DIY Garage Door Insulation keeps your garage cool in the summer and warm in the winter.
What is the best garage door insulation? If you live in the southern or southwest US, chances are you have experienced how much heat can build up in your garage. The source of this heat buildup may be your garage door. Your uninsulated or underinsulated overhead garage door allows radiant heat waves to penetrate through it, trapping excess heat in your garage. EcoFoil insulation uses reflective foil bubble insulation to block the transfer of radiant heat energy through your garage door.

Garage Door Insulation DIYThe garage is usually reserved for storage and those projects too dirty for inside, which is why it is commonly overlooked when it comes to insulation. It is easily the largest un-insulated area of the home. When insulated properly, an attached garage can serve as a buffer between the home and the ambient cold or heat outside. It is not sufficient to only insulate the walls and ceiling. One overlooked element is the garage door. For example an 8’x16’ garage door would leave 128 square feet of un-insulated space, which is very significant.
By insulating your garage door you will stabilize the temperature of your garage during all seasons, which will in turn stabilize the climate inside your home. There are many benefits to garage door insulation, one of which is creating an environment that protects your vehicles from the harsh effects of extreme temperatures. During the winter months your batteries will last longer due to easier starting, oil will retain its viscosity, and gas lines will be less likely to freeze. An insulated garage will also keep your car cool in the summertime.
Insulating your garage door is a relatively simple project that can be done in one weekend using common tools that are found in most toolboxes. There are many garage door insulation kits on the market. There are four basic methods for insulating a garage door:
1. Spray Foam garage Door Insulation. Spray foam is installed by fitting a panel inside the door channel. Foam is then sprayed in the space between the door and the panel. This is the most effective method because when the foam expands and hardens it fills all of the gaps. Also called insulfoam garage door insulation, this method is the most expensive and the least approachable method for the average consumer. It is best to leave this method to a professional.
2. Rigid Foam Insulation for Garage Door: Rigid foam requires no glue or adhesives to install because it is cut to fit, and wedged into place. It is best to use foam that is faced with foil or laminated plastic for durability and appearance. This method is not recommended due to the potential fire hazard exposed polystyrene presents.
3. Fiberglass Garage Door Insulator: Fiberglass insulation can be installed using various adhesives depending on the particular brand of items. Double sided tape and other fasteners are some common methods. Fiberglass should be faced with vinyl for protection and aesthetics. The drawback to fiberglass is that it is hazardous to work with, has a bulky appearance, and has the potential to be easily damaged.
4. Radiant Foil Garage Door Radiant Barrier: Radiant foil, such as EcoFoil’s double bubble reflective foil garage door insulation is installed using heavy duty double sided tape. This is a safer alternative to fiberglass, and more compact solution than rigid foam. In addition to providing significant R value, EcoFoil’s radiant foil reflects 96% of radiant heat, serves as an excellent garage door vapor barrier, and has a Class 1 Class A fire rating (ASTM E84-09).
