When you change the exterior door on your home, it can do wonders for your curb appeal.

But adding a new door does more than just make your house look nice, it can also save you a ton of money on energy costs if you use the right one.

Before you shop for a new exterior door, check out this guide that’ll show you more about the most energy-efficient exterior doors available today.

Make Some Simple Swaps

If you have an older home, you like have an older exterior door, too. Just by switching to a newly manufactured door, you’re likely to get one that’s much more energy-efficient.

Today’s new door models are made to fit into place much better than their older counterparts. This means you’ll get better efficiency automatically simply because there will be fewer gaps between the door and the frame.

Make sure you choose energy-efficient exterior doors that work well in your particular climate. You should also find one that suits your home’s specific design.

Another simple switch you can make is to ditch the screen doors. Get rid of the screen door, and replace it with a storm door. These types of doors have extra insulation which translates into better energy savings for you.

A screen door offers zero insulation which leaves your home susceptible to energy loss right through the front door. By getting rid of this type of door and replacing it with a storm door, you’ll automatically experience better energy efficiency.

Select Your Door Material Wisely

When it comes to new exterior doors, the type of material it’s made out of really matters. There are plenty of different types of doors available, so let’s take a closer look at each:


This material does not conduct heat and electricity very well. Because of this, there are many advantages of fiberglass doors. This material offers up to almost four times as much insulating R-value than many other doors, such as a wood door. Fiberglass is also very weather resistant, so the amount of heat loss will be reduced.


Just like windows, vinyl doors are quite energy efficient. This material provides excellent thermal insulation, meaning it easily blocks hot and cold air from getting into your house. It’s also great for retaining the inside temperature, which can help lower your heating and AC costs. You can even choose vinyl doors that have a wooden look for a stylish touch.


Steel is an extremely heavy-duty material that works fairly well as a thermal insulator. However, steel is also a very good conductor of heat. This means you’ll feel the heat or cold whenever you touch the door, so be aware.


While wood doors look great, they’re not very good at being energy efficient. Wood is a poor insulator of heat, so this type of door is usually not ideal if you’re looking for something energy efficient. Wood absorbs heat and may even cause heat flow, which means you’ll spend more money trying to keep your home cool in the summer.

Whichever door you choose, they likely have a core filled with a material called polyurethane. This material is a foam that can help to further insulate the door and increase its overall energy efficiency.

Using Glass for Energy-Efficient Exterior Doors

Glass doors look great, and they’re still a popular choice for many homeowners. Some doors have glass panes that give them a decorative touch and more natural light for the home.

If you adore glass and want an exterior door with glass panes, don’t fret. There are some new, energy-efficient options available.

Look for glass doors that have a low-E coating since these are highly energy efficient. These glass panes reflect most of the heat outside away from the home.

Check the perimeter of the glass to make sure it has adequate weatherstripping. This will help to prevent or even completely eliminate any possibility of excess airflow. Weatherstripping is highly effective at keeping the air blocked for increased insulation.

When you look for a glass exterior door, make sure it’s Energy Star rated. This rating will ensure that your beautiful new glass exterior door is properly manufactured for maximum energy efficiency.

And of course, no matter which type door you choose, you should enlist the help of a door installation professional if you can’t do it yourself. Many companies are able to not only install the door, but they’ll also help make recommendations for other ways you can save on energy costs.

A good rule of thumb for any new door is to ensure that it’s installed properly to avoid gaps and air escaping or getting into the home. Whether it’s glass, vinyl, or fiberglass, your new door should be able to help you save when it comes to your heating and cooling bill.

A New Door Equals Energy Savings

Whether you’re trying to spruce up your home or you’re tired of pesky drafts, it’s important to choose energy-efficient exterior doors. The good news is that almost all newer doors are great at keeping your warm air inside during the winter and cool air inside during the summer.

Check the door you’re interested in to see if it is Energy Star rated. When in doubt, ask a professional who can give you insight on the right door for your needs.
