Planning to buy a new exterior door? Switching to energy-efficient front doors makes excellent investments for old and newly built homes. Energy-rated doors provide better functionality, security, and comfort for your family than traditional entryways.
Choosing a front door is also an opportunity to showcase your personal taste and make your home more inviting to guests.
In this guide, we covered everything you need to know about energy-efficient doors and how to choose the best front door for your home.
What is an energy-efficient front door?
Energy-efficient front doors are exterior doors designed to minimize heat transfer, reducing your home’s utility costs. It also prevents drafts, or when air passes from the outside into your home and vice versa.
Depending on materials and construction, energy-rated doors have varying levels of heat resistance.
Compared to traditional doors, energy-rated front doors are more eco-friendly and long-lasting.
Why do energy-efficient doors matter?
Energy-efficient doors matter in enhancing your home’s efficiency through the following ways:
- Better comfort. Energy-rated doors help maintain consistent indoor temperature for your family’s overall comfort. Your home remains warm during winter and cool during summer.
- Financial savings. According to the U.S. Department of Energy, energy-efficient fenestration products, such as doors and windows, can save you $2 per square foot in energy consumption. Homeowners can also claim up to $1,200 on exterior doors tax credit!
- Improved indoor air quality (IAQ). Beyond temperature control, energy-rated doors prevent pollutants and allergens from entering your home. These doors also have excellent moisture control, reducing the risk of mold.
What makes a door energy-efficient?
A door is considered energy-efficient if it has the ENERGY STAR certification.
ENERGY STAR is a government-backed program providing consumers with credible energy-efficiency standards set by the U.S. Environmental Protection Agency (EPA). This program incentivizes homeowners with tax credits and energy deductions when installing certified doors, windows, and skylights.
For a front door to be ENERGY-STAR certified, it must meet the following criteria:
- Manufactured by an ENERGY STAR partner
- Tested, certified, and verified by the National Fenestration Rating Council (NFRC)
- Carries NFRC ratings based on strict EPA guidelines
Key features of an energy-efficient door
Aside from energy certifications, energy-efficient entry doors possess the following features setting them apart from traditional door types:
1. Efficient insulating materials
Energy-rated doors have improved core construction and are made of tight-fit polyurethane foam insulation. This increases your door’s ability to block heat flow between your home and outdoors.
2. Low-E glass
Glass front doors have low emissivity (low-E) coating that minimizes ultraviolet and infrared light that passes through your door’s material. Low-E coatings reflect light and heat, keeping glass doors energy-efficient.
3. Multiple glazing
Aside from low-E coating, glass doors utilize multiple layers of glass with argon gas trapped in between. Known as ‘lazy gas’, argon slows down heat from passing through your door glass. Krypton gas is also used for multiple glazing with tighter gaps.
4. Tighter sealing system
Energy-efficient door frames feature magnetic strips, creating tighter seals around door edges. Brush-fin and fin-seal are also used for sliding glass doors to minimize heat loss and gain.
Additionally, modern doors are also equipped with adjustable thresholds to close any gap between your floor and the door.
5. Precise installation
Correct installation ensures a proper door seal and alignment for top-notch energy efficiency. Professional installation from a licensed contractor like Boelter Is Better to guarantee a polished and functional door for your home.

New doors also increase perceived value through added curb appeal, helping sellers find the best buyers fast and above the initial asking price.
Signs it’s time to replace your front door
Natural wear and tear will eventually damage even the most durable front door. Check for these signs to see if it’s time to get a replacement for your entry door:
1. Visible damage or wear
Look for cracks, splits, rust, pests, and warping that compromise your door’s structural integrity. Widespread damage makes your door’s insulation less efficient in blocking heat transfer, so it’s wiser to invest in a replacement soon.
2. Drafts and temperature changes
Does your home temperature still feel uncomfortable with the thermostat already cranked up? A poorly insulated door could be the culprit, as it allows drafts and air leakage to disrupt your home’s indoor air quality.
3. Difficulty opening or closing
Sticking and binding front doors are often due to warping and misalignment. While some causes of sticky doors are easy to fix, the constant struggle to open or close your door can lead to further damage and inconvenience if not replaced.
4. Moisture damage or rot
Wooden doors, especially composite types, are highly susceptible to water damage and mold growth. Over time, warping and rotting occur, indicating your front door requires a replacement.
5. Outdated style
Upgrading to a modern door after a major home improvement ensures your front entry matches the current architectural design. Old doors not only make your home look unattractive but also have outdated security features that could compromise safety.
6. Security concerns
Homes located in areas with high crime rates or have a history of break-ins should consider switching to new security doors. Modern entry doors feature smart locks, multi-point locking systems, fire-rated materials, and more to enhance your home’s security.
7. Increased noise level
Excessive outside noise entering your home is a sign of poor door insulation. Switching to a soundproofed front door will block noises and improve your home’s acoustics and comfort.
8. High energy bills
A leaky and drafty door could cause your HVAC system to overcompensate and consume more power than needed. Energy-efficient front doors would be a more cost-efficient solution than paying for skyrocketing utility bills.
9. Door frame or jamb problems
Sagging, warping, loose hinges, and splitting door jambs could stem from an ill-fitting door. Getting a new door with a compatible jamb will keep your door frame intact for years, reducing maintenance and repair costs.
10. Insect or pest infestation
Termites and other wood-boring insects can compromise the structural integrity of a wooden door. Tiny door gaps can also become the pathway for rodents and other critters to infest your home. Investing in a front door with a tight-fit seal and durable materials will prevent such infestation from recurring.
How to choose the best front door
Picking the best front door will give your home an entrance you can be proud of. There are a plethora of front door options in the market, and choosing the perfect fit is crucial for the best functionality and value for money.
To help you choose, below are the main aspects to consider when purchasing a new front door:
1. Energy rating
Various metrics measure front doors’ energy efficiency, including R-value, U-factor, VT, and SHGC rating. Here’s what they mean:
- R-value. R-value, or resistance value, refers to how well a certain insulation material can resist heat flow. Door R-values range from R-1 being the lowest and R-5 to R-7 being the recommended rating for superior energy efficiency.
- U-factor. U-factor or U-value measures the heat transfer rate through a door throughout its entire assembly. U-factor ranges from 0.35 to 1.1 or higher – the lower the U-factor, the better the door insulates.
- VT. Visible/visual transmittance OR VT is the amount of visible light that can pass through the door’s glass material compared to the total light that strikes its surface. VT values mean more light can pass through.
- SHGC. Solar Heat Gain Coefficient, or SHGC, measures the amount of solar radiation that enters a building through its door. SHGC values range from 0 to 1 – higher values are ideal for areas with colder climates and lower values for warmer climates.
2. Climate zoning
Front doors meant for Florida heat won’t work for Minnesota winters. To ensure your new front door suits local weather, you should check ENERGY STAR’s climate zone finder.
Under this climate zoning, the US is sub-divided into four zones:
- Northern Climate Zone. Areas under the Northern Zone have cold winters, including Minnesota and Alaska. Recommended front doors for these areas must have ≤0.20 U-factor and ≥0.40 SHGC rating for added solar heating during cold days.
- North-Central Climate Zone. Mid-Atlantic states from the lower Midwest and parts of California comprise the North-Central zone. These areas are warmer than the Northern zone, which will benefit the most from front doors with ≤0.20 U-factor and ≤0.40 SHGC rating.
- South-Central Climate Zone. Deep South states, including Texas and Oklahoma, cover most of the South-Central zone. These areas are hotter and more humid but can potentially experience cold winters on rare occasions. Recommended front doors for the South-Central zone must have ≤0.20 U-factor and ≤0.23 SHGC rating.
- Southern Climate Zone. As the smallest zone, the Southern zone includes areas near the Gulf Coast and entire Florida. These areas tend to be wet and humid, so look for doors with about ≤0.21 U-factor and ≤0.23 SHGC rating.
3. Design customization options
Energy-efficient front doors come with different customization options to enhance their aesthetics and functionality. Below are some of the customizations you can request from a reputable door installer near you:
Door finish options
Modern doors are available in a range of colors and textures to match the exterior of your home. You can opt for stained, glazed, or painted finishes, which are available in various colors.
Door glass options
Clear, decorative, and frosted privacy glass can be integrated into your door for additional lighting and style. These are available in multi-glazed options to maintain the door’s energy efficiency.
Panel styles
Choose from flat, arched, decorative moldings, shaker, and more styles for added visual appeal on your new front door. Most door panel styles are available with or without glass for a unique style that fits your home.
4. Budget considerations
New exterior doors cost $1,400+ on average, but you can find more affordable options for under $600. Highly customized front doors, on the other hand, can cost as much as $2,400 or more.
Here are average door prices based on popular types:
