Gyprock Supaceil plasterboard for ceilings

Gyprock Supaceilsuptrade

Gyprock Supaceil is the first plasterboard in Australia to feature Optimised Core technology.

Supaceil is part of Gyprock’s Residential Select range of premium quality plasterboards. It is specifically designed for use on internal ceiling linings - predominantly in residential applications - where no specific fire, acoustic or moisture resistant requirements are specified.

Gyprock Supaceil is not suitable where it would be in contact with water or for environments with a constant relative humidity above 90%. For wet areas, the following products would be more suitable:

Gyprock Supaceil is manufactured with Optimised Core technology, a stronger, thicker face paper and glass fibre reinforcement. Optimised Core plasterboard has an advanced performance-to-weight ratio, meaning greater breaking strength in a substantially lighter board that continues to exceed the performance requirements of Australian Standard  AS 2588.

Product Options

Gyprock Supaceil is available in a thickness of 10mm and in widths of 1200mm and 1350mm. The long edges of both width boards are recessed for flush jointing and both are designed specifically for use in ceiling installations.

Because of the formulation of the core structure, this plasterboard will provide better resistance to the humid conditions that are experienced in many parts of Australia. It will stay flatter, even when installed on ceiling joists with 600mm centres. There is also less chance of fixings pulling through the board when extra pressure from above is applied such as can be the case with heavy ceiling insulation or when someone accesses the ceiling cavity.

Typical applications:

  • Ceilings in residential buildings.
