Slats and slots are two types of window coverings that can be used to control light and ventilation. Slats are thin pieces of wood or metal that are placed across a window opening and allow light to pass through, while slots are wider openings that allow air to flow through.
Slats generally have a more open look, while slots create a more closed-in appearance.
Slats have the advantage of being able to increase airflow through the window, which can help reduce the amount of heat and humidity that builds up in a room. Slots, on the other hand, can be used to block out light and restrict airflow, which can help keep a room cooler in summertime and warmer in wintertime.
Overall, slats are generally preferred over slots because they provide a more open view and allow more air circulation. However, slots can be useful in specific situations where air circulation is desired or where light is blocked.
