Bay Window Prices

Bay windows are defined as windows that project outward of the main walls. The name is so because it forms a bay inside the house. Bay can be defined as a space or void in the wall window between window frames or doorway between door frames.

Bay WindowsBay windows differ in size – from an average-sized window that starts a little below the head height or a large one that runs from ceiling to floor (full bay). The latter obstructs the regular floor shape, which may be a more costly installation because of its odd-shaped floor plan. They are commonly installed (with window seats) in front of breathtaking scenery. Designs range from extravagant antique and Victorian architecture to sleek modern lines. They are seen on mansions of the early English Renaissance.

Bay windows are usually made of three parts a picture window is flanked by smaller windows on both sides at a particular angle although the number of window parts depends on the homeowner. Because of their size, bay windows ultimately bring light into a room. Double-hung windows or casement windows can be used to provide proper ventilation. Bay windows not only provide space but also enough light from many angles, especially tall ones.

Bay windows may range from 3-feet to 6-feet in width or in height. When replacing normal windows, it is cheaper to install bay windows of the same size as the previous ones.

Bay Window Materials


Different materials can also be used to manufacture the frames of your ideal bay windows. You just have to consider the maintenance and look of the window when choosing. Double or triple panes may be ideal for bay windows, depending on your needs. Argon gas-filled panes will help in energy conservation by slower heat conduction/convection. Because of its size, a bay window should be well-supported. Use braces or steel cables; ask the manufacturer to install them for you although they can be purchased separately.
