What Are Bay Windows?

Bay windows are beautiful additions to any home or building. A feature of Victorian domestic architecture but adorning homes since the English Rennaissance, bay or bow windows give the gift of plentiful natural light and create the illusion of a larger space. Unlike flat windows, bay windows add more light to your interior and enrich your home's architectural style with a touch of elegance.

Bay windows describe any protruding window construction. A multi-panel window that projects outward the exterior wall of houses, this window style offers panoramic views and creates interior extra space that can be used as a window seat or storage space. This bonus space can also be used to display plants or decorative objects.

Bay windows vary widely in shapes and sizes and can be one or multiple stories tall. Most often, they take the shape of an isosceles trapezoid, typically referred to as canted bay windows, and rectangles. However, various other polygonal shapes can be used when designing modern bay window styles, including, although quite rare, triangles.

In addition to the large variety of shapes, bay windows also impress with the wide variety of colors available to the customer. Furthermore, modern windows can now be built from a wide range of materials, and this goes for bay windows too.

Why are our Bay Windows the best?

Due to the large variety of shape, style, material, and color options, it's only natural for customers to hire only window installers with a vast experience in the field of window installation. Given that bay windows protrude from the structure, it's imperative that the window installation process receives meticulous attention.

Our highly professional team will ensure your standard or custom bay window will be installed properly from the first try.

Bay Window Installation

Should I replace my Bay Windows?

Bay windows, just like any other style of windows, have a limited life expectancy. Regardless of the quality of the materials used or the workmanship behind their installation, there comes a time when bay windows need to be replaced. Here are a few of the most common signs that let you know you might need to consider replacement windows or at least have a professional check them:

  • Visible condensation within the panels of glass.
  • You are experiencing drafts.
  • There is mold or blistered paint around your window.
  • It is getting more difficult each time to open or close it, which means the frame may be warped.
  • You notice leaks and unwanted air circulation.
  • The hardware isn't working correctly.
  • The window clatters or clanks while opening.

If you've noticed at least one of these signs, your current window situation needs to change because your window is no longer ensuring maximum energy efficiency performance. In fact, it is most likely that you are losing money due to its deterioration.
Invest in new energy-efficient and high-quality windows and you will be able to save money in the long run. Chicago Window Guys provides you with the best team of professionals for any window replacement, installation, or maintenance project.
