👉 Louvered is a type of window pane, typically made of glass or aluminum, that has a curved opening at each end. These openings are usually used to allow light and air in during the day but can also be used to provide ventilation and control airflow during cooler weather conditions. Louvered windows are often found on older buildings or those with limited space for windows, as they offer an efficient way of controlling the amount of natural light that enters a room.
