HOW WINDOWS AFFECT YOUR HOME’S ENERGY EFFICIENCY

Your windows don’t actually consume or reduce energy by themselves, but they do still influence your home’s overall energy consumption. If you buy the right products, you’ll see that it’s faster to achieve your desired indoor climate while decreasing your energy use at the same time.

How Windows Affect Your Homes Energy Efficiency

As the premier source of Chesterfield doors and windows, Renewal by Andersen® of St. Louis wants to shed light on how windows affect your energy consumption at home. Here are some of them:

Heating and Cooling Your Home Naturally

Efficient windows heat your interiors in winter and keep them cool in summer. The secret lies in layers of spectrally selective Low-E coating, a technology that reflects certain rays of the sun. They keep the unpleasant ones out and let the desirable ones in.

In addition, double glazing boosts the insulating properties of your replacement windows in Chesterfield, MO. Inside the optimal width of air space between the two panes of glass, an argon gas blend significantly keeps the flow of heat transfer to a minimum.

Using a framing material that has an exceptional insulating value, you can expect your windows to prevent your indoor heat and conditioned air from escaping.

Using the Sun to Displace Artificial Lighting

When your windows promote plenty of daylighting, they help illuminate your interior spaces naturally. Apart from giving you wonderful outdoor views, daylight illumination reduces the need to switch on your lights. Otherwise, you might have to use artificial lighting to brighten your room even when the sun is up. In the process, you use electricity unnecessarily.

Minimizing Air Leaks

While most windows allow a hardly noticeable amount of air leakage, having a tight seal keeps them from being drafty. When the seal fails or the frame deteriorates and develop gaps, air infiltration gets out of control— and so does your energy consumption.

As the leading Chesterfield, Missouri, windows company, we custom build our products to weatherproof your home for a long period. We optimize our innovative technologies, including stainless steel spacers, dual sealing, and Fibrex® framing material to keep the chance of air leakage to a minimum. That said, many factors have to be considered to ensure your window replacement can boost your home’s energy performance to the fullest.

"Have nothing but great things to say about the window installation done today by John Hutchinson with Renewal by Andersen! He was friendly, personable and professional and did a great job installing. He did a great job of putting down roller pads and tarps with next to zero clean up. Would highly recommend them for any window replacement needed!"

"We had our new Renewal by Andersen windows installed on June 5th & 6th, 2025 and we LOVE them! The quality, beauty, and functionality are best-in-class! The whole experience from dinner presentation at Lazy River Grill, the initial in-home sales consultation and measurement, the regular communications from the salesman and concierge, and the installation team’s professionalism and skills made the process so seamless. This is the second home we have opted for Renewal windows and doors and have been delighted both times! Thank you Renewal by Andersen STL! "

"I had an excellent experience with RbA STL. Our designer, Courtney, was great and the finished product is awesome. The installation was easy and the gentlemen left our home cleaner than they found it upon entering. I would recommend RbA STL - you’ll get tired from their constant contacts, and that’s a GOOD thing!"
