French doors are a type of door that consists of two panels, usually made of glass, which are hinged on either side. They open outward or inward, allowing for a wide entryway that connects indoor and outdoor spaces. This design not only enhances natural light but also provides a beautiful view of the surroundings. Typically used in homes to lead to patios, gardens, or balconies, French doors can be made from various materials, including wood, fiberglass, or aluminum. They are popular for their elegant appearance and versatility, making them a favored choice in both traditional and modern architecture.
