A folding door is a type of door that consists of multiple panels connected by hinges, allowing it to fold back against itself when opened. This design saves space and is often used in areas where traditional doors would be impractical, such as small rooms or closets. Folding doors can be made from various materials, including wood, metal, or glass, and are popular in both residential and commercial settings. These doors are commonly found in patios, balconies, and room dividers, providing flexibility in how spaces are used. They can be opened fully to create a wide passage or partially to allow for ventilation while maintaining privacy. Folding doors are also known for their aesthetic appeal, enhancing the overall look of a room or outdoor area.
