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, cooler in summer.
Naperville and the Chicago Region has extreme changes in temperature between winter and summer. It gets very cold in winter then very hot in summer, 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.
