Waterloo Bay Windows

Bay windows maximize available light and space

Bay windows are a popular addition to homes in the Midwest because they allow more light into the home and also create space by extending past the exterior wall. Northeast Iowa may be known for its farmland, but it’s also home to some beautiful scenery year-round with lush sunny summers and postcard-worthy sparkly snow in the winter. A bay window invites in more sunlight and creates a cozy nook that can be used in a number of different ways.

Bay windows are popular additions to existing homes in order to create more space within a room and they are also commonly used in new construction of varying styles including contemporary homes as well as traditional styling.

Commonly known as: box bay window, square bay window, casement bay window

  • Bay Sizes Bay Windows Sizes

    Bay windows are available in many sizes, from small bay windows that measure around 40 inches wide to much bigger. Large bay windows can add additional light and create the illusion of additional space, making them a popular choice for homes with limited square footage. A large bay window is a nice addition in a dining room with limited floor space because it gives a little extra wiggle room for maneuvering around chairs when seating guests.

  • Bay window with bench seat Bay Window Seats and Benches Bay windows protrude outward, opening additional space inside your home. You can take advantage of the extra square footage to add more seating to your room. Bay window seats and benches are popular options for making a comfy nook. Built-in window benches with storage under the seat are a practical use of space, creating extra seating as well as a place to stow essentials like table linens, blankets, or even board games.
  • Bay windows in a kitchen with table and chair Kitchen Bay Windows

    Bay windows maximize the light in the home, which can be a welcome feature during short winter days. Adding a small bay window in your kitchen can make it feel bigger and brighter. The bay window shelf creates additional space for displaying picture frames or holding practical essentials like candles or cookbooks. In a kitchen, a bay window shelf makes a great spot for housing a small herb garden, which is both a useful and beautiful accent.

  • Small bay window Bay Window Options

    Bay windows that open are a great way to let in cross-breezes during the mild spring and fall months in Iowa. The most common bay windows that open are created with a large fixed window in the center along with flanking casement windows on either side. The opening sides of a bay window can also be created using double-hung windows. Bay windows come in a number of options for material — but vinyl is one of the most popular options for Iowa due to its low-maintenance nature. Fiberglass is another popular option, known for its ability to withstand extreme temperatures.

The climate in the Cedar Valley includes large seasonal temperature differences encompassing severely cold winters, blistering hot summers, and wet springs. Average rainfall in Waterloo is around 35 inches, and average snowfall is similar — around 34 inches. Vinyl and fiberglass both offer superior weather resistance with low-maintenance requirements.
