How Do I Insulate My Garage Door to Keep the Heat Out?

No matter how properly you set up the garage door, it will undoubtedly leave a small gap in the bottom. It is something that the garage door manufacturers do intentionally because if the door goes all the way to the floor, the lower part will get scratched up or damaged.

That gap, however, lets the dust, debris, and other environmental elements get inside the garage. Most importantly, the gap can allow the heat from the outside to get inside. So, an insulation material is essential.

Park the Car Outside for a While

After driving for a long time, all of the car's components become exceptionally hot. If you park it directly inside the garage, the parts will release the heat to the interior. As a result, the environment will become hot.

Park the Car Outside for a While

So, instead of parking the car inside, we recommend you park it outside for a while. Keep it under a shade and let the components cool down a bit. Once the car cools down, park it inside the garage.

Ventilation

Open the windows of the garage during the day. It will let fresh air get inside and allow the air to circulate from the inside to the outside. This circulation will help keep the environment inside the garage cool.

Ventilation

Likewise, you could leave the garage door open for a couple of hours. However, this is only recommended when you are staying indoors. If you leave the garage door unattended, burglars and intruders can get inside the home and steal any of your price possessions.

Install a Ceiling Fan

Most of the garages do not have any windows. For those, we would highly recommend installing a ceiling fan. However, do not get indoor fans. Instead, opt for industrial-grade fans. Those will have strong blades, and they will be capable of withstanding the debris and dust in the air.

On that note, you can even get yourself a portable air conditioner. But if you plan to get one of those, do ensure that the size and power of the air conditioner are adequate to cool down the entire space.

How Can I Insulate My Garage Cheaply?

You do not have to spend too much cash in terms of installing the insulation material to your garage door. Most importantly, you can avoid the labor cost by doing it by yourself. Yes, it is certainly possible to install the insulation material by yourself! Do not believe us? See how simple the process is:

How Can I Insulate My Garage Cheaply

Step 1: Shop for the Materials

There are two types of garage door insulation kits available in the market. You can either shop for the vinyl-faced fiberglass kit or get the precut polyester panel foams.

The first one will provide a huge value proposition because you will get all the necessary materials for insulating an 8 feet wide door. However, you would need to cut the insulating materials by yourself. The second one comes in a precut form, but it will cost more than the non precut option.

Choose one that goes with your budget and planning and move to the next steps.

Step 2: Measure and Mark a Spot for the Retainer Pins

Next, you would need to mark a spot 12 inches away from each of the edges of the panel. Basically, this marking will be in the midway from the horizontal rails. Use a pen or a pencil to mark the spot and install the retainer pin base to the area. You would need to install two retainer pins for this project.

Lock the Batting in Place

Step 3: Cut the Batting

After marking the spot, you would need to roll out the batting. Keep the viny side down and mark the cutting lines. Keep scrap plywood under the batting, compress the insulation using a straightedge, and then use a utility knife to cut the lines.

Step 4: Lock the Batting in Place

Once the batting is prepared, you need to line it up so that it is centered with the panel. Use gentle force to push it against the retainer pins. The pins will puncture the vinyl side of the insulation. You would need to push the retainer cap over the pin. It should snap right into place.

Step 5: Prepare the Bottom of the Door

At this point, the retainer cap should be ready, and you would need to wash the panel using rags and cleaning sprays. Make sure to rinse the areas properly with clean water. Allow the area to dry up before installing the retainer pins.

Prepare the Bottom of the Door

Do make sure that the measurement and the dimension of the cuts are right before moving any further. If everything seems right, push the cuts into place and secure them by using the retainer pins. Repeat the process for all of the panels of the door.

Step 6: Make the Door Ready for Weather Stripping

After the batting cuts are in place, you must place the doorstop against the side jambs and the top. The vinyl weather stripping needs to make a 45 degrees angle. So, you can place it temporarily and check whether the angle is correct or not.

Step 7: Adjust the Door

You would need to simulate the effect of a strong wind in this step. Simply apply pressure to the door, and make it move a little. It should move inward, but the weatherstripping should make a proper seal, eliminating the gaps and not letting the air get inside.

Step 8: Uncrimp the Bottom Slots

In this step, you would need to gently bend the track out a little. Simply put a fat-blade screwdriver into the crimped area. Twist it gently and let the aluminum track expand a little. Repeat the process one the entire track and on each of the ends.

Step 9: Clean the Bottom Slot and Install the Strip

Next, you need to clean the slot and ensure no dust or debris can build up inside it. Make a cleaning solution using dishwashing detergent and clean the slot with a brush. Let the slot dry up, and then spray some silicone spray on the area.

After that, install the vinyl seal and drag it along the entire slot. Cut off any of the excess seals on edge afterward. You also need to use a pair of pliers and a utility knife to crimp the ends of the tracks. This crimping will help the track to retain the seal in place. As a result, the seal will achieve a longer lifespan.

Uncrimp the Bottom Slots

Once everything is in place, you need to test out the door. Open up the door and let it close fully. The seal should squish in place, and the inside should maintain perfect insulation once the door closes.

Final Words

To conclude, we hope you found the proper answer to how do I insulate my garage door to keep the heat out. All you need to do is install a proper insulating material, place a strip on the bottom, and ensure proper ventilation inside the garage.
