Plantation shutters (often called plantation blinds) are permanent, built-in window coverings featuring wide, horizontal louvers (slats) set into a solid frame.
Unlike regular blinds that pull up and down with a cord, plantation shutters open outward on hinges like small doors, and you manually tilt the thick slats to adjust light and privacy. They are typically made of wood or composite faux-wood, and because they are bolted directly into the window frame, they are considered a permanent upgrade to a home rather than a temporary window covering.
