Energy Efficient Exterior Doors

Guide To Your Homes Front Entry Door

Energy-efficient doors are designed to provide a tighter seal against the elements, ensuring that your heat and AC stay inside your home where they belong. This results in lower energy bills every month and improved comfort throughout the year. Door installation is a relatively simple process, but it’s important to choose a reputable door installation service to ensure that your doors are properly installed and sealed. 

Let’s look at the three materials entry doors are made of.

Fiberglass Doors

Our home improvement contractors always want to offer their customers the best possible products on the market, and when it comes to doors, fiberglass is hard to beat. Fiberglass exterior doors are among the strongest on the market, and they’re also some of the most energy-efficient.

A fiberglass door is a poor conductor of heat, making it energy-efficient on its own, but when insulation is added, it’s hard to beat. We install fiberglass entry doors with foam cores, which makes them even more energy-efficient. So if you’re looking for a door that will give you strength and security while also saving you money on your energy bill, fiberglass is the way to go.

Steel Entry Doors

When it comes to exterior door installation, metal doors are a popular choice, particularly steel. Steel is an affordable, thermal insulators, making them energy-efficient. However, they also conduct heat, so you’ll be able to feel the outside temperature if you touch the door.

Although they’re energy-efficient, they’re not quite as durable as fiberglass doors. Metal doors are highly susceptible to dings and damage.

Exterior Wood Doors

Wood entry doors are beautiful and classic, but they’re the least energy-efficient choice. Wood is a poor insulator and it absorbs heat more easily than other materials. It also contributes to heat flow, allowing outside temperatures into your home.

As a result, wood doors can increase your energy bills and make your home uncomfortable during extreme weather conditions. If you’re considering a wood door for your home, be sure to consult with an experienced wood door installer.

They can help you choose the right wood and sealant for your climate, and they can provide guidance on proper installation techniques. With their help, you can enjoy the beauty of a wood door without sacrificing energy efficiency.

Factors That Affect Your Entry Doors Efficiency

When remodelers are asked to make a home more energy-efficient, they often think of replacing doors and windows. But the main material is only part of what makes a door energy-efficient. The insulation, frame, glass, and weatherstripping all factor into the door’s R-value, U-factor, and overall energy efficiency. Let’s look at how each of these materials contribute. 

The type of insulation in the door will affect its R-value. R-value is a measure of how well a material can resist heat flow. The higher the R-value, the better the insulating ability. Foam cores, honeycombs, and fiberglass batts are all types of insulation that can be used in doors. 

The U-Factor

The frame also contributes to the door’s energy efficiency. The width of the frame affects the door’s U-factor. The U-factor is a measure of heat transfer and it is expressed as a number between 0 and 1. The lower the number, the better the door is at resisting heat transfer. A wider frame means there is less area for heat to flow through and therefore a lower U-factor. In addition to frame width, material also matters when it comes to frames. Metal frames are good conductors of heat and should be avoided if you are looking for an energy-efficient door. Wood frames are much better insulators than metal frames. 


The glass in the door also plays a role in energy efficiency. Low-e glazing is a type of glass that has a thin metallic coating that reflects heat back into the house instead of letting it escape through the glass. This helps to keep homes warm in winter and cool in summer. Doors with low-e glazing typically have a higher R-value than doors without it. 


Finally, weatherstripping helps to seal gaps around the door so that air cannot leak in or out. A good seal will help to maintain indoor temperatures and improve the door’s energy efficiency. When remodelers are selecting doors for their projects, they should keep all of these materials in mind in order to choose the most energy-efficient option possible.

So What is a Good R Value and U Value for a Front Door?

A solid wood door will have an R-value of R-2 or R-3. An insulated steel or fiberglass will have an R-value that is twice that of a wood door and around a R-5 to R-6, but in some as high as R-7.


EnergyStar has New Jersey split into two zones, Northern and North Central. Atlantic County, New Jersey falls in the North Central zone. For this zone they recommend a U factor of .17 for an opaque door and for doors with ½ windows a .25.

Are ENERGY STAR doors worth the extra cost?


Energy Star-certified doors can help to boost efficiency, particularly in extreme climates. In milder climates, weatherstripping existing doors can solve most leaks and is more cost effective than replacing the door. 


However, if you are replacing your door, you might as well install an energy star rated door. New entry doors can save the average homeowner up to 15% off their total energy bills. This means the door has no thermal breaks. EnergyStar doors are designed to be more energy efficient than traditional doors, and they can help you to save money on your energy bills. They are affordable Energy Star doors at Home Depot, if you shop there.

In addition, Energy Star doors are often made of higher quality materials, which can help to improve the look and feel of your home. So, if you’re in the market for a new door, be sure to look for the Energy Star label.

How Can You Make Your Existing Front Door More Energy Efficient?

Fill the gaps

Any handyman worth his salt will tell you that a good door is essential for a well-insulated home. But even the sturdiest door will be ineffective if there are gaps around the doorframe. These gaps can let in drafts, driving up your energy costs in the winter and making your home less comfortable year-round. 

Fortunately, there are a few simple things you can do to seal up these gaps and improve your home’s energy efficiency. First, make sure the door is hanging securely on its hinges—any looseness can cause gaps between the door and the doorframe. Next, you can use silicone caulk to fill in any gaps around the doorframe.

Remember, only use caulk on fixed—not moving—parts. Also, if the gap is larger than ¼”, fill it with a foam backer rod before applying caulk. By taking these simple steps, you will save money on your energy bills.


Any good handyman service will tell you that caulking and weatherstripping are two of the most important things you can do to seal up your home and prevent drafts. Caulking helps to seal gaps between the doorframe and the wall, while weatherstripping will tighten up spaces between the doorframe and the door.

Compressible foam or rubber weatherstripping is a good choice for doors, as it will compress to offer the tightest seal possible when the door is closed. If you don’t like the look of compressible weatherstripping, brass strips are another, more historic option, but are more difficult to install.

Don’t forget the bottom of the door: Rubber or bristled door sweeps installed on the interior of the door, or a threshold with a flexible center bulb, can help to prevent air leakage between the door and threshold. By sealing up your home in this way, you can keep it warmer in the winter and cooler in the summer,saving money on your energy bills.

So if you’re looking for a handyman service that can help you save money, be sure to ask about caulking and weatherstripping.

Consider an efficient storm door

Storm doors are an added layer of protection against the elements, and they can be a great way to improve the energy efficiency of your home. If you live in an area that experiences severe weather, a storm door can help to keep your home warm in the winter and cool in the summer. In addition, storm doors can also provide a measure of security, deterring would-be intruders. 

When selecting a storm door, it is important to choose one that complements the architecture of your house. A professional door installer should properly install the door. With proper installation and maintenance, a storm door can provide years of service and protect your home against the ravages of weather.

Adding a storm window to sidelights.

Doors that incorporate glazing in some form, such as sidelights, a transom, or inset glass panels, can be more susceptible to energy loss than their solid-wood counterparts.

To prevent energy loss, make sure that any glass in and around your door is properly secured and in good condition. You can also add a simple storm door for extra protection against the elements. Wood-framed glass or even a plain sheet of plexiglass secured around sidelights adds another layer to both buffer the weather and protect historic panes from damage.

By taking these measures, you can help ensure that your front door is energy efficient and up to the task of protecting your home from the elements.

Storm doors are commonly viewed as an inefficient investment in energy savings, and while this may be true to some extent, there are many advantages to installing some extra weather protection. Storm doors serve as an excellent buffer between the outside elements and your home, providing an extra layer of insulation while protecting your primary entry door from the elements.

In addition to energy savings, storm doors can provide many other benefits, such as improved home security, fresh air circulation, and reduced insect infiltration. If you live in an area with moderate weather conditions, a storm door is definitely worth considering.
