Also known as fixed windows, are non-operable, meaning they can not be opened. This makes them offer enhanced security, energy efficiency and allows for larger sizes. This type of window can be assembled with or without a sash. With thin, low-profile frame, they are often used in areas where an unobstructed view is desired to maximize views and natural light.
