5 Ways to Weather-Seal a Garage Door

5 Ways to Weather-Seal a Garage Door


5 ways to weather seal a garage door

Sealing your garage door against the weather helps protect the space and keeps your belongings safe. Learn how to seal garage doors and weatherproof your garage with these five tips.

1. Bottom Weatherstripping

Also known as a door sweep, bottom weatherstripping is a common way to seal a garage door. This rubber seal attaches to the bottom of your garage door and compresses to fill gaps between the door and the floor. Garage door weatherstripping is available in rolls from most home improvement stores.

Bottom-seal weatherstripping generally comes in a standard shape that fits in the channels on the bottoms of most garage doors. If you have a wooden garage door, you may need to screw or nail in the weatherstripping. Be sure to choose aluminum or galvanized fasteners to prevent rusting. You can also install a metal channel to make your wood door compatible with standard seals.

Replacing bottom weatherstripping is relatively easy. First, remove the old seal. Most kinds pull out of the channels on the bottom of the door. However, some seals may have screws or nails, even on metal or fiberglass doors. Once you’ve removed the old seal, clean the bottom of the door. Push the new seal into the channels in one continuous piece, and trim it to fit your door. If the old weatherstripping had nails or screws, replace these fasteners as appropriate.

2. Threshold Seal

A threshold seal also fills gaps between the door and the floor, but this garage door seal attaches to the floor instead of the door. It can stand alone, but is more effective when combined with a bottom seal. Since it’s durable enough to drive over, a threshold seal typically consists of harder rubber and is longer-lasting than weatherstripping.

This seal can help keep water out of your garage if the driveway slopes toward the garage, but it can also make it more challenging to hose out or sweep your garage. It can also be a good option if your door meets the ground asymmetrically. However, if your door is significantly irregular or suddenly becomes uneven, it’s best to call a professional to repair and adjust it.

To install a threshold seal, mark the floor where you want it to be with chalk or a permanent marker. Clean the floor and wipe down the bottom of the seal. Apply construction adhesive to the floor in two lines along the edges of the seal and in a zigzag down the middle. Place the seal and gently press it into the adhesive. Most adhesives need 24 hours to cure before you can drive over them.

3. Top and Side Weatherstripping

Rubber weatherstripping is also available in a slightly different configuration for the tops and sides of the door. However, this seal attaches to the door frame rather than the door. Garage weatherstripping is available in rolls at most home improvement stores and cuts easily with a utility knife. It should sit flush against the trim, so you may need to remove raised strips from the frame or sand it for a smooth finish.

Measure and cut three pieces — one for the top and one for each side. Cut the ends of the top piece at an angle to accommodate the side pieces. Attach the weatherstripping with aluminum or galvanized nails or screws to avoid rust. Install the side pieces first, then the top overlapping the side pieces. The outside flange should touch the door along the top and sides when the door is closed. Caulk where the seal meets the frame. Be sure to use a caulk for garage doors or exteriors.


4. Brush Seals

Rather than being solid rubber, these seals use brushes, which are more flexible and durable than standard weatherstripping. Brush seals are more common along the top frame, but you can also install them on the sides. They cover the gap created when the door bends into the garage. Because brush seals aren’t a solid barrier, air, debris and small bugs may still get through. These come in multiple pieces and secure with adhesive tape. The brush should touch the door when it’s closed to be most effective.

Once you’re ready to install, clean the frame for better adhesion. On the first piece, pull the brush out of the track and cut it about 2 inches short. Attach adhesive tape to the track and press it onto the frame. After attaching the second piece, feed the brush from that piece into the track on the first piece. This overlap helps ensure no gaps between pieces. To account for this overlap on the last piece, pull the brush out 2 inches before cutting the track to fit with a hacksaw.

5. V-Type Seals Between Panels

This product seals gaps between garage door panels for enhanced weatherproofing. Many newer doors won’t need V-type seals since their panels have interlocking edges to block air when the door is closed. These seals are best for older or wooden doors with flat panel edges. Be sure to count the number of panels in addition to measuring the door’s width. Because V-seals cover moving parts, they can wear out faster than other weatherstripping types. It’s best to check them every three months.

To install V-seals, clean the inside of the panels where the seals will stick. Cut the seals to fit between the panels in one continuous piece. Pull back part of the adhesive backing, but don’t remove all of it at once. Fit the seal between two panels and press firmly into place. Continue peeling off the backing and placing the seal as you move along the door.

Frequently Asked Questions

If you aren’t sure whether sealing your garage is worth it or have more questions about replacing weatherstripping, you can find the answers to frequently asked questions here.

Why Should I Weatherproof My Garage?

Weatherproofing and weatherstripping are essential for keeping out water, debris, bugs and other pests, which can get into your home if you have an attached garage. Other benefits of weatherproofing your garage include reduced cleaning and improved energy efficiency. If you heat or cool the space, weatherproofing can help save you money on energy use.

How Do I Know if I Need Weatherproofing?

If you don’t currently have weatherproofing, you could likely benefit from adding some. Garage door weatherproofing provides several advantages and is relatively easy to do. To determine where you need weatherproofing, stand in your garage with the door closed and the lights off. If you see light coming in around the garage door, you want to seal those gaps.

How Long Should Garage Door Weatherstripping Last?

Weatherstripping lasts two to three years, but it’s best to check annually to see if it needs replacing. Weatherstripping may wear out faster on doors that experience heavy use.

How Do I Know When to Replace the Weatherstripping?

Good weatherstripping is pliable and soft to conform to the door’s shape and compress into any gaps. It’s time to replace your weatherstripping if it’s hard and brittle. You also need new weatherstripping if you notice cracks, tears or rips. Even if the weatherstripping seems to be in good condition, it might need replacing if you feel a draft, see light around the door or find more dirt near the frame.

Can I Install Weatherstripping Myself?

Yes! Adding or replacing weatherstripping is a manageable do-it-yourself task for most homeowners. Caulking and other weatherproofing methods are also suitable for DIY.

However, you can also hire a professional if you don’t feel confident in your skills, need other garage door repairs or don’t have time to do it yourself. AAA Garage Door can install, repair and replace your weatherstripping.

How to Keep Your Garage Cool in Summer

How to Keep Your Garage Cool in Summer

Just like keeping your garage warm during the frigid winter months, maintaining a cool garage space during the summer season is more than ideal — especially if you live somewhere prone to cold winters and hot summers. 

If your garage serves as a multipurpose space for work, hobbies or projects, high temperatures can cause excess sweating and discomfort, inevitably tiring you out more quickly. Luckily, we have plenty of tips for cooling down your space. Learn how to keep a garage cool in the summer with this handy guide!

6 of the Best Ways to Keep a Garage Cool

Making some slight adjustments to your garage for summer can help improve air circulation and better organize your space. Just like cold weather can affect garage door openers, sunlight and heat can also compromise their effectiveness. High temperatures can interfere with the operator motor’s sensors and wiring. 

Fortunately, insulating your garage door and practicing the other tips below can help keep warm temperatures at bay and protect these sensitive components from heat. Let’s dive in!

1. Install a Fan

Having a fan in your garage can make a world of difference. It can improve ventilation, make the space less stuffy and help push hot air out of the garage. The strong airflow from a fan can increase cooling significantly, boosting the rate of evaporation from your body. Keep in mind, however, that a fan typically works best with moderately warm temperatures. It may be ineffective if your garage is sweltering hot.

You should also note the dimensions of your garage if you’re thinking of installing a ceiling fan. If your garage ceiling is lower, a ceiling fan could interfere with your garage door opening or closing or prevent you from parking a larger vehicle in the space. The ceiling fan’s blades should be 7 to 9 feet above the floor, as well as 10 to 12 inches below the ceiling.

2. Declutter Your Space

Believe it or not, a garage full of clutter can raise the temperature in your space. Stacked boxes, bulky tools and machinery on the floor not only take up lots of space but can also block airflow, creating a hotter, more stagnant space.

An afternoon of decluttering your garage can help improve your space’s airflow and organization and make it easier to park your vehicle, of course. Installing shelves, cabinets or storage racks — if you don’t already have them — is a great way to maintain a clutter-free garage and keep the temperature in check. Remember to tidy up regularly, returning tools and boxes to their places after each use.

Invest in an Air Conditioner

3. Invest in an Air Conditioner

Arguably the most obvious yet expensive solution, installing an air conditioner in your garage is a surefire way to cool down your space. You’ll want to invest in a separate unit for your garage space, like a ductless wall-mounted mini-split or window air conditioner. 

Consider a through-the-wall air conditioner if your garage has no windows. This would involve carving out a rectangular section in the wall to fit in the air conditioner. It’s quiet, highly efficient and can cool a space in just minutes. 

A mini-split works just fine without windows as well — all you’ll need is a small hole high on the wall, and you’re good to go. The main drawback of a mini-split is the additional energy expense, but using a smart AC controller can help cut down electric bill costs.

You should only opt for one of these options if you spend a considerable amount of time in the garage — that way, it’s more worth the expense. 

4. Opt for a Lighter Wall Color

You may have been told at some point that wearing dark-colored clothing in the summer makes you hotter. Likewise, the darker your garage walls are painted, the more they absorb heat. 

Try a lighter-colored paint such as white. We recommend taking up this project before the summer season arrives — preferably in spring — and you may notice your garage dropping a few degrees. It may not be the most glamorous solution, but it sure can make an impact. 

5. Improve Insulation

Insulating your garage door can increase energy efficiency and maintain a comfortable, moderate temperature, sealing your garage off from outdoor temperatures that sneak into your space. Some of the most popular and energy-efficient insulators for garage doors include:

  • Aluminum: A lightweight option requiring minimal maintenance, an aluminum garage door can hold up against weather and resist rusting in coastal climates.
  • Fiberglass: Fiberglass garage doors are also lightweight and reliable with low maintenance requirements. The finish on most fiberglass doors resembles natural wood. 
  • Steel: Steel-insulated garage doors are highly durable, long-lasting and dent-resistant, capable of withstanding the elements. However, they can corrode in coastal climates due to high salt concentration in the air, so it’s essential to treat them correctly and have the paint professionally refinished if chipping occurs.
  • Wood: While wooden garage doors are typically the most costly, they offer value and a luxurious appeal to your home. They require additional upkeep and resealing to prevent mold, mildew and pests, but they can be durable and long-lasting with proper maintenance.

6. Cool Your Vehicle Before Parking

Your car heats up with use, so when you park it in the garage as soon as you arrive home, it warms up the air in your garage. Closing the garage door traps the hot air in the space, increasing the overall temperature considerably.

Instead of parking the car in your garage immediately, try leaving it in the driveway first to cool off for an hour or two — preferably in a shaded spot, if possible. Leaving it in a sunny spot can continue to heat the car. If parking your vehicle in a driveway isn’t an option, try pouring cold water over the roof of the car to accelerate the cooling process before you move it into the garage.

7 Weatherproofing Tips to Keep Your Garage Warm

Checking that your garage door’s seal is tight is incredibly important, especially during the winter months when the goal is to keep the extreme cold out and utility bills low. You may be surprised to know how much warm air escapes through your residential garage door, especially if you haven’t regularly maintained it. There are ways to resolve this issue, and it starts by making time to weatherproof your garage space well before the flurries start flying.

There are ways to resolve this issue, and it starts by making time to winterize your garage space well before the flurries start flying.

It’s never too late to make necessary repairs or to invest in proper winterizing solutions to help keep the warmth inside where it belongs. The garage door service experts at AAA Garage Door, Inc. have some garage door weatherproofing tips for Omaha homeowners looking to tackle some of the things that can cause garage spaces to become a drain on heating costs during the colder months.

How To Weatherproof Your Garage Door 

tips to make your garage door warm

It doesn’t matter if you want to get ahead of the game this winter or you’re trying to seal your garage door with snow already on the ground. These seven garage weatherproofing tips will help!

1. Inspect and Replace Garage Insulation

Homeowners sometimes forget that an insulated garage door can make a big difference in containing the warm air that your HVAC system generates. Insulate the walls and the garage door to save money on your energy bills and keep your garage warm in the winter.

Fiberglass batt insulation is a relatively inexpensive solution for the walls, but does require some skill to install correctly. Many of the worn-out wood, aluminum or metal garage doors aren’t conducive to adding insulation. Instead, look for new overhead doors that feature integrated polystyrene or polyurethane insulation. You can also get garage door insulation kits to add insulation to your existing garage door if it’s not that old.

2. Replace Weatherstripping and Seal Cracks and Holes

The weatherstripping seal around your garage door takes the brunt of harsh weather and repeated opening and closing, which can cause them to become brittle and crack or break. During winter, the rubber stripping on your garage door can freeze to the ground or threshold, causing it to rip, tear or cause the lifting mechanism to work harder to do its job. If you find that your garage door weatherstripping has any visible damage, it’s best to replace your garage door weather seals before the winter comes.

You’ll also want to remove any snow or ice from the area where your door seals. Ice chunks or snow clinging to the door can interfere with the photo-eye sensors, which could cause the door to come partially down, then go right back up without closing. If you choose to remove the old weather stripping seal and apply a new weatherstrip, use a high-quality product designed to remain pliable at any temperature.

After installing new weatherstripping, take a moment to inspect the garage walls and the areas around windows and doors where small cracks or openings are creating cold drafts. Caulk and seal those areas to minimize heat loss and seal any gaps that might’ve formed.

3. Check the Moving Parts of Your Garage Door

Overhead garage doors rely on several metal pieces to operate, such as the rollers, hinges and tracks. Metal contracts and could break when the temperature gets cold. As a result, your Omaha garage door could start to perform poorly or even stop working altogether. Rollers in particular can become brittle in cold air, causing them to crack. If the door doesn’t open or close correctly, it could let in cold drafts in the winter.

Explore your garage door and look at the various moving parts to make it last longer. If you see anything that appears broken or out of place, it’s time to repair those pieces before the cold weather starts.

4. Inspect Weatherstripping Between Garage Door Panels

This tip only applies to some garage door designs. If your garage door has room to install weatherstrippings between the individual door panels, we recommend you use v-shaped garage door weatherstripping. This protective seal will significantly increase your garage door’s energy efficiency to maintain heat in your living space. V-shaped garage door weatherstripping isn’t the same as bottom weatherstripping and side weatherstripping. This garage door weather seal is located between each door panel and provides the door and your garage with extra insulation.

5. Install an Automatic Wi-Fi-Enabled Garage Door Opener

Sometimes cold drafts may enter your home because you forgot to close the garage door. An open garage door leaves your home exposed to the elements. One simple home improvement to keep your garage warm in the winter is to replace your outdated garage door opener with an automatic one. Most modern models allow you to create a recurring schedule so your garage door will close automatically after a certain amount of time.

By connecting your opener to your smartphone or mobile device, you can check that you closed your garage door and receive alerts when it opens. You can also use the app on your smartphone to check whether your garage door is out of alignment or needs maintenance that you’ll have to address.

6. Replace Your Garage Door

You may need to replace your old, worn-out garage door with a new, energy-efficient one. If your garage door is several decades old or has severe damage from rain, snow, hail, or wind, a new garage door can help keep you warm in the winter. Even though a new door may be a significant investment, it’ll allow you to save money on your energy bills over time, so it’s well worth the investment.

If you’re going to get a new garage door, make sure you find one with excellent thermal insulation. Look for a garage door with a high R-value that demonstrates the effectiveness of reducing heat transfer. Depending on your local area, you should find garage door insulation of at least 10 to keep out the cold weather in the winter. A highly insulated door can protect your vehicles as well as your maintenance fluids and paints. You may also want a new garage door if you use your garage as a workspace.

Consider a material that can keep the cool air out and the warm air inside. Wooden garage doors are naturally insulative, while steel garage doors are compatible with the polystyrene or polyurethane insulation sheets available on the market today. Consult a garage door technician for the options available to you in your local area.

The Importance of Insulating Your Garage Door

The Importance of Insulating Your Garage Door

A properly insulated garage door prevents warm air from escaping your garage during the cooler months and hot air from entering during the warmer months. The increased insulation helps decrease your energy usage and provides many other benefits for your garage, home and wallet. Since your garage door is the largest opening to your home, it must have sufficient insulation, or you’ll experience drafts, extreme temperatures and energy loss. 

You have a few options available if you’re looking to insulate your garage door. You can choose to go the DIY route with an insulation kit, contact a professional garage service to upgrade your current door or replace your old door with an energy-efficient replacement. If you opt to get a brand-new door, you can compare many options to add insulation and style to your home. Modern garage doors add significant curb appeal and value to your home. 

Older or poorly insulated garage doors can lead to various problems in the home. For example, water can build up in your garage after a rainstorm or high-humidity days. The water trapped inside your garage struggles to evaporate, and it can cause mold to develop throughout your home and your possessions. A buildup of water in your garage can also lead to condensation forming in your vehicles’ crevices and electrical circuits, leading to faster deterioration over time.

6 Benefits of Insulating Your Garage Doors

6 Benefits of Insulating Your Garage Doors

Why insulate your garage door? Doing so brings many advantages and allows you to recoup your initial investment through increased energy savings and protecting your home and belongings. Here are six of the most significant reasons to insulate your garage door. 

1. Increase Energy Efficiency 

Is your garage cold in the winter and hot in the summer? Even if you have insulated your garage’s walls, your garage door may be causing a significant energy drain. An insulated garage door will help seal your garage off from the outside temperatures that sneak into your home through your garage. You should notice a decrease in your heating and cooling costs when you insulate your garage doors. Hot or cold air can enter the rest of your home when your garage is at a higher or lower temperature, which results in your A/C and heating units having to overcompensate and operate more often. 

Insulating your garage door will help keep your garage at a moderate and comfortable temperature — not too hot and not too cold. Another benefit is that you can work in your garage year-round, due to the more comfortable temperature.

2. Notice Quieter Operation

Older and uninsulated garage doors can make loud noises when you operate them, while insulated garage doors are much quieter. You can resolve the abrasive creaking and rattling by insulating or replacing your garage door. For many uninsulated garage doors, the sounds you’re hearing may be from the panels on the door vibrating and creating noise. Panel vibration can be worse for more lightweight garage doors. Solve this problem by insulating your current door or replacing it with a new, high-quality one. The insulation prevents the tiles from rattling and will cut down on the noises you hear when operating the door.

3. Boost Door Strength and Durability 

Is insulating a garage worth it? Insulated garage doors consist of more durable materials than uninsulated ones, making them suitable for long-term investment in your home. Insulated doors should require less frequent maintenance and repairs. The materials’ strength also makes the doors more resistant to damage like dents or warping. The constant opening and closing of garage doors can wear them down over time, but an insulated garage door will long outlast an uninsulated one. Many insulated garage doors have a steel or aluminum frame with solid insulation on the interior, making them sturdy, lightweight and durable enough to withstand the elements.

4. Protect Your Car and Belongings 

Installing an insulated garage door is vital if you want to protect your car and other belongings you keep in your garage. Extreme heat, cold and humidity can damage your possessions, leading to costly repair bills or permanent damage. Your garage will stay at a relatively consistent temperature throughout the year if you have an insulated garage door. Keeping your car in a controlled environment will help prevent wear and tear from temperature fluctuations. 

Insulated garage doors are also helpful in keeping water from coming into your garage. Water struggles to evaporate once it enters your garage because it has nowhere to go, and the lingering water increases the humidity levels. High humidity and condensation can make your tools rusty, damage your vehicles’ electrical components and cause mold to develop in your walls or on items you store in the garage. An insulated garage door will form a tight seal with the garage floor, which will prevent water from entering. 

5. Reduce Noise

Insulating a garage door helps keep external sounds out and internal ones in. The thick insulation will do wonders for noise reduction if you live in an area with nearby neighbors or a busy street. Working in your garage can be noisy, and an uninsulated garage door doesn’t do much to prevent loud noises from leaking out. You can avoid irritating neighbors with loud power tools because the insulation will keep the noise contained. 

6. Increase Curb Appeal 

You can replace your garage door with a modern, insulated door that will elevate the appearance of your garage. Your garage is one of the most visible aspects of your home, and a high-quality garage door can elevate the curb appeal. An appealing garage door will also boost your home’s value, and you’ll see a return on your investment, whether you’re planning on living in your house for years to come or are considering selling soon.

Does Insulating a Garage Door Help You Save Money?

Does Insulating a Garage Door Help You Save Money? 

Installing an insulated garage door will generate immediate savings due to the increased energy efficiency of insulated vs. non-insulated garage doors. Insulating a garage door makes the most difference for your savings if you live in an area that experiences extreme temperatures and have an attached garage. Attached garages pose the most significant energy drain because your home probably shares at least one wall with the garage. 

Freezing and scorching temperatures that enter your garage through uninsulated garage doors will leak into the rest of your home through the walls and house doors, which causes your home’s internal temperature to fluctuate. Your cooling and heating systems will have to compensate to restore the correct temperature, causing higher energy usage and mechanical strain.

Ultimately, the amount of money you save on your energy bills will depend on where you live and how much heat loss occurs from your garage door. Living in an extremely hot or cold climate makes insulated garage doors worth it.

Types of Insulated and Energy-Efficient Garage Doors

Types of Insulated and Energy-Efficient Garage Doors 

The type of insulated garage door you choose depends mainly on your climate, aesthetics and how much you’re looking to spend. If the garage door has the necessary amount of insulation for your environment, any insulated door should suit your needs. Most insulated garage doors are multilayered and have a thick layer of insulation within the frame. Here are the most common types of insulated and energy-efficient garage doors. 

  • Steel insulated garage doors: Steel insulated garage doors have an insulating layer inside the steel frame. The steel results in a very durable door that is dent-resistant, long-lasting and able to withstand the effect of the elements. Steel doors can corrode and rust in coastal climates due to the high salt content in the air, so it’s vital to treat them properly and have the paint refinished if any chips occur.
  • Aluminum insulated garage doors: An aluminum garage door is a great, lightweight option that requires little maintenance. Aluminum will hold up against weather and won’t rust in coastal climates as steel doors may. Aluminum’s lightweight nature makes it particularly helpful for older adults who may struggle to lift a manual garage door.
  • Fiberglass insulated garage doors: Fiberglass garage doors are another reliable and lightweight option with low maintenance requirements. The finish on most fiberglass doors looks like natural wood, so it’s an excellent option if wood fits your home’s aesthetic. 
  • Wood insulated garage doors: Wooden garage doors tend to be the most expensive, but they offer a luxurious look and add value to a home. Wood requires more upkeep than other options because you need to reseal it to prevent mildew, mold and pests. However, you’ll enjoy wood doors’ durable, long-lasting nature if you follow the maintenance schedule.

Other Factors Affecting a Garage Door’s Energy Efficiency

The type of door you choose is less of a factor than garage door insulation ratings, windows and the door’s size. Let’s dig into what this means.


An R-value is a measurement of how effective insulation is at preventing heat loss. The “R” stands for the resistance a material has against heat flow. A higher R-value means the material limits more heat than one with a lower R-value. A lower insulation R-value will result in more garage door heat loss than a higher-value one. 

Some garage door manufacturers measure the R-value in different areas than other companies, making it challenging to accurately compare the insulation value of different branded garage doors. When a manufacturer provides an R-value based on the entire door, the values will be lower than those measured from the center panel. 

Because the R-value doesn’t have a consistent measurement method, it’s not a reliable indicator of the insulation’s thermal efficiency. 


The U-value — sometimes referred to as U-factor — is a helpful alternative to the R-value because it measures the entire garage door’s insulation. This form of measurement is much more reliable because some parts of the door, such as the frame and seals, can’t have the same degree of insulation as the panels. Insulated garage door U-factors account for this and provide a consistent figure across all manufacturers. 

U-values range from zero to one, and lower numbers indicate better insulation than higher ones. 

Garage Door Insulation: Polystyrene vs. Polyurethane

There are two main insulation types found in garage doors.

  • Polystyrene: Polystyrene is similar to Styrofoam, but it’s more condensed, so it offers superior insulation properties. Garage door manufacturers typically glue sheets of polystyrene to the garage door panels. Gluing the insulation causes some areas like the panels’ corners to have air pockets, which reduces the insulation. Polystyrene can deteriorate if exposed to chemicals such as bug spray or gasoline.
  • Polyurethane: Polyurethane, another form of garage door thermal insulation, gets sprayed directly inside the garage door frame, resulting in a much more thorough application of the insulation and higher U-value. Polyurethane is very fire-retardant and won’t melt if exposed to fire. It can withstand temperatures up to 700 degrees Fahrenheit before it begins to char. It’s also resistant to all chemicals, oxidation and sun damage. 

Both materials will age well and not deteriorate over time if the door remains in good external condition, but polyurethane will hold up better when exposed to stressors. While polyurethane offers better insulation, it also costs more on average than polystyrene. 


Windows in a garage door can add visual appeal, but glass is a poor insulator. If you’re in a climate that gets very hot or cold, you should consider getting a garage door without windows. Garage doors will have energy-efficient windows, but they’re still not as insulated as a standard insulated garage door will be, and heat will transfer through the glass. 

Correct Garage Door Size

It’s vital that the garage door fits correctly and forms a tight seal against the ground and the sides of the garage to prevent wind and cold air from entering. If there are any gaps, your insulated garage door will be much less effective because the air will still have a place to escape.

3 Effects of Cold Weather on Garage Door Openers

Cold Weather Impacts Garage Door Openers

Your garage door opener may struggle to open the door in cold weather, which could lead to breakage or higher energy costs. In some cases, garage doors may stick in cold weather, meaning the opener may not be able to open the door at all.

The question is, what steps can you take to maintain the integrity of your garage door and garage door opener in cold weather?

a garage door covered in snow

How Cold Weather Affects Garage Door Openers

Is it too cold for your garage door to work correctly? Many homeowners ask this question when winter weather hits and they notice a slowdown or malfunction of their garage door opener. Cold weather can have different effects on your garage door based on fluctuations in precipitation and temperature.

Your garage door system is a machine. Like any other machine, it has moving parts. Temperature changes are notorious for the impact they have on interconnected components. Cold weather, especially, can have a significant effect on your garage door opener.

Cold Weather and Garage Door Openers

The 3 effects of cold weather on garage door openers are:

1. Garage Door Openers May Lose Lubrication and Connectivity

Garage door openers can lose some of their lubrication in cold weather, which may cause them to work harder. When you properly lubricate your garage door opener, you minimize the strain on the motor. A professional technician can assist you in finding the best lubricant for your garage door parts.

Frozen lubricant can be another reason a garage door opener doesn’t work in cold weather. Replacing the frigid product with a fresh lubricant should solve the problem. You can prevent this issue by choosing a product designed to withstand extreme temperatures.

The photo-eye sensors on your garage door can also become fogged over due to the cold. When this happens, the garage door may think there is an obstruction in the way even if there isn’t. This lack of communication between the sensors can cause malfunctions with your garage door opener. Luckily, all you have to do in this situation is wipe off the lenses.


2. Garage Doors Contract in Cold Weather

Garage doors — mostly those made of steel — contract in cold weather. Other metal garage door parts, such as rollers, hinges and springs, can warp if they’re not moved regularly in the cold.

You can minimize the effects of garage door contraction by keeping it lubricated throughout the winter. Apply a silicone-based lubricant to the springs, rollers, hinges and other moving parts

At AAA Garage Door, we recommend scheduling annual maintenance before winter begins and lubricating your garage door’s moving metal parts to keep them working properly.

3. Garage Doors Can Freeze to the Ground

When water freezes during the winter months, some garage doors freeze to the ground, especially if puddles form at the bottom. Garage doors are designed to seal to the ground in an attempt to prevent weather and small animals from coming inside. In cold weather, though, this can cause the door to stick.

How Do I Keep My Garage Door From Freezing To The Ground?

To help prevent your garage door from freezing to the ground, push away any collected water from the bottom of your garage door as often as possible, lay down salt, and lubricate your garage door.

Other steps to prevent a freezing garage door in cold weather include:

  • Use lubricant: Applying a silicone-based lubricant — not grease — to the door’s bottom rubber seal will prevent it from sticking to ice.
  • Sprinkle salt: Ordinary table salt can keep the water on the inside and outside of the door from freezing.
  • Clear snow: Removing snow near the door will eliminate issues with melting and refreezing that could cause sticking.
  • Install insulation: An insulated garage door prevents warm air from escaping, helping to combat freezing by maintaining a higher temperature.
  • Upgrade the weatherstripping: Inspect the weatherstripping at the bottom of the door and replace it if you notice cracks or other signs of damage.

How Does the Cold Affect Keypads?

The keypad enables you to open or close the garage door without using a remote control or key. However, its location outside the door exposes the keypad to the elements. Just like extreme cold weather can keep your car’s battery from starting the vehicle, the same can occur with a keypad’s battery. Freezing temperatures can cause the batteries to run down faster than in warmer weather and require more frequent changes.

If your garage door keypad is not working in cold weather, your first step should be to replace the battery. If that doesn’t resolve the issue, contact a professional garage door technician to inspect the electrical wiring and other components.

Energy-Efficient Garage Door Buying Guide

When the frigid weather sets in, many homeowners look for ways to help control heating costs. While you can do many things to lower those utility bills, an often overlooked area of the home is the garage and the overhead door that stands between your family and the outside elements.

This article explains how energy efficiency for garage doors is measured and how your unique situation determines the amount of insulation needed. Besides investing in a brand-new door, you should have a professional examine your residential garage door for issues such as poor insulation, worn or missing weatherstripping and higher long-term heating and cooling costs. If you need a replacement, we offer plenty of energy-saving garage doors for your selection.

How Do You Measure Garage Door Efficiency With R-Value?

Most of us know that insulation is essential to keeping our garages and homes more energy-efficient. However, you may not realize that insulation is not a “one size fits all” solution, especially when it comes to Omaha residential garage doors. There are many issues to consider, from thermal resistance factors to appropriate R-values, and each will directly impact just how must energy efficiency can be expected.

What Is the R-Value?

The R-value is an industry standard for measuring the thermal resistance of certain construction materials. This measurement takes into account thermal conductivity, which is the ability of cold or heat to pass through a wall. The higher the garage door R-value, the greater its insulating properties.

Most of the garage doors we offer have R-values ranging from 6.3 to 20.4, depending on these qualities of the product:

  • Thickness: We provide a selection of garage doors that range from one-layer to five-layer construction to enhance energy efficiency.
  • Material: Some materials, such as wood, are natural insulators, but others need an additional layer of insulation to be effective.
  • Type of insulation: High-quality insulation materials can make your garage door more energy-efficient.

When Should I Increase My R-Value?

Knowing which R-value is best suited to your needs depends on a variety of things, including whether your garage is attached or detached. Invest in a garage door with a higher R-rating for garage insulation in the following conditions:

  • You have an attached garage: An attached garage often has a door leading into the central part of the house. Energy-efficient garage doors can prevent heat from seeping through this entry so your home can be comfortable in harsh weather conditions.
  • You want to lower your home’s energy costs: Since the garage makes up such a large portion of your house, its opening can bring in or release heat if it’s not energy-efficient. As a result, your HVAC system will have to work harder to maintain your house’s temperature. To save money on energy costs, get a garage door with a high R-value.
  • You spend a lot of time in the garage: You might have a workshop or office in your garage that requires you to spend a lot of time in it. Even if you only use it to park your car each night, you probably want a comfortable place to step out and go into your house. A garage door with a high R-value can ensure you have a pleasant environment when you’re spending time in the garage or coming home from work.

explaining which r value is best for different situations

Which R-Value Is Best for My Garage Door?

If you fall into one of the categories above and want to increase your home’s R-Value then it’s important to understand what R-Value is best for your garage.

  • We recommend an R-Value of 0-6 for detached garages.
  • We recommend an R-Value of 7-9 for an attached garage.
  • We recommend an R-Value of 10-13 for heated garages.
  • We recommend an R-Value of 14+ for a garage that’s used as a living space or shares a wall with a living space.

What Is the Most Energy-Efficient Garage Door Material?

If you want an energy-efficient garage door, you’ll want to select a design with energy-saving material. You can choose any door to complement your exterior property, but if it’s not energy-efficient, you’ll have to add a layer of insulation. Consider which insulation and material would work best for your property.

Energy-Efficient Garage Door Insulation Materials

Even if you choose a material that doesn’t have adequate insulation qualities, you could add layers of insulation to increase your door’s energy efficiency and durability. We offer the following insulation materials that make your garage door energy-efficient:

  • Polyurethane: You can add a layer of energy-efficient Intellicore® polyurethane to your Clopay® residential garage door. The manufacturer injects a polyurethane foam between the door’s layers so it fills every crevice. As it expands, the foam bonds to the frame to enhance the door’s durability. Polyurethane also offers a high level of sound isolation and can help regulate the temperature if you live in a harsh climate and enter the house through the garage door.
  • Polystyrene: Even though polyurethane insulation foam is much more energy-efficient than polystyrene, you can consider polystyrene if you’re on a tight budget. This material comes in rigid panels that the manufacturer inserts between the layers of the door or inside your single-layer product, with a vinyl back that holds it in place. If you have a budget-friendly single-layer garage door, you should invest in this type of insulation if you want a quieter door that lowers your monthly energy costs.

Energy-Efficient Garage Door Materials

The garage door material you choose depends on your local climate and your aesthetic preferences. As long as you have the right insulation for your selection, you can select any type of material for your garage door. Consider which of these materials would best complement your property:

  • Steel: Insulated steel garage doors feature at least two metal layers with your choice of insulation placed in the center. You could also find a one-layer construction with a panel of padding on the back. Besides being energy efficient, steel is also resistant to warping, cracking and harsh effects from the elements. Keep in mind that steel can corrode in coastal climates without the proper treatment.
  • Wood: Eco-friendly garage doors made from wood contain two layers of wood with your choice of insulation tucked inside. A wooden product gives your home a natural, luxurious appearance. If you live in a humid climate, wood could rot or warp from moisture damage, so you would need to treat it or invest in a moisture-resistant wood species.
  • Composite: Wood composite panels often complement a steel garage door’s design because it looks like natural wood. Faux wood cladding offers a layer of insulation that can make your garage more comfortable in harsh weather conditions.

Carriage house garage doors tend to be the most energy-efficient because of their layers of various materials. We also offer some modern doors that can complement your home outside while providing a comfortable temperature inside. Browse the design brochure to determine whether you can get 2-inch Intellicore® polyurethane, 2-inch polystyrene or 1 3/8-inch polystyrene insulation. Besides your choice of polyurethane or polystyrene insulation, you can also get WINDCODE® reinforcement if you live in an area with heavy winds.

Do Insulated Garage Doors Save Energy?

An insulated garage door saves energy and lowers the cost of your monthly utility bill. However, you should consider more than the material and layers of insulation. Even with a high-efficiency, well-insulated Omaha garage door, your garage can’t save energy if other repair issues need addressing. If you want an energy-efficient garage, you should also:

  • Insulate the walls of your garage to reduce heat loss.
  • Regularly inspect and repair gaps between the sections or joints of a door or frame.
  • Replace worn weatherstripping on the bottom of the overhead door and around the perimeter.
  • Use quality weatherstripping and siding materials designed to remain flexible in all kinds of weather and temperatures.
  • Invest in a smart garage door opener connected to your phone to help you close the door, even after you’ve left the house.
  • Make sure a professional garage door technician installs your unit securely and correctly.
  • Order energy-efficient windows to go along with your garage door.
  • Install high-quality hardware — including the track, frame and rollers — so your door rolls into place and doesn’t leak air when it operates.

the benefits a energy efficient garage door gives you

Is an Energy-Efficient Garage Door Worth It?

Even though an insulated garage door has a higher upfront cost, you’ll save money in other ways. Here are some of the reasons why you should invest in an energy-saving garage door:

  • Increase your property value: If you plan on selling your property, an energy-efficient residential garage door can add value to your home. Potential homebuyers enjoy an energy-efficient house because it means they’ll save money while they live in it. Besides having an aesthetic appeal, a brand-new component to your property will make your living space more valuable.
  • Reduce heat loss through your garage: If you have an attached garage, it shares a wall with one of your interior rooms. Any energy lost in your garage could affect the temperature of the whole house. Even if your garage isn’t insulated, an energy-efficient garage door controls the transfer of heat.
  • Better sound isolation: Besides keeping in heat, well-insulated garage doors can also block sound. You can have privacy in your home without disturbing your neighbors, and you can sleep better at night without hearing the noise from outside. An insulated door also operates quieter, so you don’t have to disturb the whole house when you run it.
  • Save money on utility costs: When you’re able to control the transfer of heat into and out of your garage, your HVAC system doesn’t have to work as hard to maintain your home’s temperature to save money on your monthly utility bill.
  • Protect your car battery: When you come home, you store your vehicle in the garage to protect it from possible weather damage. When the temperature in your garage is too hot or cold, it could damage your car’s battery and reduce its lifespan. If you invest in an insulated garage door, you can keep your vehicle running for a longer time.
  • Keep your home comfortable: When the inside air is the same as the outside, it can get stuffy in the summer and frigid in the winter. Instead of piling blankets on to stay warm, you can invest in an insulated garage door to help maintain a comfortable atmosphere throughout your living space.
  • Protect your door from weather and intruder damage: Garage doors with insulation are typically more reliable and durable than ones without it. If you live in a climate with harsh weather conditions, you may want an insulated garage door to protect your valuables from hurricanes, blizzards or floods. You could also repel intruders who try to break in through the weak spots of your door.
  • Make better use of your garage: If you use your garage for more than just storing your vehicle or entering the house, you should have an insulated garage door to provide a pleasant environment while you work.
