Upgrade Your Garage Door with Insulation to Maintain Energy Efficiency in Your Home

Heating or cooling your home is expensive, but little tricks can go a long way to lowering your electric bill. But one area of the house that’s often overlooked is your garage. Simply put, if your garage is connected to your home, you run the risk of losing heat or cold air much faster. Part of this can be attributed to frequently opening your garage door. However, another factor you may need to investigate is the insulation in your garage. Even if the walls of your garage are insulated, a garage door that is not insulated will still allow a large amount of heat and cold into your home. Often, the garage doors home builders install only come equipped with the bare essentials. If you want to achieve energy efficiency in your home, installing proper garage door insulation can be a great step in the right direction.

How Insulation Works

If a house is properly insulated, it can retain warmth in the winter and stay cool in the summer. Heat is always trying to migrate to colder areas. In the winter, insulation keeps the heat from leaving your house; in the summer, it keeps the heat from entering your home. Similar to the filling in a coat, its purpose is to provide a resistance barrier to the flow of heat. If you live on a noisy street, it may benefit you to know that insulation also comes with the added perk of creating an extra sound barrier.

Consider Your Options

Taking steps toward energy efficiency can have large up-front expenses, but they will save you in the long run.  Insulation costs for your garage door can range between $50 to over $1,000. If you have made the choice to install garage door insulation, the next step is choosing which kind is right for your home. When choosing insulation for your garage door, be mindful of its heat resistance, or R-flow. The higher its R-flow, the better your house will be insulated. You also need to consider the climate in which you live, as the requirements will vary according to temperature.

The first option to consider is polyurethane insulation. This is a foam material that is injected in between the two layers of your garage door. It forms a bond to both layers, filling 100 percent of the space and providing R-values between 2.0-18.0. It has the added benefit of creating a stronger, more durable door.

The second option is a polystyrene insulation. This rigid block of insulation is also placed in between the two layers of a garage door; however it is not attached like polyurethane. This option is more cost friendly than polyurethane, but also provides half the R-value.

Third, you can consider installing a radiant barrier. These rolls of insulation are fairly easy to install and cost-friendly.  Unlike the previous two options, a radiant barrier can be applied to the back of your garage door, rather than in between, making it a simple do-it-yourself project. The rolls can be easily adhered with double-sided tape, Velcro, or many other types of adhesive.

Lastly, you may opt for a completely new garage door. Installing a new garage door that is energy efficient may cost big bucks up front, but it can reduce the energy lost through your garage by up to 71 percent.

Seal the Deal

If you have taken the time, effort, and capital to install garage door insulation and make your home more energy efficient, there is just one more thing you should consider for optimum performance. Insulation doesn’t mean much if your garage door isn’t properly sealed. Check the weather seal around the perimeter of your garage door to make sure it is sufficiently blocking out the weather and air flow. Check the weather stripping and confirm that the gaps between your garage panels are sealed completely when the door is closed.
