Which type of window is known for having a life attachment or hinge?

The correct answer is the casement window, which is characterized by its attachment or hinge on one side that allows it to swing open outward. This design enables the window to open fully and provides excellent ventilation, as well as an unobstructed view when open. The hinge mechanism allows the casement window to be easily operated with a crank or lever, providing an effective seal against the elements when closed.

Casement windows are often preferred for their energy efficiency and modern aesthetics, as the closing mechanism can create a tighter seal than other window types. Additionally, the outward-opening feature can be especially beneficial for homes with limited interior space or for areas where it might be safer to open the window outward rather than inward.

Understanding this design and operation is crucial when considering window options for a construction or renovation project, as it affects both functionality and energy efficiency in the home.
