How To Improve the Energy Efficiency of Your Garage Door
You can improve your garage door’s energy efficiency by adding insulation, sealing gaps and making smart choices about windows.
The most impactful upgrade Central Oregon homeowners can make is switching to an insulated door. R-values 0 to 20+ rate doors on how well they stop heat from flowing out of your garage. R-9 to R-12 doors are thicker with rigid foam or polyurethane spray foam injected between steel skins. They perform well in attached garages and residential settings. But keep in mind, a high R-value door won’t help if your garage walls, ceiling and windows are uninsulated.
To improve the energy efficiency of your garage door, replace worn weatherstripping along the sides, top and bottom of the frame and swap out a cracked bottom seal. If your garage door has windows, you’ll want to pay attention to the glass. Single-pane glass loses heat faster than a solid panel, so ask about double-pane or insulated glass options. That way, you keep the natural light and curb appeal without giving up much warmth.
The Hidden Cost of an Uninsulated Garage Door
Your garage door is probably the biggest mechanical moving part in your home. If it’s hollow or aging, heat slips out through the door, around worn weatherstripping and under a cracked bottom seal. When your garage feels colder than the rest of the house, or your heating bill spikes without a clear reason, your garage door is probably the culprit. For families in locations that experience cold temperatures and lots of snow, like Bend, Redmond, Sisters and La Pine, that heat loss adds up fast.
Frequently Asked Questions
Here is some additional information to help you improve the energy efficiency of your garage door.
Does Insulating Your Garage Door Actually Help?
Yes, it does. An insulated door reduces heat loss through the door itself — often the biggest source of energy loss in a garage. If your garage is attached to your home, the rooms beside it will feel warmer. You can think of it as one of the higher-impact upgrades you can make for your home’s comfort and efficiency.
How Do You Actually Benefit From an Energy-Efficient Garage Door?
An insulated garage door makes a measurable difference in comfort — and your garage is quieter and more usable year-round. You also get a door that feels sturdier and tends to last longer, which means better long-term value on top of day-to-day savings.
Does Opening a Garage Door Use a Lot of Electricity?
Not really. The wattage a garage door uses depends on the motor type, door weight and how often it’s used. Running a garage door opener doesn’t cost much over the course of a year. The bigger drain is heat escaping through a poorly insulated or unsealed door.
