The purpose of a door closure is:
preventing passage of infiltration air; reducing air drafts and creating an enclosed space that can be heated or cooled more effectively (revolving doors are especially efficient for this purpose)
privacy, and noise reduction
keeping occupants inside a vehicle
regulation of access, especially when combined with various types of locks
for aesthetics (e.g. cupboard doors cutting off view of the contents)
to help prevent the spread of fire
