Rigitone Matrix 12mm Square (12/25Q) is part of the Potter Interior Systems Perforated Plasterboard range and one of the four edge to edge Rigitone patterns available. Rigitone boards were developed by worldwide plasterboard specialist, Saint-Gobain and are available in New Zealand through Potters’ International Alliance Program. These products feature innovative, VOC reducing Activ’Air technology to help improve indoor air quality.
Boards in the Potter Rigitone Perforated Plasterboard range have been designed for use on ceilings where an increased level of sound attenuation and a high level of aesthetic appeal is required.
The panel perforations together with white acoustic fabric lining and insulation, reduce echo and noise reverberation to create more comfortable environments for work and leisure.
Rigitone Matrix 12mm Square is supplied as a 12.5mm thick sheet, 1200mm wide and 2000mm long.
Rigitone Matrix 12mm Square features a pattern of 12mm square perforations spaced at 25mm centres, providing a 23% open area. The panels are supplied with a white acoustic fabric backing that improves acoustic performance and eliminates dust from ceiling cavities.
NOTE: INDENT ITEM
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:
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.
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.
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 on request.
