Types of Ceilings

Suspended Ceilings

A suspended ceiling comprises a metal grid system that is suspended from and below a slab or roof truss by either hangers or wires to a specified height above floor level. Lightweight panels are laid into the grid to create the ceiling. These are decorative and functional panels. The plenum is used to conceal services including wiring, air-conditioning ducts, plumbing, data and telecommunication services.

Flush Plastered Ceilings

This system is a seamless ceiling, comprising plasterboard screw fixed to a mild steel T –grid system. The entire ceiling then receives an application of finishing plaster to conceal all joins and abutments.

A moulded cornice is used to compliment the clean lines and is available in many profiles and sizes.

Nailed Ceilings

Commonly installed in residential units, plasterboard is fastened to a timber substructure and has an exposed jointing strip between panels.

Cornice is installed to the ceiling system and serves to enhance the room.


Bulkheads are used to create decorative features or to divide one ceiling system from another, emphasizing room divides.  When joining ceilings of different levels a bulkhead is installed to differentiate areas.


Bulkheads are purpose built and various construction methods are used, from prefabricated profiles to constructing in situ, similar to a drywall installation.
