Fixed windows are non-operable windows that do not open or close. They are designed to provide natural light and views while maintaining energy efficiency. Fixed windows are often used in combination with operable windows to enhance the aesthetics of a building. These windows are typically made from materials like vinyl, aluminum, or wood and can come in various shapes and sizes. Because they do not have moving parts, fixed windows are generally more durable and require less maintenance than operable windows. They are commonly found in residential and commercial buildings.
