Gyprock Perforated

Gyprock Perforated Plasterboard has been designed for use on ceilings and walls where increased levels of sound attenuation is required.

As the name implies, the acoustic properties of the board are achieved by perforations to approximately 8% of the board surface that absorb sound to reduce echoes and reverberation. The long edges of the panels are recessed for flush jointing to a smooth, continuous surface.

Gyprock Perforated Plasterboard is manufactured in Australia to Australian Standard AS2588 and the heavy-duty face paper is a buff colour.

Controlled Density Technology (CD)

Gyprock Perforated Plasterboard 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.

Plasterboard Manufacture

Gyprock Perforated Plasterboard is manufactured to AS/NZS2588 Gypsum Plasterboard.

Plasterboard Installation

AS/NZS2589: Gypsum linings – Application and Finishing outlines the procedures for the installation and finishing of Gyprock Perforated Plasterboard 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.
