One of the most cost-effective home improvements is also one of the most overlooked. If you’re like most homeowners, your garage door, and quite possibly, your garage is uninsulated. An uninsulated garage door not only increases your heating and cooling costs (“hello” high energy bills), but it can also be a welcoming sight for critters, and moisture. Both of which can be quite destructive. Insulating your garage door can provide unanticipated benefits thus making the project incredibly worthwhile.
- Climate control
- Reduced noise pollution
- Increased energy-efficiency
- Creates a stronger garage door
- Brightens what might otherwise be considered a dreary space.
At Banker Insulation, we’re committed to helping you through the process of insulating your garage door, by providing you with the following tips. These tips will ensure that you’re able to enjoy the many benefits an insulated garage door provides. Let’s get started, shall we?
#1. Types of Insulation Materials
Batt Insulation: Commonly made of fiberglass, batt insulation is more flexible than the other two options listed below, with insulation values between R-3 and R-4 per inch of thickness. Batt insulation is one of the more affordable options.
Foam Board Insulation: Typically made from polystyrene, foam board insulation is more rigid than batt insulation, but provides a much higher insulating value for relatively little thickness. R-values range from 3.3 to 6.5.
Reflective Insulation: Available in either rigid panels or rolls, reflective insulation reflects radiant heat, making it a viable choice for Arizona homeowners. R-values range from 3.5 to 6. Reflective insulation is one of the more expensive options.
What is an R-value? An R-value is the resistance of heat flow through a given thickness of material. The higher the R-value, the greater the resistance and in turn, your energy savings. An R-value, however, is just one of four key factors you should consider. Wind, humidity, and temperature are all factors that should also be taken into consideration when selecting an insulation material.
#2. Matching Insulation to Your Garage Door
- Steel garage doors can accommodate most any type of insulation.
- Wood frame and panel garage doors can accommodate either type of rigid insulation: foam board or reflective insulation. Consider applying two layers.
- Flat garage doors (those without panels) can accommodate foam board or reflective insulation.
You can purchase any type of insulation at your local home improvement store, for do-it-yourself installation, or contact an experienced insulation contractor for professional installation. If you choose to go the do-it-yourself route then you’ll need a tape measure, straight edge blade, and utility knife.
#3. Apply Weather Stripping
Before installing your chosen insulation, you should first apply weather stripping to the bottom edge of the garage door. With the door in the raised position, simply apply the adhesive side of the weather stripping to the bottom rubber gasket, to seal off the space between the bottom of the door and the floor of the garage.
We cannot reinforce the importance of measuring your garage door’s panels before shopping for insulation and again during the installation process. Whether you choose boards or rolls, cut the insulation to fit. You can attach insulation to the garage door using liquid nails or fasteners. Fasteners are available in kits.
