If you’ve ever felt a draft in the middle of winter or noticed your air conditioner working overtime in the summer, chances are your windows are partly to blame. Outdated, inefficient windows are one of the most common culprits behind rising utility bills and inconsistent indoor temperatures. A popular solution for many Maryland and Pennsylvania homeowners is upgrading to energy-efficient windows.

These windows are specifically designed to provide better insulation and protection. Our team at AC Matthews Roofing & Exteriors has helped homeowners and business owners across Maryland and Pennsylvania make the upgrade, transforming their homes and businesses while saving them money on their utility bills. 

But you may still be asking: Are energy-efficient windows truly worth the investment? Well, we are here to provide you with all the answers you need! Keep reading to learn how energy-efficient windows work, the top 5 benefits they provide for you and your home, and what signs indicate that it’s time for a window upgrade.

What Makes a Window Energy Efficient?

Unlike the single-pane windows still found in many older homes, energy-efficient windows provide superior insulation for your home. The effectiveness with which they insulate is what qualifies them as energy-efficient. One of the most commonly used standards for making this determination is the Energy Star standard. This standard outlines several requirements for a window to earn the certification, which include:

• Superior frame materials that aid in insulation
• Multiple glass panes with a specific amount of space between each pane
• Presence of specialized technologies, such as gases between panes and specialized glass coatings
• U-Factor and Solar Heat Gain Coefficient (SHGC) ratings

While any Energy Star certified window will have reliable performance, still pay attention to the individual U-Factor and SHGC ratings as they will be different across window models. The U-Factor rating indicates how well the window insulates, while the SHGC rating indicates how well the window blocks solar heat. For both ratings, the lower the number, the better!

The Technology Behind Energy-Efficient Windows

The technology built into energy-efficient windows is the result of modern-day innovation that has revolutionized window performance. Some of the most common technologies found in energy-efficient windows include:

• Multiple Panes: Instead of a single sheet of glass, energy-efficient windows use double- or triple-pane designs. Each layer of glass creates a barrier that slows down the transfer of heat and cold. The extra panes have the additional benefit of reducing outside noise, making your home quieter and more comfortable.

• Gas Fills: The space between window panes in energy-efficient windows isn’t left empty. This space is often filled with argon or krypton gas. These gases are denser than air, which makes them much better at slowing heat transfer. As a result, your home stays warmer in the winter and cooler in the summer, while your HVAC system doesn’t have to work as hard.

• Low-E Glass: Low-emissivity (Low-E) coatings are ultra-thin layers of metal oxide applied to the window’s glass. They reflect infrared heat while still allowing natural light to pass through. This helps keep indoor warmth from escaping during colder months and prevents unwanted heat from entering during hotter months. Low-E coatings also block harmful UV rays, protecting your furniture, flooring, and décor from fading.

• Strong Frames: The material around the window’s glass is just as important as the glass itself. Energy-efficient windows often use vinyl, fiberglass, or treated wood frames because these materials resist warping, swelling, and cracking. They also provide excellent insulation, reducing drafts and improving overall energy savings. With the right frame, energy-efficient windows can withstand a variety of harsh weather while maintaining their efficiency for decades.

Many of the windows we offer at AC Matthews include these features and more. We source from trusted manufacturers known for quality and long-lasting performance. So whether you’re looking for traditional styles, sleek modern designs, or custom fits, we can match you with the perfect windows for your home.

Top Five Benefits of Energy-Efficient Windows

Now that you understand what makes a window energy-efficient, let’s explore the top benefits that come with upgrading your windows!

• Lower Energy Bills

All of this technology may make it seem like energy-efficient windows are just going to cost you an arm and a leg, but the long-term savings they provide make them a smart investment. According to the U.S. Department of Energy, 25%–30% of household heating and cooling energy is lost through windows. By upgrading to energy-efficient models, you can substantially cut that loss.

With energy-efficient windows, you can enjoy:

• Noticeable decreases in monthly utility bills
• Less strain on HVAC systems and potentially fewer repairs
• Long-term energy savings that help offset installation costs

Our team has worked with many Maryland and Pennsylvania families who noticed immediate improvements after installation. 

• Reduced Drafts and Improved Indoor Comfort

If you’ve ever had to bundle up indoors because of drafty windows, you’ll appreciate the difference new energy-efficient windows make. Because of the superior materials used for both their frames and panes, these windows can block a significant amount of airflow. This results in a home that better maintains its indoor temperature without any drafts.

Here’s what homeowners typically notice:

• Fewer drafts and cold spots in winter
• A cooler home during hot summer days
• Consistent, stable indoor temperatures year-round

Drafty windows are a common reason people reach out about upgrading, and with good cause. So if you are having trouble with windows that don’t block airflow from the outside, reach out to AC Matthews today. We can walk you through the different window options we have and discuss what upgrading would look like for you.

• Protection From UV Damage

While sunlight can brighten up your home and give it an inviting feel, the UV rays that come with it can be tough on the interior of your home. Windows that use standard glass allow UV rays to pass through. This constant exposure leads to fading on carpets, furniture, and hardwood flooring. 

Energy-efficient windows solve this problem by providing UV protection through the use of low-E coatings or other films over the window’s glass. These overlays block UV rays while still allowing sunlight to pass through. Meaning you can enjoy natural light without worrying about damage to your home’s interior.

Key Benefits of UV Protection in Energy-Efficient Windows:

• Blocks harmful UV rays that cause fading and discoloration.
• Preserves the life of furniture, carpets, and flooring.
• Lets in natural light without the damaging effects of UV rays.
• Helps protect your health by reducing UV exposure.

• Increased Home Value and Curb Appeal

Beyond the comfort that energy-efficient windows provide, they also increase your home’s value. Buyers today are looking for homes that are well-protected, use minimal energy, and won’t require upgrades any time soon. Energy-efficient windows hit these marks and more.

Benefits for resale include:

• A fresh, modern look that enhances curb appeal
• Increased home efficiency & lower heating/cooling costs
• A strong return on investment compared to other upgrades

Even if you’re not planning to sell your home any time soon, investing in window upgrades that you know will add to your home’s equity is always a smart move. It is also beneficial if you decide to refinance down the road.

• Positive Environmental Impact

Choosing energy-efficient windows also contributes to a healthier planet. By reducing your household’s energy consumption, you help cut greenhouse gas emissions.

For eco-conscious homeowners, these windows mean:

• A smaller carbon footprint
• Alignment with sustainable living goals
• Even greater environmental benefits when paired with upgrades like insulated siding or reflective roofing systems

Our team regularly helps homeowners create whole-home efficiency plans that include energy-efficient windows along with roofing and siding improvements—all designed to minimize environmental impact.

When to Replace Your Windows

You may already be sold on the idea of upgrading to energy-efficient windows, or maybe you’re waiting until your current windows are no longer performing well. But knowing when your windows need to be replaced isn’t always easy. Here are a few signs that indicate that it’s time for an upgrade:

• Persistent drafts, even when windows are closed
• Windows that stick or won’t close properly
