Gyprock Supaceil

Gyprock Supaceil is part of Gyprock’s standard 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.

This plasterboard contains more plaster and unique stiffeners with fibreglass reinforcement for greater strength and sag resistance.

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 in Australia and accredited to Australian Standard AS2588 through SAI Global. The core incorporates patented Controlled Density (CD) technology and the heavy-duty face paper is an off-white colour.

Controlled Density Technology (CD)

Gyprock Supaceil is made up of a gypsum plaster core that is wrapped in heavy-duty linerboard paper with bonded edges. Controlled Density technology allows the board’s core structure to be manipulated. CD technology produces a core structure that is denser at the faces of the board with a gradual increase in aeration towards the centre of the core.

Controlled Density technology delivers a number of important benefits:

  • Higher density at the face of the plasterboard for greater strength
  • Reduced mass for a lighter weight board that’s easier to handle
  • Superior face paper to core bonding for superior score and snap properties

Controlled Density technology helps Gyprock set the benchmark for 'standard' plasterboard in the Australian market.

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.

Gyprock Supaceil also achieves superior sound isolation and is suitable for use in acoustic rated applications.

Typical applications:

  • Ceilings in residential buildings.

Plasterboard Manufacture

Gyprock Supaceil is manufactured to comply with AS/NZS 2588 Gypsum Plasterboard. Gyprock factories conduct regular testing under a Quality Management System complying with ISO 9001/2000.

Plasterboard Installation

AS/NZS2589: Gypsum linings – Application and Finishing outlines the procedures for the installation and finishing of Gyprock Supaceil in conjunction with additional details contained in Gyprock Technical Literature.

Levels of Finish

A Level of Finish sets out the minimum specifications for installation processes from framing preparation to painting and decoration. The levels are defined in AS/NZS 2589.1, and are intended to provide builders, installers and homeowners with defined methods and practices necessary to meet expectations in terms of the Level of Finish. They are not applicable to fire rated construction.

The level of finish should be specified prior to construction as it can be affected at different stages of construction and tolerances must be adhered to:

  • Frame construction
  • Plasterboard fixing and back-blocking
  • Plasterboard jointing and setting

A Level 3 Finish is for areas that do not require painting and decoration such as above ceilings and inside service shafts.

A Level 4 Finish is the generally accepted level for domestic construction

A level 5 Finish should be specified wherever gloss, semi-gloss or dark coloured paints are to be used, or where critical glancing light conditions are likely.

More information on Levels of Finish can be found in the Gyprock Residential Installation Guide

Painting and Decoration

Finishes applied to plasterboard surfaces can have a significant effect on the perceived quality of the installation, particularly where critical lighting conditions exist.

  • Textured or heavy patterned finishes tend to hide imperfections
  • Matt finishes minimise imperfection visibility
  • Semi-gloss and gloss finishes highlight imperfections
  • Light colours are less likely to show imperfections and impact damage

Gyprock recommends paint systems consisting of one coat of a plasterboard sealer followed by two coats of finishing paint. Always follow the manufacturer’s instructions for application and recoating.

Gyprock recommend decoration in line with Master Painters Australia.
