Slide-folding doors known also as folding sliding doors, accordion doors, or bi-folding doors can be made up of (2) two through (6) six door panel sections that are hinged together and are carried by an overhead track system. As the door slides open the panels fold up and stack in front of or against the wall. The panel that is closest to the wall can be supported by either by a pivot system or by hinges.
