Fensterflügel

Fensterflügel, often translated as "window sash" or "casement," refers to the movable part of a window. It is the frame that holds the glass and swings open or slides to allow for ventilation or access. Fensterflügel are typically hinged on one side, allowing them to open outwards or inwards like a door, or they can be designed to slide horizontally or vertically.

The design and material of a Fensterflügel can vary significantly. Historically, they were made from wood, but modern windows often feature frames made from uPVC, aluminum, or composite materials, each offering different advantages in terms of insulation, durability, and maintenance. The type of Fensterflügel used can impact a window's energy efficiency, security, and aesthetic appeal.

Different types of Fensterflügel exist to suit various architectural styles and functional requirements. Casement windows, where the sash opens outward on hinges, are common. Awning windows have hinges at the top and open outward from the bottom. Hopper windows are similar but hinge at the bottom and open inward. Sliding windows have sashes that move horizontally along a track. Tilt-and-turn windows offer dual functionality, allowing them to tilt inwards from the top or swing open fully. The choice of Fensterflügel affects how a window can be operated and its overall performance.
