Sliding doors and folding doors are common types of indoor doors, and their difference lies in their opening method and construction.






Sliding doors usually consist of two or more door panels, which are installed on tracks and can slide open and close along the tracks. Sliding doors usually require a relatively long wall space for installation, as the door panel needs to slide on the track. They are usually used for larger entrances, such as those connecting the living room and terrace, or for separating rooms.






Folding doors typically consist of multiple door panels, which are hinged together and can be folded to open and close. Folding doors usually require relatively short wall space for installation, as the door panels can be folded up. They are usually used for smaller entrances, such as those connecting kitchens and restaurants, or for separating small spaces such as storage rooms or laundry rooms.






Therefore, the main difference between sliding doors and folding doors lies in their opening method and applicable scenarios. Sliding doors are suitable for larger doorways and require longer wall space for installation, while folding doors are suitable for smaller doorways and require shorter wall space for installation.
