Select Activ'Air for Cleaner Indoor Environments

With New Zealanders spending much of their time indoors, there is little wonder that there is a strong focus on indoor air quality in building legislation.

Architects and specifiers are actively seeking solutions to reduce the levels of VOCs and other pollutants, particularly for projects where poor air quality can have a more damaging effect such as in hospitals, aged care and education facilities. Activ'Air can be specified for any project where a sterile environment is desired.

Activ'Air is a unique technology developed by worldwide plasterboard specialist Saint-Gobain, that converts VOCs — particularly formaldehyde, into non-harmful inert compounds that are permanently locked in the board and cannot be released back into the air.

Activ'Air technology is built into the new Protone and Rigitone perforated plasterboard options that have recently been introduced to the New Zealand market through Potter Interior Systems' International Alliance program. These products provide exceptional acoustic control and a high level of design flexibility.

Independent testing was conducted at the CertainTeed Research Centre in Blue Bell, Pennsylvania to ISO 16000-23: Indoor air — a performance test which evaluates the reduction of formaldehyde concentrations by absorptive building materials. These tests showed that Activ'Air can reduce the concentration of formaldehyde within an environment by up to 60% when installed in ceilings, even when there is continuous airflow containing formaldehyde.

Installing ceiling and wall linings containing Activ'Air technology will have an enduring impact on air quality and will improve the environment for people working and living in the space.

Rigitone Astral — Perforated Plasterboard

Potter Interior Systems

View Product

Rigitone Astral (8-15-20) is part of the Potter Interior Systems Perforated Plasterboard range and one of the four edge to edge Rigitone patterns available.

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.

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 on request.
