Window features refer to the various components of a window, such as panes, frames, and hardware. Panes are the individual pieces of glass that make up a window, usually held together by a frame. They can be single or multiple, and can be used to create different shapes and sizes of windows. Window panes are often made of glass, but can also be made of other materials such as plastic or metal. Window frames are the structures that hold the panes in place and provide support for the window. Hardware includes the locks, handles, and hinges that are used to open and close the window. All of these components work together to provide a secure and attractive window.
