What Are Bay Windows?

A bay window is a set of multiple windows (typically three) which project outward from the main wall of the property. There are different bay window styles with the most common bay window shapes being a cluster of three, with a central picture window flanked by two smaller side panels creating a panoramic view.

The design can extend to the floor, creating extra internal space, or the bay window can be supported by brackets which create a ledge inside. The most popular form of side panels is double-hung or casement windows which open to allow added ventilation.

What’s The Difference Between a Bay and a Bow Window?

A typical bay window will have three sections that fit together at different angles while bow windows have four or five sections which are more rounded and produce a curved effect. However, there are some other key differences between them.

Bay windows typically feature a large picture window with two smaller ones on either side. With bow windows, all windows are the same size

Modern bay windows, with their angular lines and flat panes, are often better suited to modern homes. The semi-circular appearance of bow windows tends to be seen as a better option for more traditional architecture and period buildings.

As they protrude out farther from the wall, bay windows add slightly more space inside the property. However, bow windows tend to have more glass panes, so they let in more natural light. Bow windows can also be wrapped around the corner of a building, creating a nook on the inside and a turret shape on the outside. This provides a very desirable dual aspect view.

Can I Replace My Bow Window with a Bay Window?

Your bay window project may involve a replacement unit, so you’ll be focused on a new bay window cost. Alternatively, you may have existing bow windows and want to know whether installing bay windows is an option. The good news is that you can swap bay windows and bow windows if you want a new look.

Changing the style from a bow window to a bay window will give your home a fresh new appearance and update its style which you can augment with a change of colour and materials like wooden frames or aluminium frames. Additional building work may be required depending on individual specifications and building regulations, and this could increase the final price.

Do Bay Windows and Bow Windows Add Value to Your Property?

Bay and bow windows increase light levels, extend views of the outdoors and garden, and improve ventilation and airflow. They provide more internal space, and can also give your home that wow factor, creating a feature, and making it more appealing to prospective buyers. These are all things to consider when you’re researching double glazed bay window costs and want to compare prices.

The Benefits Of Bay And Bow Windows

Bay and bow windows are a popular choice for many homes, with numerous tangible benefits like better energy efficiency compared to a standard window, as well as an improved visual aesthetic. Average prices for bay and bow windows are higher, but the benefits are worth exploring and can justify these additional costs:

Style – any home with a bay or bow window will stand out, especially with more than one unit on the ground floor or matching windows on the upper floor. Choose classic circle bay windows or more contemporary box bay windows for modern properties.

More light – bay and bow windows provide a bigger window size, allowing more natural light into the room, making your home feel spacious and inviting.

Frame material – for new frames you can choose from uPVC frames or traditional timber for your new windows depending on budget and the type of property. Aluminium windows are becoming increasingly popular. Aluminium frames offer a contemporary feel to update a classic style window design for modern properties.

Different glazing options – up-to-date double or triple glazing will lower your energy bills by preventing heat loss. You can also consider noise-reducing glazing options in a busy location, and low maintenance glass which only requires occasional cleaning.

Extra space – these windows add more internal space by protruding outwards from the room. This can provide invaluable new floor area or create a feature like a window seat with integrated storage.

How Much Does a Double Glazed Bay Window Cost?

Average prices for double glazed bay windows mostly depend on the size of the window and how many sections they have; more panels mean a higher cost. Most bay windows have three sections, but they can have as many as five. Bay windows can consist of casement windows or sash windows, with the latter typically costing more.

Here are some standard sized window costs.

Cost Of Double Glazed Bow Windows

Like bay windows, the cost of bow windows depends principally on their size and the number of sections. For bay and bow windows with the same number of sections, you can expect to pay slightly more for a bow window because their installation is more complex.
