Qualities such as size, thickness, color, material and type affect the way the interior door works and looks in a room. Several interior doors operate differently based on their mechanical configurations, though they all feature some basic articles of hardware to allow them to fit carefully within the doorway.
Hinged doors are the most common interior door in a home, and they are designed to open either inward or outward on the right- or left-hand side. Some swinging doors may open both ways, and double-door configurations feature two doors put together to allow a larger degree of entry into a bigger room, though two doors set together are frequently used for outside entrances leading into the home.
Folding doors are another type of interior door, and they are frequently installed to save space and allow easier access into smaller rooms. They are typically used when a swinging door's movement would otherwise be restricted, but many homeowners also choose to purchase these doors for their appearance and stylistic elements.
