"window furniture" refers to the various hardware components and accessories that are attached to or associated with windows to enhance their functionality, security, and aesthetics.

This can include:

1. Handles and Cranks: Used for opening and closing windows. These can be simple lever handles or more complex cranking mechanisms, depending on the window type.

2. Locks and Latches: Essential for security, these components ensure that windows can be securely closed and locked.

3. Hinges: Allow windows to pivot open or closed. The type of hinge used can vary based on the window design, such as casement or awning windows.

4. Stays and Restrictors: These are used to hold windows open at a certain angle or to restrict how far they can open, which is important for safety and ventilation control.

5. Seals and Weatherstripping: Although not always classified strictly as "furniture," these components are crucial for ensuring windows are weather-tight and energy-efficient.

6. Screens and Grilles: Often considered part of window furniture, these provide additional functionality such as insect protection or security.

7. Decorative Elements: Includes any aesthetic additions like trims or moldings that enhance the visual appeal of the window.

In commercial construction, the selection of window furniture is influenced by factors such as building codes, safety standards, architectural style, and the specific functional requirements of the building.
