What materials are used in jalousie windows?

Jalousie windows are recognized for their unique design, which features adjustable slats that can be opened or closed to control ventilation and light. The correct choice refers to a metal frame that holds adjustable sections of tempered glass, which is particularly suitable for this type of window because tempered glass is both strong and safe. It resists shattering, which is important in a window system that is frequently adjusted.

The metal frame provides durability and support, allowing for the efficient operation of the adjustable sections. This combination of materials is essential for jalousie windows, as it enables them to function effectively while maintaining structural integrity over time. The choice of tempered glass further enhances safety by minimizing the risk of injury in case of breakage, as it tends to crumble into small, less harmful pieces.

Other materials like wood, plastic, fiberglass, or concrete do not align with the standard construction details and functionalities expected from jalousie windows, which is why they do not fit the characteristics that make the chosen answer correct.
