  • Traditional bay windows with curtains Bay Windows for Bungalows

    Single-family bungalows are among the most common types of homes in the Chicago area. In a city of bungalows, all built with high-quality materials and craftsmanship but varying in sizes, colors, and levels, it can be difficult to stand out from the rest of the neighborhood. Bay windows can add a touch of exterior interest to what otherwise might be a plain or simple home.

  • Bay window with seating area Historic Window Replacement Take a stroll through Chicago and you won’t have to go far to find neighborhoods like Oak Park and River Forest where older architecture is predominant. But as buildings age, the quality of their windows can fade and the functionality may fail, detracting from the aesthetic appeal. You’ll want to upgrade these windows without compromising the style that attracted you to the home in the first place. Replacement windows can also help make your home more energy-efficient.
  • Bay windows in a kitchen with table and chair Kitchen Bay Windows

    Living rooms at the front of the house are no strangers to bay windows, offering a wide look out into the street. But that doesn’t have to be where your bay window lives. If you have the wall space and are looking to open up your kitchen, a bay window can let in more light and breathe new life into your kitchen. It can be as simple as a small bay window above the kitchen sink, inviting a glimpse of the outdoors as you prepare your meals each day.

  • Small bay window Fiberglass Windows

    Bay windows can provide a beautiful complement to your home, but the abundance of natural light and sense of increased space won’t mean much without long-lasting performance.

Help improve the energy-efficiency of your home with a low-maintenance set of windows that will look like new for years to come.

Replacing the bay window in your home presents an opportunity to add a personal touch to your living space. Consider customizing your bay window with grilles, hardware, or between-the-glass blinds or shades that are suited to your style and complement the style of your home. Operable windows flanking the large center pane of glass can also help capture the cool breezes that have earned Chicago the appropriate moniker of “The Windy City.”

Chicago Climate Recommendations


Residents of “The Windy City” live in a moderate climate with four distinct seasons — from cool, wet springs to mild, pleasant falls. The city’s close proximity to Lake Michigan tends to moderate temperatures in both the winter and summer, providing relief from the summer heat and limiting precipitation during the summer months. Conversely, the lake effect enhances winter precipitation, adding an extra layer of snow to go along with the often frigid temperatures.

Pella Impervia windows feature a durable powder-coat finish for the stylish look of painted wood. Pella’s wood windows  provide effective insulation to help keep your home warmer in the winter and cooler in the summer. Encompass by Pella® windows with maintenance-free vinyl frames also help mitigate the expansion or contraction that can occur when temperatures reach the height of extreme heat or drop to the level of severe cold.

Weather Protection

Double or Triple Pane Glass

Cut your energy costs with more panes of glass. Invest in energy-efficient double or triple pane windows that fill with insulating gas for added thermal efficiency.

Low-E Protection

Low-E Protection

Keep warm in the winter by reducing the heat loss from your home. Window panes of glass with Advanced Low-E will help keep your home insulated, blocking out the cold and keeping the heat in. 

Durable Materials

Durable Materials

Frequent storms during the winter bring bitter cold and frozen precipitation. Wood with aluminum cladding, vinyl, and fiberglass are low maintenance and can help stand up to extreme weather.
