A wall is a usually solid structure that defines and sometimes protects an area. Most commonly, a wall separates space in buildings into rooms, or protects or delineates a space in the open air. There are three principal types of structural walls: building walls, exterior boundary walls, and retaining walls.
Building walls have two main purposes: to support roofs and ceilings, and to divide space, providing security against intrusion and weather. Such walls most often have three or more separate components. In today's construction, a building wall will usually have the structural elements (such as 2×4 studs in a house wall), insulation, and finish elements, or surface (such as drywall or panelling). In addition, the wall may house various types of electrical wiring or plumbing. Electrical outlets are usually mounted in walls. Building walls frequently become works of art, such as when murals are painted on them.
On a ship, the walls separating compartments are termed 'Bulkheads', whilst the thinner walls separating cabins are termed 'Partitions'.
