Folding doors are a type of door that consists of multiple panels that fold back against each other when opened. They are often used to create a wide opening between two spaces, such as between a living room and a patio. This design allows for flexibility in how spaces are used and can enhance natural light and airflow. These doors are commonly made from materials like wood, aluminum, or vinyl, and can be customized to fit various architectural styles. Folding doors are popular in both residential and commercial settings, providing an attractive and functional solution for dividing or connecting areas.
