Bay & Bow Windows

Bay & Bow Windows Installation

When one thinks of a bay window, images of a scary haunted house come to mind. But if you’re looking to renovate and upgrade your home you may wish to choose between a bay or bow window.
A bay window may be a good choice especially if your room is limited on space. The reason for this is that a bay window is built to project outward from an outside wall. The fact that it juts outward gives your room more interior space.

Upon first inspection, it may appear that bay and bow windows look very similar. However, there are some differences.

  • Bay Window has three openings, available in angled projections.
  • Bow Window will generally as a rule have four or five openings.

A bay window will have the main, focal picture window at its centrepiece, with two other smaller windows on either side laterally, left and right. Three openings with angled projections.

With a bow window, its structure is curved, which when viewed from the outside of the property presents a rounded appearance.

Both of these designs have an old-world, vintage aesthetic feel about them. Terms used to describe these windows are “four-lite bow” or a “five-lite bow.”

The fundamental design of a bay or bow window is that they are both built with an arc. Depending upon the number of windows that are used to construct each unit, the shape will slightly vary.

Typically being built using 3 windows, the bay window will have one casement window on each side, and one large main picture window positioned in the middle. While later establishing their mark in Victorian architectural design, bay windows have been around long since medieval times. As such, they are very stylish and most popular today.

Thanks to its front-and-centre picture window design, the bay window offers an unobstructed panoramic view of the outdoors. The two side windows panes are angled at 30 to 40 degrees to the centre of the picture window. A trademark design that always stands out as a main characteristic of the bay window is that the three windows aren’t typically the same size: the centre window is always the largest, with the lateral side windows being up to a quarter of the size of the primary main focal window. Install bay windows, they are perfect for hanging out to read a book, adding extra seating or just simply creating more space within your home. The cozy, comforting warmth you’ll feel makes coming home after a long day at work all the more enjoyable and welcoming.

While they may look alike, from a homeowner’s design perspective, both will do much to open up a room and give it space to “breathe”. With this appearance of additional space, more light will be let into the room making it pop with glamour and come to life with a welcoming warmth.

In a design sense, the angular lines and flat planes of today’s modern bay window are often considered more appropriate aesthetically for contemporary modern homes. Whereas the semi-circular outer structure of the bow window is ideal for any architecture style that smacks of the stoic Victorian confidence and elegance. Naturally, either type is perfectly acceptable for just about any style home. It all comes down to your own personal preference as the homeowner.

The bay window adds more interior floor space by protruding outward from the building’s main exterior wall space. Having more glass panes than bay windows, bow windows always allow more light to pass into the room seeing as they have more glass panes when compared to the bay window counterpart. The design of a bay window will only have three panels of glass and as such, they are rarely as wide as a bow window.

If you’re looking for something a little different away from the norm, a unique design is having the bow window wrap around the corner of the building. Utilizing this design element forms a unique turret shape on the outside corner wall and an enticing cozy nook on the inside. And with the right type of interior lighting, that cozy nook will look quite dramatic. And when viewed from the inside, a view from two sides of the home are allowed.

As a homeowner, you’ll have the versatility of options available to you.

    With a regular same-sized window opening, the cost of a bow window will run approximately 2.5 times more due to the fact that a bow window isn’t a single-window design. As such, the installation of a bow window will be more inherently complex. Often times, a custom-made shell will be constructed to fit with custom windows. Also, bow windows are more complex than a bay window installation. To properly seal out water and air, a bow window installation will require a soffit tie-in or a new hip roof.

    Homeowners have found that since the installation of their new bay or bow window more light comes into their home and seems to expand the space of the room where the bay/bow window was installed. In general, homeowners felt that it was a very affordable home enhancement.

    Make sure that the windows come energy efficient certified. Air leaks will have a costly impact on your utility bill. If installed correctly by qualified professionals, the windows will eventually pay for themselves in a few years in the amount of money you’ll save on your bill. You’ll be adding charm and beauty to your home and raising the value on your property. Looking good and saving money in the process is definitely a win situation.

    Grid Designs & Types


    Clear Glass

    Our double-paned windows with clear glass provide optimum noise protection compared to single pane glass. In terms of temperature resistance, it promotes the easy flow of hot and cold air from both inside and outside.

    Low-E Glass

    Low emissivity glass, or Low-E glass, is a strategic choice for lowering your home energy costs all-year-round. In winter, Low-E glass cuts down on heat loss by reducing radiant heat transfer and reflecting interior heat back into your room, where it needs to be. It also efficiently dispenses the sun’s rays—allowing more of them to enter the home as usable solar energy. This provides extra warmth while minimizing reliance on heating, which can account for up to 60% of a home’s energy costs.
    In summer the same principle applies but the effect is reversed. Low-E glass windows help reduce the flow of hot air into the cool interior. This specially formulated coating also reduces the effects of the sun’s ultraviolet (UV) rays, which are a leading cause of premature fading and degradation of fabrics and carpeting.

    Triple Pane Windows

    Triple-pane glass windows are the most energy-efficient models on the market. With the extra pane of glass, they moderate temperatures inside for optimal comfort in every season—during winter, cold air remains outside and warm air inside, while in summer the results are reversed.
    Special coatings are often applied to the glass to eliminate solar heat gain and boost its energy efficiency. The extra pane of glass truly provides a new level of insulation, airflow and energy efficiency.
