Offering a Wide Range of Windows in Illinois

At Rooftop Designs, we offer a variety of options for new windows in Naperville and throughout Illinois to make your home look better than ever. Our sleek, clean designs can improve your house’s curb appeal, while addressing practical concerns as well. With our industry-leading vinyl choices, you’ll never have to paint your windows again, and these permanent products are even backed by a lifetime warranty. Vinyl windows are also easier to clean than traditional window designs, and do a better job of keeping out sound.

Most importantly, our cutting-edge window options can improve your house’s energy efficiency, reducing draftiness in your home and sealing in temperatures to help your HVAC system work better. A window’s U-factor, or U-value, typically ranges from 0.20 to 1.20. The lower this number is, the better the window will be at keeping the heat in. With our top-of-the-line triple-pane package, you can achieve a U-factor under a .20. These windows allow you to enjoy an almost immediate return on your investment and ongoing energy savings for years to come.

Rooftop Designs replaces and installs the following types of windows in Illinois:

  • Bay Windows: Our vinyl bay windows in Maryland are the ideal choice for homeowners looking to increase the exterior appeal of their property while also adding an increased sense of warmth and light to their house’s interior.
  • Bow Windows: Bow windows are similar to bay windows, except that they contain four or more sections, smoothly connected to form an outward curve. This allows you to get a panoramic view of the outside while improving the aesthetics inside your home.
  • Casement Windows: At Rooftop Designs, our vinyl casement windows can be installed as a single window, paired with another casement window, or input into a bay window structure. They are highly customizable, and a great choice for homeowners looking to upgrade their existing window designs.
  • Double-Hung Windows: Double-hung windows allow you to mix a classic design with innovative engineering. With a top sash that can be lowered and a bottom sash that can be raised, both window sashes can easily be locked in place for safety or removed in case of an emergency.
  • Garden & Awning Windows: Garden windows can bring dimension and light to your kitchen or any other room in your house. And with our awning garden window replacements hinge, you will be able to open your window at the top or bottom, making them ideal for basements, too.
  • Slider Windows: Our vinyl slider windows in Maryland are designed to maximize light when closed and increase ventilation when opened. With two panels that slide easily from side to side, these windows are the perfect choice for homeowners looking for extreme durability and improved energy efficiency.
  • Picture Windows: With a vinyl picture window from Rooftop Designs, you will be able to capture beautiful views in any room of your house, increasing light and visibility both inside and outside of your property.
