Over the years, Illinois Energy Windows & Siding has installed thousands of windows all over Naperville and the Greater Chicagoland Area. Our window customers in Naperville, Illinois stretch from I-88 in the North, I-55 in the South, Route 53 in the East, and past Route 59 in the West. We have remodeled homes all over both the DuPage County and Will County areas of Naperville with new windows and siding installations. As members of the Naperville Area Chamber Of Commerce and sponsors of other Naperville community groups like KidsMatter2Us, Illinois Energy Windows & Siding is proud to be a part of the Naperville community. For over 15 years, we've been installing the highest quality windows all over the suburbs of Chicago, Illinois.

Energy efficient windows not only look great, but have superior performance to match.
You'll get the look you want and lower energy costs as well. We offer two types of windows – both offer exceptional quality and performance. Our energy efficient, no-maintenance, vinyl Worthington Windows and our energy efficient, Custom Shield Elite Wood Windows. Both brands of our windows incorporate the ultimate energy efficient and self-cleaning, SmartGlass365. SmartGlass365 uses the sun to stay cleaner, longer. A layer of Titanium Dioxide (TiO2) is activated by the sun’s UV rays to help organic matter on the glass surface to break down and decompose. When it rains, the organic matter is washed away across a layer of Silicon Dioxide (SiO2) that makes SmartGlass365 ultra-smooth. This innovative technology forces moisture to “sheet” off the glass, and dry faster and stay cleaner longer. Not to mention, you’ll have 99% less spots on the glass. What does all this mean? You'll spend less time cleaning windows – and more time enjoying life.

Comfort you’ll enjoy, 365 days a year. Stay warmer in winter, cooloer in summer.
Chicago has extreme changes in temperature between winter and summer. It gets very cold then very hot, so you need windows that can handle our extreme weather changes. SmartGlass365 has 3 metallic silver oxide coatings, that make up to 12 individual layers. This optimizes your home’s cooling system to keep you comfortable during summer. SmartGlass365 reflects the sun’s heat and keeps the inside of your house cooler. This provides the most superior Lo-E Glass performance & comfort while maximizing energy savings. Ultimately delivering a remarkable 96% better performance in summer energy efficiency compared to cheaper glass.

The mission of Illinois Energy is to enhance and enrich the lives of our customers, teammates and our communities by providing world-class remodeling products and services. We believe in tackling every day with an optimistic and positive attitude, life challenges become rewards instead of pitfalls.

We are incredibly proud of our partnerships with community organizations that share our optimistic approach to life. We would like to highlight one dynamic community group, KidsMatter, working to empower local youth and families. KidsMatter is empowering kids to realize endless possibilities. Youth and families are the future of our community. Yet every day, kids battle the stress of academic, social and economic competition. Left unmanaged, these stressors can undermine healthy personal development, and lead to chronic anxiety, depression, drug and alcohol use and other problems.
KidsMatter equips youth and families with tools to manage the stress of everyday life through dynamic school and community programs, practical education, resources and youth recognition. We harness the power of partnership with parents, educators and an extensive network of community resources to help kids and families thrive. Our goal: To stop problems in kids’ lives before they start!

When parents wonder what they can do to help their children become happy, competent, caring and responsible adults, KidsMatter offers answers. This is a commitment KidsMatter and Illinois Energy Windows and Siding share in for our community. Here is what IdaLynn Wenhold, Executive Director of KidsMatter, has to say about our community partnership. “One of our valued partnerships is with Illinois Energy Windows & Siding and their President Dave Sonner. They have sponsored KidsMatter’s Annual Job Fair for the past two years, which attracts over 1500 young people and serves to prepare them for the job market as well connect them with job opportunities. In addition, Illinois Energy Windows & Siding has supported the Naperville Youth Service Awards for the past three years, providing recognition for students who demonstrate excellence in service to their community. KidsMatter has truly been blessed by Illinois Energy Windows & Siding’s commitment to the health and well-being of youth and families.”

We cannot say enough good things about the impact KidsMatter has on our community. We encourage you to visit and become involved. Together we can empower our community, families and children to realize their endless possibilities.
