 Gyprock Plasterboard CD


Gyprock Plasterboard CD is part of Gyprock’s standard range of premium quality plasterboards.

It is used for general internal wall and ceiling linings in residential and commercial projects where no specific fire, acoustic or moisture resistant requirements are specified.

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

Gyprock Plasterboard CD 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 a buff colour.

Controlled Density Technology (CD)

Gyprock Plasterboard CD 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 Plasterboard CD is available in 10mm and 13mm thicknesses in 1200mm and 1350mm widths. 10mm is predominantly used for residential applications in standard installations, where door frames and window reveals are generally designed for a 10mm internal lining. 13mm is generally used in commercial environments where a more robust lining is desired.

In a horizontal setout, the 1200mm sheet width suits standard 2400mm ceiling heights and 1350mm suits 2700mm ceilings. In commercial applications, plasterboard is often installed vertically to cater for higher ceilings.

Gyprock Plasterboard CD is also available in different edge profiles for a variety of installation options.

Gyprock Plasterboard CD – Recessed edge (RE) profile

RE is the standard profile for most plasterboard where both long edges of the board feature a recess that tapers approximately 60mm in from the edge. When butted together, these long recesses assist in producing a smooth, even and continuous surface when a jointing system of tape and compound is correctly applied.

Typical applications:

  • Residential walls and ceilings
  • Commercial, non-fire or acoustic rated walls and partitions

Gyprock Plasterboard CD - Square edge (SE) profile

SE has no recesses on any edge. This allows sheets to be butted together neatly to form a square finish or inserted into H moulds for wall panelling.

Typical applications:

  • Mainly used in commercial projects for partitioning where the edges/joints will be covered by aluminium, vinyl or timber.

Gyprock Plasterboard CD – Recessed edge/square edge (RE/SE) profile

RE/SE has one square edge and one recessed edge and is manufactured as a wider sheet (1210mm). This combination allows the square edges to be placed at the floor and ceiling with standard horizontal jointing where the boards meet.

Typical applications:

  • Mainly used in commercial projects for partitioning where the plasterboard’s recessed edge would be visible
  • Ideal for use with narrow cornice (eg. 55mm), square set ceilings or where small skirting board and architrave profiles are desired

Plasterboard Manufacture

Gyprock Plasterboard CD 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 Plasterboard CD 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

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.
