Homeowners In Thornton Benefit From Our Energy-Efficient Windows

In Thornton, Colorado, temperatures in the winter average 22 degrees at night, and in the summer, 88 degrees during the daytime. But with energy-efficient windows, homeowners can keep their homes comfortable all year. And best of all, you’ll see a reduction in your energy bills. 

We also know that people in Thornton love the environment. Energy-efficient windows make it so your furnace or AC doesn’t have to run as often, reducing your carbon footprint. Our replacement windows can also add resale value to your home.

Double-Pane Windows Are Superior to Single-Pane

Windows provide both aesthetic and functional purposes. They allow in natural light to let the best parts of the outdoors in while keeping the unwanted elements out.

There is a major difference between double-pane and singl-pane windows. Single-pane windows don’t provide as much structure or durability and are easily stressed by environmental factors. They also don’t filter out as much infrared light.

Perhaps you’ve entered a home with single-pane windows during a hot summer afternoon and noticed how quickly the sun heats the room to unbearable levels. And if the sun is shining brightly, the infrared rays make the room even hotter. 

At Clearwater Exteriors, we offer double-pane windows to filter out more of the sun’s heat and infrared light, maintaining a comfortable temperature throughout your home.
