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, bi-fold, barn, pocket, lift and slide, and patio sometimes called a sliding glass door.
Unlike swinging doors, which require space to be set aside for the door panel (door) to open, sliders allow you to place furniture and other household items right beside them.
Exterior sliding doors typically feature large panels of clear glass. Sliding doors 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, deck, or outdoor recreation like a pool deck.
