This code lays down the standard procedures and practices for fixing various types of ceiling coverings, including the erection of timber or metal frameworks. It provides guidance on support spacing, fastening methods, and joint finishing for materials like gypsum, plywood, and fibre boards to ensure durable and aesthetically pleasing ceilings.

Practical Notes
Ensure timber frameworks are treated with preservatives against termites and dried to the specified moisture content before ceiling installation to prevent warping.
Always leave a slight gap at the perimeter walls to accommodate thermal and moisture expansion of the ceiling boards and prevent buckling.
Stagger the end joints of boards in adjacent rows to improve the rigidity of the ceiling plane.
