Illinois Energy, Windows, and Siding, Inc., specializes in home improvements that help boost your home’s energy efficiency. In this blog, we’ll give you an overview of our products and services.

Making Your Home More Energy Efficient

Replacement Windows

— Our energy-efficient replacement windows are equipped with SmartGlass365 glass packages, which feature insulated glass assemblies separated by the Quadraseal™ spacer system. This system eliminates contact between interior and exterior surfaces, which reduces heat conduction. It also features low-emissivity coatings that selectively block UV and infrared rays. Combined with our insulated window frames, you can expect exceptional energy efficiency that results in energy savings.


— Here at Illinois Energy, we offer Cedar Ridge insulated siding, available in a wide selection of colors and styles. In addition to three different lap siding profiles, we also offer vertical lap siding that’s perfect for home styles with Barnhouse architecture. We also offer textured profiles, including shakes and scallions, options that feature a beautiful, natural-looking grain. All of our siding options require virtually no maintenance and, of course, provide excellent energy efficiency. You can also choose to have Tyvek® HomeWrap® installed under the siding for improved waterproofing and insulation.

Entry Doors

— Like our replacement windows, our CastleView entry door systems feature insulated glass, durable frames, low maintenance requirements and long life spans. We offer a wide variety of styles, colors and finishes that will work with any home style. In addition to entry doors, we also offer sliding vinyl patio doors.

Soffits and Gutter Systems

— Along with the above products, we also offer insulated soffits. As part of our Cedar Ridge line of products, our Stealth Vent soffits are a perfect match for our siding options. Insulated soffits help minimize the amount of hot air that would otherwise get trapped in the attic. When combined with an efficient ridge vent system, insulated soffits ensure proper attic ventilation and reduce potential damage caused by trapped heat and moisture. Additionally, we also offer low-maintenance seamless gutters that can be matched to your siding and soffits.
