How Can You Improve the Energy Efficiency of Your Garage Door?
When energy bills start to creep up, homeowners often look to their HVAC system, but the culprit could be sitting in your garage. An uninsulated or poorly sealed garage door allows warmth to escape in winter and hot air to enter in summer. This causes your HVAC system to work harder to compensate, driving up your bills.
Luckily, you don’t have to live with an inefficient door. From sealing gaps to a full replacement, this guide offers seven ways to improve your garage door’s energy efficiency. Enjoy savings and a more comfortable home.
How Uninsulated Garage Doors Lose Energy
Before learning how to boost your garage door’s efficiency, it helps to understand common ways they lose energy:
- Conductive heat transfer: Uninsulated garage doors’ single-layer construction lets cold and heat pass through with minimal resistance
- Air infiltration: Single-layer doors are less durable and more susceptible to damage than insulated doors. Gaps in the sealing allow drafts into the garage or conditioned air to escape.
- Loss through adjacent spaces: In homes with attached garages, HVAC systems work harder to maintain temperatures in adjoining rooms.
- Limited temperature control: The lack of insulation means that the climate inside your garage depends on outdoor temperatures. An uninsulated door offers little protection against the weather.
7 Ways to Improve Garage Door Energy Efficiency
Boosting your garage door’s efficiency ranges from simple DIY fixes to professional upgrades. Here are seven steps to a more energy-efficient door:
1. Replace Weather Stripping
Weather stripping is a flexible seal installed around your garage door frame. It prevents drafts, water, dust and debris intrusion. Over time, the seal can become brittle or crack, reducing your door’s energy efficiency.
Follow these steps to replace or install weather stripping:
- Gather supplies: You need a tape measure, gloves, a utility knife and a screwdriver.
- Measure your garage door: Record the dimensions of the frame and cut the new weather stripping to size.
- Remove the old seal: You may have to loosen any screws before sliding the seal out of the track. Clean any debris from the channel.
- Install the weather stripping: Attach the new seal according to the manufacturer’s instructions. Slide it into the track or press the adhesive backing against the door frame.
- Test and adjust: Test the seal by closing the door and checking for light gaps. If you see gaps, adjust the seal or use some extra adhesive.
2. Seal Gaps Around the Door Frame
Even if your weather stripping is in good condition, there may still be spaces between the seal and door jambs. To check for gaps, close your garage door during the day and inspect it from inside. Look for daylight at the top, bottom and sides. Run your hand around the perimeter to feel for drafts coming through the door.
Should you discover any openings, use a silicone-based sealant and a caulking gun. Prepare the surface by cleaning it, then trim the tip of your sealant cartridge. Insert the cartridge into the caulking gun, position it against the gap in the door frame, and apply the sealant with consistent pressure. Allow it to cure as per the manufacturer’s instructions.
3. Insulate the Door, Ceiling and Walls
Consider insulating your entire garage if it connects to conditioned living spaces. It reduces energy loss, saves money, boosts comfort and even enhances indoor air quality.
A DIY garage insulation project includes:
- Garage door: Buy a DIY insulation kit for your existing uninsulated door. These kits often feature pre-cut foam designed to fit standard garage door panels. Follow the installation directions.
- Walls: Insulating walls involves filling stud cavities with an insulating material, like rockwool, fiberglass batt or rigid foam boards.
- Ceiling: Fit the appropriate insulation material between the ceiling joists. Ensure the insulation has a tight fit without any gaps.
4. Add a Threshold Seal
Unlike weather stripping, a threshold seal attaches to your garage floor instead of the door itself. It forms a complete barrier against water, pests and debris. Start by cleaning the concrete floor, then cut the seal to size, apply adhesive and press it into place behind the door tracks. Avoid driving over the seal while it cures.
5. Invest in a Smart Garage Door Opener
How often have you arrived at the office, only to realize you forgot to close the garage door? Besides creating a security risk, an open garage door wastes energy. Smart openers let you monitor and operate your door through a smartphone app. You can close your door from anywhere, saving energy and peace of mind. For example, LiftMaster myQ lets you get real-time alerts, set closure schedules, and close the door from anywhere using the myQ app.
6. Get Into the Habit of Regular Maintenance
Routine garage door care helps to maintain energy efficiency. A balanced, well-lubricated door closes all the way and maintains a tight seal.
You can perform these maintenance tasks yourself:
- Inspect the door: Perform a monthly inspection from inside the garage. Look for signs of wear or damage on the components and check for any gaps around the door.
- Lubricate moving parts: Apply a spray lubricant to hinges, springs and rollers twice a year.
- Test door balance: Check your door’s balance by disconnecting the opener and lifting the door halfway. It should stay in place. An imbalanced door struggles to close, which creates gaps that leak air.
Schedule a professional garage door tuneup once a year. idcAutomatic now offers a preventative maintenance program, idc Protect. Technicians examine your door from top to bottom, including the weather stripping. They tighten hardware, lubricate components and test functionality to ensure long-lasting performance.
7. Upgrade to an Energy-Efficient Garage Door
Replacing your existing, uninsulated garage door is the best way to improve energy efficiency. Modern doors feature advanced weather stripping, high-performance insulating materials and exceptional durability. Some models include thermal breaks. These insulating strips sit between metal frames to reduce heat transfer.
While a new garage door is a significant investment, it pays for itself through lower utility costs, fewer repairs and a longer lifespan. A garage door replacement offers an average return on investment (ROI) of up to 268%.
Energy Efficiency Considerations for Replacing Your Garage Door
If you’ve decided to upgrade to a new, energy-efficient garage door, pay attention to the following factors:
- R-value: Garage door R-value measures conductive heat flow resistance. Higher R-values mean better insulating performance.
- Solar heat gain coefficient (SHGC): How much solar radiation a garage door admits also contributes to energy efficiency. Homes in colder climates like Minnesota need doors with a high SHGC rating, which collect more solar heat in winter.
- U-factor: This rating measures non-solar heat transmittance. The lower the U-factor number, the more energy-efficient the door.
Polyurethane vs. Polystyrene Garage Door Insulation
You have two options when choosing an insulated garage door material:
- Polyurethane: Foam sprayed into the door cavity expands to fill every gap. It bonds to the door panels, adding strength and boosting moisture resistance. Polyurethane delivers higher R-values per inch than polystyrene.
- Polystyrene: Precut rigid panels fit between door sections. While cost-effective, polystyrene offers less thermal efficiency and lower R-values than polyurethane.
Choose polyurethane insulation for exceptional energy efficiency and durability. Opt for polystyrene if you’re on a budget or looking for a DIY upgrade.
Material and Glass Choices
Some materials provide better insulation than others. Insulated steel, aluminum or composite garage doors ensure thermal efficiency and durability. If your dream door has windows, choose double or triple-glazed options.
DIY vs. Professional Energy Efficiency Upgrades
Garage doors operate under heavy weight with many moving parts. Some improvements are safe to handle yourself, but others require expert help to protect you and your door:
The following are some tasks you may be able to handle on your own:
Weather stripping upgrades
Installing threshold seals
DIY insulation
Basic maintenance
These tasks require professional service:
- Garage door installation
Spring adjustment or replacement
Opener repairs
Structural repairs
Panel replacement
