Sliding doors have one or more door panels that open by either gliding on a track or hanging from rollers mounted above. There are several types of sliding doors including multi-slide door, bi-fold door, barn door, pocket door, lift and slide door, and patio door, sometimes called a sliding glass door.
Unlike swinging doors, which require space to be set aside for the door panel to open, furniture and other household items can be placed near a slider. Exterior sliding doors typically feature large panels of unobstructed glass and are sometimes called panoramic doors. Massive openings can be achieved with sliding doors, which can open up a home and create a stronger connection to nature and the outdoors. Large openings are also perfect for high traffic areas like the passageway leading to a patio during a backyard get together.
