Spring into savings: the benefits of window replacement for your home

If the spring season gets you excited to spruce up your home, then it’s the perfect time of year to consider window replacement. Not only can new windows give the exterior of your home a boost in curb appeal, but they can also improve your home’s energy efficiency. The more energy efficient your home is, the lower your energy bill. In fact, when single-pane windows are replaced with ENERGY STAR® rated windows, households see an average drop in their energy bill of 13%! That can really add up over a year. Plus, with more or improved natural light, it’ll feel like the interior of your home got a little beauty boost, too. So, let’s explore different energy efficient windows, materials and a few energy-focused features that can transform your home.

Types of energy efficient windows: Double-pane vs. triple-pane

Double-pane and triple-pane refer to the number of panes of glass in a window. So, double-pane windows have two panes of glass and triple-pane windows have three layers of glass. In between each layer, there is often argon gas, which provides a kind of insulation, creating more indoor comfort while taking some of the load off your heating and cooling system.

Today’s windows have come a long way, and double-pane windows are now the norm. So, while triple-pane windows are more expensive and may not be in your budget, that’s ok. You’re still going to get that added energy efficiency with double-pane options. 

You can also use different pane windows in different areas of your home. For instance, triple-pane windows are going to provide better temperature control in north- or east-facing rooms. They’re also a superior choice in more extreme climates (high heat and/or frigid temps) because of their ability to decrease thermal transfer. Another benefit of triple-pane windows that might be worth the extra investment to you is their increased ability to reduce sound compared to double-pane windows.

Window feature options to improve energy efficiency

Once you’ve decided if you’re going with double-pane or triple-pane windows, then you get into some of the really fun stuff — the energy-saving features! Here are some options to consider.

ENERGY STAR certified

Look for the blue ENERGY STAR label or ask your window replacement consultant about their ENERGY STAR certified products. All ENERGY STAR products have been independently certified and verified to perform at levels that meet or exceed energy efficiency guidelines set by the U.S. Environmental Protection Agency. Not only that, ENERGY STAR also provides information on the best products for your climate zone. (Find your climate zone here.)

Low-e coating

If you’ve ever felt the blazing sun heat up a room through a nearby window, then you’ll appreciate the effects of a low-e (short for low emissivity) coating. This type of thin glass coating minimizes heat transfer by reflecting infrared heat, which keeps your home cooler in the summer and warmer in the winter. 

Gas fills

We mentioned earlier that double-pane and triple-pane windows often contain argon gas in the space between the panes. You might also see krypton used. Both types of gas fills improve insulation and reduce heat transfer.

Warm edge spacers 

The seams — or edges — where multiple panes of glass meet are notorious spots for air to easily enter or escape. A warm edge spacer, however, is designed to fit in the area where edges meet in order to reduce heat flow and condensation, improving energy efficiency and preventing mold buildup.

Choose the right window materials for durability and energy efficiency

Now that we’ve covered some important features of energy efficient windows, let’s take a look at window frames.

Vinyl windows

Vinyl windows are a great high-quality, affordable option. If you’re on a budget, go with vinyl. Not only are they low maintenance, but they’re also resistant to warping, fading and cracking, which is going to help you save money in the long run. Plus, they’ll give you an added energy efficiency boost because vinyl is a strong insulator.

Fiberglass windows

Fiberglass windows will definitely set you back more cost-wise than vinyl windows, but they’re also going to provide a more polished look with a healthy dose of added strength. Those extreme climates we mentioned earlier? Fiberglass is the go-to choice there (though it can be used anywhere). Because fiberglass window frames experience almost zero expansion or contraction, there is less risk for seals to fail, improving overall energy efficiency.

Wood windows

If you’re looking for the ultimate customization and aesthetic lift, look no further than wood windows. Also energy efficient and durable, the main draw to wood windows is in their design. You’ll find aluminum elements on the exterior to protect your home and windows from weather, rot and corrosion. But on the inside, go wild making all your interior design dreams come true!

Increase natural light without increasing the temperature

New windows allow you to maximize natural light penetration into your home. Whether you’re in the market for picture windows, bay windows or even sliding glass doors, the increased natural light can totally transform the look and feel of a room. And, as mentioned earlier, window glass technology and materials have advanced so much that adding more natural light doesn’t mean adding more heat from the sun. If you’re feeling extra daring, ENERGY STAR also offers energy efficient skylights.

Keep your home’s curb appeal top-notch

It’s no surprise that spring is the most popular time of year for people to buy and sell homes. New windows are a big plus for potential buyers because of the financial savings that accompany their energy efficiency. Even if there are no moves in sight, window replacement is a great way to increase the value of your home while also lowering your energy bill and reducing your carbon footprint.
