A French door is a type of door that consists of two panels that swing open from the center. These doors are typically made of glass, allowing natural light to flow into a room while providing a view of the outdoors. They are often used as entryways to patios, gardens, or balconies, enhancing the aesthetic appeal of a home. French doors can be designed in various styles, including traditional and modern. They are commonly framed with wood or metal and can be customized with different finishes. Many homeowners choose French doors for their elegance and ability to create a seamless transition between indoor and outdoor spaces.
