Bay Windows: What are they and how much do they cost?
While we tend to think of windows as structures that let light in and bay windows are capable of so much more than that. They are built to change the exterior appearance of a building for the better and increase the surface area of a room.
Let’s find out a little more about bay windows, the common styles, features, and more.
What Are Bay Windows?
As the name suggests, a bay window projects outward from the exterior walls of a building and forms a bay in the room. This term is used for all protruding windows, regardless of height.
They are all square or polygonal, with the most common inside angles being 90, 135 or 150 degrees, but you may also see triangular bays at 120 degrees. There are many ways to manufacture bay windows today but most of these involve setting three or more panes of glass into a shape that characterizes the style.
The different options can be described as:
This type would where the bay is fitted to a normal aperture, where the bay is only the same width and height as the actual window opening – much like replacing a flat plane casement window with one that is “3D”.
Best described as where the bay is part of the house walls and would be floor to ceiling height in most cases. This type of bay can even extent to the full height of the house, right up to the roofline. Many period “bay-fronted” homes are of this type.
Boxed Bay Windows:
They are shaped like a box, typically rectangular, with flat sides and front. It’s very common in Europe, and you may also know it as a canted window. This style is viewed as the “real” bay because of its three-sided configuration.
Bowing Bay Windows:
Very popular in 18th century England, bow windows are based on curves. They’re normally made using regular flat glass panes within a number of window frame segments, and require at least four or five segments of panes to create a nicely curved bay.
Circle Bay Windows:
Very similar to bow windows, the Circle Bay Window features a semi-circular appearance (can also use curved glass panes), but the the curve is a lot more prominent. Circle bay windows are often embellished with decorations and bring a lot of natural light into the room.
Functionality of Bay Window designs.
The way the actual windows function within the bay itself is going to depend upon the style, primarily you will see either casement of sash designs used within the bay.
Casement windows will open outwards from side hinges, sash windows will slide up & down within the frame, but you could also opt for awning casements if you prefer that type of bottom opening style.
Of course you could opt to have fixed windows, in which case none of them will open. A lot of period homes built with integral bays were originally fitted with sash windows.
What Are the Advantages of Bay Windows?
They are quite dramatic additions to a home, so the first benefit is obviously related to the improvement you’ll bring to the architectural appearance. The very fact that they extend outwards from the property increases the view, and therefore even a small example will offer excellent views of the outdoors, which you can see from many different angles.
Bay windows come in various sizes and shapes, and are made of most materials already used in the making of windows and doors, such as aluminium, wood or uPVC.
When it comes to colours, you will often get to pick both interior and exterior colour, which can be different. You may choose natural colours or wood-like designs or even go for bolder colours.
For the glass designs, you get to choose from acrylic block, leaded, laminated, tempered, obscure, or impact. There are also different pattern grid options such as colonial, diamond, prairie or double prairie.
Bay windows also provide abundant natural light, being a way better option than standard flat-plane windows.
Another great benefit of bay windows is that you can create extra space within the house. This way, you’ll get an additional seating or storage area.
Install a window seat as a place to enjoy your reading or a set of shelves to increase storage area. There are many interior design ideas you can apply to the new space provided by these windows.
What Are the Disadvantages of Bay Windows?
The most obvious disadvantage of having a bay window is the difficulty in building and installing one “from scratch”. If you don’t have the basic structure in place to fit a bay, then it can be time consuming, and quite costly to build it.
Another thing to consider before buying a bay window the actual composition of the windows themselves. Choose only quality structures even if they are pricier. Low-budget options can come with structural problems that cause the window to distort, creak and even leak over time.
In general, they will cost more than most other window designs.
How much do Bay Windows cost?
With so many design and material options available to, the price of bay windows varies greatly. Depending on what the frame is made of, and the type of glazing used, you can expect to pay anywhere from £2,000 to £8,000 for a new bay window fitted.
We should note that uPVC windows are cheaper than timber and aluminium windows, so they’re a better option for people on a budget. Below are a range of prices in the current market – fitting costs are very variable, so the best thing to do is to get 3 or 4 quotes from independent suppliers to give you an accurate assessment of what the work will cost for your home.
