Fixed windows, also known as picture windows, are non-operable windows that do not open or close. They are designed to provide unobstructed views, natural light, and aesthetic appeal. They consist of a single pane of glass that is securely mounted within a frame. Unlike operable windows, fixed windows cannot be opened or closed for ventilation.
Fixed windows are known for their energy efficiency. Since they do not have moving parts or openings, they offer excellent insulation and reduce air leakage. Fixed windows can be designed with energy-efficient glass, such as low-E (low-emissivity) coatings and insulated glazing, to further enhance energy efficiency and thermal performance.
Fixed windows are often used to maximize views and bring in abundant natural light. Their large, uninterrupted glass surface allows for expansive views of the surrounding environment, making them popular for showcasing scenic landscapes or architectural features.
Fixed windows are structurally strong and can provide added stability to the building envelope. They can be used in combination with other operable windows or as part of architectural window arrangements to enhance the overall design and functionality of a space.
While fixed windows cannot be opened, they can be designed with safety glass options, such as tempered or laminated glass, to enhance security and safety. They are commonly used in areas where ventilation is not a primary concern, such as high-up or hard-to-reach locations, or in combination with operable windows to create a balanced window system. They offer architectural beauty, natural light, and energy efficiency, making them a popular choice in both residential and commercial applications.
