Protone 12mm Square - Perforated Plasterboard
Description

Protone 12mm Square is part of the Potter Interior Systems Perforated Plasterboard range and one of the three contemporary Protone patterns available. Protone 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.

All boards in the Potter Perforated Plasterboard range have been designed for use on ceilings and walls where an increased level of sound attenuation and a high level of aesthetic appeal is required.

The panel perforations together with acoustic fabric lining and insulation, where used, reduce echo and noise reverberation to create more comfortable environments for work and leisure.

Key Features
  • Supplied as a 12.5mm thick sheet, 1200mm wide and 2400mm long.
  • Features eight large square groupings per sheet, each with 400 x 12mm square perforations at 25mm centres, providing a 16% open area.
  • Unlike standard plasterboard, all four edges of Protone perforated plasterboards are recessed to make flush jointing quicker and easier with the normal tape and three coat jointing system. This negates the need for butt joints between full panels.
  • Protone perforated plasterboard is supplied with a highly effective 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

Potter Interior's range of Protone perforated plasterboard provides high levels of reverberation control with much greater freedom for designers:

  • Suitable for both ceilings and walls
  • Plasterboard provides ease of installation and versatility
  • The surface is more durable than mineral fibre or similar acoustic absorbers 
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 specsupport@potters.co.nz
