming inside your home.

Apply Caulk If Needed

If your garage door was not correctly installed and there are gaps between panels, or if you have recently experienced extreme temperature changes, you should probably apply caulking around them to prevent air leaks and drafts.

 

To do so, simply apply silicone caulk around each panel or window at the bottom and top of each crack or gap and smooth it even with your finger if necessary. Then allow it to dry for several hours before installing new insulation on top of it if needed.

Insulate the Garage Door Bottom

Depending on the quality of your garage door insulation and the number of panels, you may need to insulate the bottom of the door as well. To do so, remove the panels to expose the bottom of your garage door. Then, cut a piece of insulation that fits exactly beneath the door with a generous allowance for tucking it into place. Proceed to tuck in the ends of this piece just like you did with the top panel, and then replace the panels on top.

Test Your Garage Door Insulation

Once you have finished insulating your garage door, it is time to test it. In order to do so, close the garage door and wait for several hours. Then, open it again and check whether the panels feel cold to the touch and if any drafts are coming out of it. If there is no noticeable change in temperature, you have successfully insulated your garage door with fiberglass!

Final Note

Insulating your garage door is an essential DIY project that will not only save you money on your energy bills but also prevent drafts in your home and, therefore, make your life easier and more comfortable. I

 

If you are planning to do it yourself, be sure to follow the steps above precisely. Also, make sure to wear protective clothing and safety gear, such as glasses and gloves, while working on the project.

 

However, if you feel like the process is too complicated and you need help with insulating your garage door, or you face are any issues during the process, do not hesitate to contact a professional garage door company for assistance. Thus, you will avoid unnecessary expenses and reduce the risks of the insulating process itself.
