A casement is a type of window that is hinged on one side and opens outward, typically using a crank mechanism. This design allows for better ventilation and unobstructed views compared to traditional sliding windows. Casement windows are often made of materials like wood, vinyl, or aluminum, and they can be found in various styles to match different architectural designs. In addition to their functional benefits, casement windows can enhance the aesthetic appeal of a building. They are commonly used in residential homes and can be paired with other window types, such as double-hung windows, to create a cohesive look. Proper installation and maintenance are essential for ensuring their longevity and performance.
