Fixed windows, also known as picture windows or stationary windows, are a type of window that cannot be opened or closed. Unlike operable windows such as casement, sliding, or awning windows, fixed windows are designed to remain in a fixed position and are not intended for ventilation or access.
The main purpose of fixed windows is to provide unobstructed views, maximize natural light, and enhance the aesthetic appeal of a building. They consist of a single pane of glass that is often large and expansive, allowing for expansive views of the surrounding environment. Fixed windows are commonly used in areas where ventilation is not a primary concern, such as in combination with operable windows in a window configuration or in locations where additional natural light is desired.
