Folding patio doors consist of conjoined leaves that are fixed to an upper and lower track that allow each leaf to slide and neatly fold into the corner of the door frame. These folding door systems offer a clean method for modifying interior spaces or expanding an interior space into the outdoors.
Folding patio doors meet a broad range of architectural specifications. Available in numerous configurations, folding patio doors are able to alter interior room size to suit multiple functions and dramatically open interiors to exterior patios, verandas and panoramic views. By combining two door systems, a 90° zero post corner system opens the entire corner of a space providing views that are uninterrupted by a supporting wall or post.
