One of the best ways to improve your home’s energy efficiency is through your windows. To keep your home comfortable this winter, invest in this type of windows for your home. NEXT Door and Window shares with you the factors you should look for when buying energy-saving replacement windows in Illinois. The right combination of these four technologies makes your home naturally warm this winter:

Replacement Windows

Number of Panes

This refers to the number of glass sheets the window has. The idea is to fill the space between the panes with an insulating gas to minimize thermal transfer. With an optimal glass distance and right type of gas, most of the heat wouldn’t escape your home. We recommend double-paned windows for your next home improvement project. These windows in IL would suffice to help you achieve your desired indoor climate using less energy.

Gas Fill

The most popular insulating gas choices are argon and krypton. Both slow the movement of cool and warm air in the glass airspace, improving your home’s ability to retain its temperature. Together with other components, it creates a comfortable indoor environment all year long.

Frame Material

Other than the window glass, heat passes through the frame as well. Some materials conduct energy more than others do, which is why you have to choose the right one. At NEXT Door and Window, one of the frames we install is Ultrex®. Used in Infinity® and Integrity® from Marvin windows in Illinois, this pultruded fiberglass material insulates 500 times better than aluminum.

Low-E Coatings

Low-E, low emissivity, reflects a large amount of the sun’s undesirable rays, resulting in less heat loss through the glass. Manufacturers apply this microscopically thin layer to the interior side of insulated glass.

At NEXT Door and Window, we offer different windows with low-E technology, allowing you to control the heat gain. This way, you can naturally warm your home in winter and prevent it from overheating in summer.
