A bulkhead is a section of ceiling that has been dropped and boxed-in or enclosed. Bulkheads are typically used to conceal something. It could be plumbing pipes, electrical wires, duct work, or exhaust fans.
A ceiling is an overhead interior surface that covers the upper limits of a room. It is not generally considered a structural element, but a finished surface concealing the underside of the roof structure or the floor of a story above.
Ceilings and bulkheads can be installed in a variety of different ways depending on their requirements or the design of the building structure.
The most common way to create a ceiling is simply applying plasterboard to the underside of a floor joist or roof truss joist.
Some buildings may require a services void between the underside of a floor joist and a ceiling finish, this is known as a suspended ceiling that will typically be constructed from lightweight metal sections that are suspended from the floor joists to the required depth of service void with a grid type construction of horizontal metal sections fixed to the suspended structs, these sections will support the plasterboard that is screwed to them from below.
Suspended ceilings are more commonly used in commercial buildings and buildings that have multiple dwellings.
It is important to understand the architect's specification for ceilings particularly for multiple dwelling constructions or individual dwellings with habitable space on three or more storeys as ceilings these instances will almost certainly be required to meet a fire rated specification of which would be expanded by the architect or fire officer.
