Which type of door is primarily utilized in residential occupancies to create smaller spaces?

Folding doors are designed specifically to divide larger areas into smaller, more manageable spaces, which is especially useful in residential settings. They consist of panels that can be folded back to open up a room or closed to create distinct areas, allowing for flexible room usage. This adaptability makes them ideal for situations where space needs to be reconfigured frequently, such as in homes that often host gatherings or family activities.

In contrast, revolving doors are mainly used for commercial buildings to facilitate the flow of foot traffic and minimize air exchange. Vertical doors may reference types such as overhead garage doors, which serve specific access functions rather than space partitioning. Glass doors are often used for aesthetic purposes and to allow natural light but do not provide the same flexibility in creating smaller spaces as folding doors do.
