Common Types of Windows
Awning |  |
Bay Window One type of window that is made up of three-plus smaller windows is a bay window. Generally, the center window will be paralell to the wall it protrudes from, while the outsides of the other windows will be tilted towards the wall. A bay window's constituent windows can be of any type. |  |
| A Bow Window is usually made of at least four windws that are arranged in a half-circle configuration, radiating from the wall of a building. |  |
Casement This type of window has hinged sides and will have a lower incidence of leakage. This is because the frame and the sash will press together closely and create a better seal. Windows like this will open outward and give a greater area for ventilation than sliding windows. |  |
Fixed Frame |  |
Single-Hung/Double Hung windows having sashes that move up and down. Among single-hung windows, only the bottum sash will move upward. You can create a ventilation area in a window of this type as large as half of the total glass area, and screens are easily installed. |  |
Skylights are placed in roofs and have the same angle as the roof they are on. They are usually positioned to receive as much sunlight as possible, which can bring more heat and light into your home. Realize that in the northern hemishphere, more sunlight comes from the north in the winter and the south in the summer. |  |
