Casements are a type of window that is hinged on one side, allowing them to open outward like a door. They are typically made of wood, vinyl, or aluminum and can be designed in various styles to fit different architectural aesthetics. Casement windows are popular for their ability to provide excellent ventilation and unobstructed views. These windows are often operated using a crank mechanism, making them easy to open and close. Casements can be found in both residential and commercial buildings, and they are known for their energy efficiency when properly sealed. They can also enhance the overall appearance of a structure, adding charm and character.
