Sliding doors are a type of door that opens by sliding along a track, rather than swinging open like traditional doors. They are commonly made of glass or lightweight materials, allowing for easy access and maximizing natural light in a space. Sliding doors are often used in homes, offices, and commercial buildings to connect indoor and outdoor areas. These doors can be found in various styles, including patio doors and wardrobe doors. They are popular for their space-saving design, as they do not require additional room to swing open. Sliding doors can also enhance the aesthetic appeal of a room while providing convenience.
