What type of window consists of overlapping sections of tempered glass held in a metal frame?

The type of window that consists of overlapping sections of tempered glass held in a metal frame is known as a jalousie window. Jalousie windows are characterized by their use of parallel slats of glass or acrylic that can be adjusted individually to control ventilation while still allowing light to enter. The slats are usually held together by a frame and can be opened or closed using a lever or crank mechanism, providing flexibility in airflow and privacy.

This design allows for excellent ventilation, even in inclement weather, as the slats keep water out while allowing air to flow freely. The use of tempered glass enhances durability and safety, making jalousie windows a popular choice in many building designs, especially in warmer climates where airflow is a priority.

Other window types mentioned serve different functions. Casement windows are hinged on the side and open outward, sash windows consist of one or more movable panels that slide vertically or horizontally, and slider windows move from side to side. Each serves unique purposes, but they do not feature the overlapping slats characteristic of jalousie windows.
