About Bow Windows

Bow windows are elegant feats of architecture and design that extend out from the home and create expansive views. They consist of four or five windows that create the curved shape of the bow window. Bow windows are typically made up of casement windows, which open outward. Casements open using a crank mechanism, which makes them extremely easy to operate. The crank is controlled by using a fold down handle that glides the window open and closed, and holds it open even in the presence of wind. Bow windows differ from bay windows, which are typically composed of three windows and form a hexagonal angle rather than a curved shape.

Pros and Cons

  • Bow windows let in more natural light than many other types of windows.
  • Bow windows have a lot of curb appeal and high return on investment.
  • Bow windows can be installed in a variety of ways.
  • They even have the ability to wrap around the corner of a home and give two different views.

  • Bow windows can be expensive.
  • They are not only larger than most other windows, but are also labor intensive to install and specifically designed for each home.

Locating Bow Windows in Your Home

Bow windows are the focal point of any room they are found in, bringing in lots of natural light, increasing air circulation, and presenting large unobstructed views. Bow windows can be put in the front rooms of a home for curb appeal, or in bedrooms and other less noticeable areas to bring interest to other exterior areas of the homes. Bow windows are often accompanied by window seats on the inside.

Glass Types

Most windows are double pane (with two layers of glass), but can be upgraded to triple pane for increased energy efficiency. This upgrade initially makes for a more expensive window, but over time lowers energy bills. Regardless of how many panes you choose, bow windows can also come with tempered glass and insulated glass upgrades as well. Tempered glass is stronger and can handle impact better than non-tempered glass. Insulated glass contributes to energy efficiency and can retain heat better than non-insulated glass.

Frame Materials

Bow windows are commonly manufactured in vinyl, wood, as well as composite fiberglass materials, depending on the brand. Vinyl windows are on the less expensive side of the price spectrum, whereas wood and composite frames will be more expensive. Wood and composite frames are stronger than vinyl, but if you compare longevity and upkeep of materials vinyl and composite will not deteriorate due to weathering as quickly as wood. If your priority is weatherproofing even the most extreme conditions and achieving high energy efficiency, explore the unique fiberglass offerings from each manufacturer. If you want a statement piece, wood windows are an effective choice that also hold value in sturdiness. The material you choose for your bow window will depend on your budget and style preferences. Brands differ substantially in the colors, grids, and other features offered, so the material you choose will depend on the design options you are looking for.

Bow Windows Replacement Pricing

The price of bow windows can vary by brand, frame material and additional features, but a general price range is between $5,000 and $7,000.
