How to Insulate a Garage Door
Insulating your garage door comes with a whole lot of benefits.
The highest benefit of having an insulated garage door is that it saves energy.
Garage doors that are insulated are more durable than uninsulated doors.
Besides, your car will also be protected from bad weather that could prevent it from running properly.
To those who use their garage as a workout area, insulation can make the space more comfortable and bearable.
You can replace your garage door with an insulated one at an affordable price.
If that would be too costly for you, then you can use the DIY tips below to insulate your garage door.
Get the right materials
Before you order for the necessary materials, you must do research and come up with the ones with a high R-value.
R-value is a rating given to materials that offer effective insulation.
The right materials will be determined by the method of insulation you choose.
Basic insulation materials include;
Reflective foil insulation
A reflective foil is a thick material about an inch and a half and usually sold in rolls.
This type of method is quick to install, easy to clean, and soundproof. First, measure the garage door panels.
After measuring, cut the reflective material to the right dimensions.
Then attach the foil on the door panels using an adhesive spray, staple gun, and screws.
For safety reasons, you will need to protect your eyes when using a staple gun.
You should look out for any worn-out wiring and fix them first for your personal security.
The batt insulation
This type of insulation is made of fiberglass.
It would be best if you protect yourself before using this method because fiberglass is irritating to the skin and throat.
First, roll out the batting.
Clean the door panels and allow them to dry.
Then Measure the door panels and cut the batt for a tight-fitting.
The fitting must be snug to prevent any heat loss. After the measurements and cutting, fit the insulation.
Ensure the side with vinyl faces the inner side of the garage.
Insulate all the panels and use pins to hold the insulation in place.
It is advisable to test the door immediately after the installation process.
In case you find that it is imbalanced due to the weight of the insulation material, try reaching out to a professional who will handle the correction for you.
Rigid foam insulation is another easy way to insulate your garage door.
Measure the door panels with a measuring tape.
Then, measure and cut the insulation foam according to the measurements of the panels.
Apply a good amount of construction adhesive on the cut insulation foams.
Afterward, fit the insulation foams on the door and press down to bond the garage door with the insulation.
Again the insulation foam should be a snug fit to keep the outside air from penetrating.
You should wait for a couple of hours for it to dry so you can use your garage.
The spaces between the panels should be covered with an aluminum foil tape.
With this method of insulation, there are three types of foam insulation boards you can use — Polyisocyanurate, polyurethane, and polystyrene.
Among the three, polystyrene is the cheapest type of insulation with a low R-value of 4.
The other two have an R-value of 8, making them better insulating materials.
What you need to know before insulating a garage door.
Before installation, consult the building authorities to advise on the code requirements.
The authorities will help you choose the right method to insulate your garage door.
In case of a fire break out, rigid foams give out toxic fumes though they are not highly flammable.
Choose an insulation method that will be easy to install.
Note, if other areas in the garage are not insulated, insulating the garage door will not be of much value.
Apart from the garage door, the ceiling, floor, and walls are also sources of heat loss.
Insulating all of them will help you save a couple of dollars on your electricity bill.
Whether your garage is separate or attached to the house, you want to use the least energy possible.
