For a seamless transition from indoor to outdoor spaces, Panda Folding Doors are the perfect design choice. Also referred to as bi-fold or accordion doors, these innovative Folding Doors feature a proprietary top-hung design that allows individual panels to stack or “fold” against one another on either side or both sides of the door frame. When fully open, the stacked door panels provide a 90% unobstructed view of the outdoor space beyond.
