Whether you’re building a new home or renovating an existing one, energy-efficient doors with strong insulating capabilities will keep the outside temperature from infiltrating your inside space. Inappropriate heat exchange and air and temperature leaks are prevented by energy-efficient doors, ensuring that the energy required to heat and cool your home does not go to waste. The most energy-efficient doors operate as a barrier between the temperature within and without your home, allowing you to save money on your energy bills.

We will explore some of the critical elements that will help you choose the most worthwhile energy-efficient door for your home.


What Is R-Value?

The R-Value is the insulation rating of material for every inch of its thickness. Using the R-Value you can determine how much a type of insulation can block heat from escaping or infiltrating. Insulation materials may possess different R-values based on their type, thickness, and density. 

In general, a higher R-value for insulation means that your home will enjoy improved climate control and become energy-efficient. A greater R-value in insulation is usually associated with a higher price tag.

Verify the R-value for every inch of thickness specified by the manufacturer for each type and substance of insulation you consider. In general, the installation technique of insulation can provide you with an indication of how it compares to other forms of insulation.

What are the types of insulation? 

From lowest to greatest average R-value per inch, the following insulation methods are available:

Take note that the R-value of the insulation will vary depending on the material used.

What Type of Door Is Most Energy Efficient? 

It is not straightforward to pinpoint a specific door type as the most energy-efficient. Other particular elements are critical for consideration before giving a conclusive standpoint. It is best to look into the door’s location and material to determine the door that fits this category.

Energy Efficiency of Doors Depending on the Location 

A door’s location will determine the elements it encounters. All these imply that the door’s location will dictate the degree of insulation required and the material that can best withstand the prevailing climatic conditions to ensure the door’s energy efficiency.

Energy Efficient Front Doors 

Whenever your entry door gets subjected to relentless, scorching summer sun or unrelenting winter gales, the insulation capabilities of the entry become even more essential than the door’s protection from high and low temperatures in general. To keep your home pleasant all year long, an entry door exposed to more harsh elements from Mother Nature will have to be capable of withstanding higher temperatures in extreme weather situations. You will thus need to install a thermally efficient front door.

High R-value exterior doors tend to be the best when selecting an entry door. Fiberglass doors are a more excellent choice since they have the highest R-value of 10 or 12. The insulation provided by fiberglass doors is five times greater than wood doors. They can endure various temperatures and weather conditions, including high winds, high humidity, and steady rain. 

Wood and steel doors decay, crack and split, but fiberglass doors do not. Fiberglass doors will not rot, crack, or split, and they will not corrode or rust. The use of a fiberglass door will remove the need for costly and aggravating damage management in the future, which will save money in the long run.

Energy Efficient Internal Doors

Insulation is absent from the majority of internal doors. That’s acceptable for specific rooms, but in some interior locations, such as a door to an attic, where drafts may be present, you may want to consider installing an outside insulated door.

Doors made of solid wood. When utilized in the interior of a home, solid wood doors are both aesthetically pleasing and long-lasting. They are, however, significantly heavier than alternatives and are susceptible to warping under certain situations.

Doors made of MDF. Because medium density fiber doors are lightweight and affordable, they are famous for home interior doors.

Hollow-core doors. They are lightweight and inexpensive and do not provide any insulation or soundproofing. Because they are not very durable, exercise caution when using them.

Energy Efficient Back Doors

Patio doors are typically made of glass to provide a clear view of the outside, making them less energy efficient than entry doors. However, this does not imply that energy-efficient patio doors do not exist! An excellent energy-efficient window shares many of the characteristics of the most fabulous energy-efficient patio doors:

Sliding glass doors are more energy-efficient than French doors, but you’ll need to keep a check on the seals, mainly if you use the door frequently. The friction caused by sliding the door open and closed might cause the seals to wear out over time, reducing the door’s efficiency.

Of course, energy-efficient French doors are available, but because both panels open (rather than just one as in a sliding door), their efficiency rating will be significantly lower than that of a sliding patio door. To reduce air leakage, replace any faulty seals on your French doors as soon as possible.

Regarding preventing sun fade on items, low-E glass or built-in shades placed between panes are good options. Whatever model door you choose, ensure it has double-paned glass and correct weather stripping to help you save money on heating and cooling bills in the long run.

Energy Efficiency of Doors Depending on the Material

The material used to make a door is critical to its energy efficiency levels since different materials have varying efficacy.

Energy Efficient Glass Doors

ENERGY STAR certified sliding glass doors are more energy-efficient than older doors with poor frames or only one pane of glass. You measure heat transfer rates by a number called the U-value, and higher U-values mean less efficient energy use. It takes four times as much argon gas to fill a single pane of uncoated glass than to fill an uncoated double pane with argon gas.

Sliding doors are great because they don’t take up much space, are easy to open and close, and let in a lot of light. But they do need a lot of attention. It can last for up to 30 years with the proper care. Keep the glass panes clean, take care of the tracks and runners, put screens on the doors in the winter, and remember to remove them in the spring.

A good design for a glass door frame that saves energy:

Sliding glass doors with windows filled with Argon or Krypton gas have very low thermal conductivity, making them ideal for sliding glass doors.

When you use Low-E coatings, there are two ways to get them to work. Manufacturers make hard coatings by putting a weak layer of metallic partings on the outside of the gas, while for soft coatings, they put them between the two panes of the window.

Both low-E coatings make homes more energy-efficient, but soft layers are usually the best.

Energy Efficient Wood Doors

For any home, a wood front door is a good choice. For a more traditional look, or if you want to add some style to your entryway, a wood door is a great option. But, are wood doors energy efficient? Wood has many natural energy-saving features that make it a good choice.

It can aid in protecting your home from the weather if you make your front door with wood. You’ll enjoy protection, especially with a solid hardwood door. A wood door will not be as energy-efficient as a high-end fiberglass door.

Moisture is the adversary of any wooden door. Although your wood exterior door has been well-kept, wood has a natural inclination to expand and constrict in high temperatures. It might cause warping and cracking with time, affecting how your door fits in the entrance. Furthermore, if your wood exterior door isn’t adequately maintained, moisture might leak through the door and cause it to rot. As a result, some homeowners prefer a fiberglass or steel door.

Energy Efficient Steel Doors

Steel front doors are very energy efficient. They wouldn’t be so popular in modern homes if they weren’t. Steel entry doors often outperform insulated fiberglass and wood doors in energy efficiency. Steel is effective in preventing heat loss because it has a thermal break.

Steel doors aren’t from solid steel. They are two pieces of steel with a thermal break on the inside. This section retains heat bett
r than the rest of the building. The weatherstripping also saves energy. You can get a superior seal by using mild magnetic weather stripping on steel doors. It reduces breezes and heat loss even around the edges of your steel door and extends the life of your weather stripping.

The thermal break further helps the steel doors muffle additional noise. So less street noise in your home, at least from the front door. Aside from looks, buying a steel entry door has many advantages.

Frequently Asked Questions

There are many questions that arise whenever they are looking for energy-efficient doors. The arising questions are critical as they help homeowners to make informed decisions on what they require for their homes. Here is a brief look at some of the most commonly asked questions on energy-efficient doors.

Which Doors Are Best for Insulation?

Fiberglass is the most insulating exterior door material. While a fiberglass door has a foam-like steel door, cheap maintenance makes it preferable. Fiberglass is also a good insulator, outperforming steel doors.

How Do You Know if a Door Is Energy-Efficient?

When choosing energy-efficient doors, it’s critical to analyze their energy performance ratings in connection to your home’s local climate and architecture. It will assist you in narrowing your options. Look for the ENERGY STAR logo to assist you in identifying energy-efficient goods that are appropriate for your climate.

The National Fenestration Rating Council’s (NFRC) mark makes it easy to compare the energy efficiency of doors. The label indicates the door’s solar heat gain coefficient (SHGC) and U-factor. These parameters will significantly help you in knowing a door’s energy efficiency.

How Do You Make a Door More Energy-Efficient?

You can take four essential steps to enhance your door’s energy efficiency:

Provided your door is in good condition, most energy loss occurs in the spaces around it, not through it. First, check the door’s hinges for tightness—loose hinges can generate spaces between the door and the frame. Fill up any openings around the doorframe with silicone caulk. (Remember to put caulk only on fixed parts. If the gap is more significant than a quarter-inch, fill it with a foam backer rod first.)

In addition to caulking, weatherstripping tightens spaces between the doorframe and the wall. Compressible foam or rubber weatherstripping is ideal for doors, as it will compress to provide the best possible seal. (Brass weatherstripping is an alternative to compressible weatherstripping, but it is more challenging to install.) Don’t forget the door’s bottom: Rubber or bristles door sweeps on the inside of the door, or a flexible threshold with an adjustable center bulb, can help seal the air gap.

Similar to storm windows, storm doors help reduce energy loss by adding an extra air barrier. Storm doors aren’t often essential or cost-effective because thick wooden doors are typically well-insulated; the National Park Service’s Technical Preservation Services suggests storm doors only in cold areas or with glass panels. If you opt to add a storm door, pick one that matches your home’s architecture.

Doors with glazing (sidelights, transoms, or inset glass panels) might lose more energy than solid-wood doors. Glass in and around your entry should be fastened appropriately and in good condition. In colder climates, you can add a quiet storm. Sidelights with wood-framed glass or even plexiglass give another layer of weather protection and protection for historic panes.
