Louvered doors are used when privacy with natural ventilation and quietness for rest is desired, as they allow free passage of air even when closed. You can use louvered doors to help ventilate certain areas of your home, to add a small amount of privacy to otherwise open space, or as room dividers. Louvered doors are not much preferred because of dust. They are used for latrines and bathrooms of public buildings and residential buildings. These doors are used in cabinets, wardrobe, bathroom, utility rooms, etc.
