What does a "projecting" window refer to in terms of its movement?

A "projecting" window is designed to swing outward. This type of window typically has hinges on one side, allowing the entire sash to pivot away from the building. This outward movement creates an opening that can improve ventilation and potentially enhance views. Projecting windows are often found in residential and commercial buildings, as they facilitate fresh air influx while providing ease of cleaning.

Understanding the mechanics of different window types is important in firefighting operations, particularly regarding egress and ventilation strategies. For example, when dealing with a fire situation, knowing that a projecting window swings outward can aid firefighters in planning effective access and utilizing the window as a potential entry or exit point during rescue operations.
