A louvered door primarily consists of wooden fins, which are the angled slats that allow for ventilation while maintaining some level of privacy. These fins are typically arranged in a way that facilitates airflow, making them ideal for spaces where ventilation is needed, such as closets or utility rooms. The design of a louvered door helps to reduce direct light and provides visual separation without completely closing off the space.

Other materials such as glass panels, metal sheets, and plastic slats may be used in various types of doors, but they do not define the traditional louvered door. The characteristic wooden fins are essential for its function and aesthetic, emphasizing the importance of this component in both design and performance.
