"casement" の定義と意味

What is a "casement"?

A casement is a type of window that is hinged on one side and opens outward, usually by turning a handle. This design allows for excellent ventilation and unobstructed views since the window can be fully opened. Casement windows are commonly used in both residential and commercial buildings. They are often preferred for their energy efficiency, as they create a tight seal when closed, helping to keep out drafts and maintain indoor temperatures. Casement windows can also be designed in different sizes and styles to complement the architecture of a building.
