Rigitone Matrix 8mm Round — Perforated Plasterboard
Description

Deliver an aesthetic impact and significantly improve acoustics with Rigitone Matrix 8mm Round. The edge-to-edge pattern layout, unique installation method and benefits of Activ'Air make Rigitone a superior option.

High levels of acoustic absorption are achieved through a combination of perforation patterns and a highly effective black acoustic fabric backing which also prevents dust from the ceiling entering the room and masks the ceiling framework. 

Key Features
  • Rigitone Matrix 8mm Round is a 12.5mm thick sheet, 1188mm wide and 1998mm long.
  • Rigitone Matrix features a pattern of 8mm round perforations spaced at 18mm centres, providing a 15.5% open area. 
  • Rigitone perforated plasterboard is supplied with a highly effective white acoustic fabric that dramatically improves the acoustic performance of the board. This unique fabric is exclusive to Potter Interior’s and apart from improved acoustic performance, it provides other benefits:
    • Eliminates dust from ceiling cavities coming down into the room
    • Effectively masks the ceiling framework so that it is not seen from below through the perforations
    • Contributes to better fire protection compared to a board without fabric backing
Scope of Use

Rigitone is specially designed to be screw fixed to suspended ceilings.

Its unique installation method allows the product's perforated pattern to continue undisrupted where sheets meet. Unlike the traditional three coat plasterboard jointing systems, Rigitone boards are jointed by directing a specialised compound into a gap between the sheets. The filling method is made possible by the unique Rigitone Filler Accessory Kit, combined with the Rigitone Filler compound.

While all four edges of Rigitone sheets are pre-primed, cut edges must be sealed with Rigitone Primer prior to installation, readying the surface for the filler compound.

Limitations on Use

Perforated plasterboard is not recommended for installation in areas subject to greater than 70% relative humidity including indoor swimming pools and bathrooms. Protone boards support point loads up to 3kg. Adequate independent or additional support must be provided for services and lighting systems that exceed this limit.

Other Performance Attributes

Acoustic assessment 

A material's sound absorbing properties are expressed by the noise reduction coefficient (NRC), a simple measure that averages the absorption values over just a few frequencies. NRC typically ranges from 0 (total reflection) to 1.00 (total absorption). For perforated products, the NRC is dependent on the amount of open surface area, the type of acoustic fabric, the use of additional insulation material and the depth of the air cavity (plenum) behind the lining. Boards in the Rigitone and Protone ranges were tested for sound absorption in CSIRO Melbourne and Auckland University laboratories. Testing was performed with air cavities of 200mm and, in some cases 600mm, with and without insulation (50mm CSR Bradford glasswool batts at 14kg/ m³). PKA Acoustic Consulting provided complete acoustic predictions based on this data for the Rigitone and Protone ranges and previous testing data for the Standard 6mm Round board, along with perforated and slotted resonance formula calculations, as well as their database of sound absorption coefficient and acoustic laboratory tests. The acoustic absorption results graph shows the absorption coefficients for all boards in the perforated plasterboard range, with an uninsulated 200mm cavity installation. The table in the attached brochure provides a quick comparison of the range’s NRC values. Copies of the test reports are available by emailing [email protected]
