Bay Windows

Bay windows are popular for their aesthetic appeal both inside and outside of the home and for their ability to let in lots of natural light. This versatile style is popular in kitchens and living rooms, giving your home a clean look and increasing its value. Although initially prevalent in Victorian homes, updated styles can be easily incorporated into the design of modern houses. With an extended panoramic view, this style adds a touch of elegance and opens up a room, giving the impression of a larger living space. The area created inside is perfect for a reading or dining nook and the deep sill can be used to display plants or artwork. This style also provides excellent ventilation; with two operational sides, you can enjoy a nice outdoor breeze.

We are thrilled with the look and quality of our new door. After a minor rescheduling issue, the door was installed within a few hours. We were impressed by the professionalism, knowledge and willingness to please of everyone from our salesperson, to the measurer, the installation crew and customer service. My husband and I have already recommended Centennial to a number of our friends and neighbours, who all agree it is beautiful. Many thanks to you all.

Can I install a bay window in any room in my house?

Not only are these windows the perfect way to create a feeling of openness in a living space, they also add curb appeal to your home and can brighten dark spaces. When deciding if this style is right for a particular room in your home, start by consulting with a professional manufacturer and installer. There are several factors that need to be considered and they will be able to guide you through the process to make sure you are satisfied with your new product.

What is the difference between bay and bow windows?

Bay windows are constructed from three windows — usually a fixed style in the centre with operational ones on either side. With standard construction, they come together to form two 45⁰ angles. Bow windows are made of four or more windows — usually a combination of fixed and operational styles. They form a slight curve as they project away from the exterior wall of the home.

How big should a bay window be?

When determining the size, you must take into consideration the size of the opening and the projection — how far it will come out from the exterior wall. If you are thinking about installing a bay window where one does not currently exist, it’s a good idea to have a professional manufacturer and installer inspect the wall before you begin to provide a recommendation of size and installation technique.

Do bay windows have screens?

Any operational styles will have screens. Depending on the style that you choose, the screens will either be on the interior or exterior of the home. Bay windows with casement screens will be on the interior of the home and those with double hung screens will be on the exterior.
