Gliding patio doors have one or more door panels that open by either gliding on a track or hanging from rollers mounted above. 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. 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.
