“The acoustic performance of the theatre’s roof was an important consideration for the project,” explains Andrew Chippindall from Taronga Zoo. “The space was required to accommodate very high levels of audio. It is home to a 25-metre screen that will be used to show videos, and provides a versatile space for hosting various presentations and visitor activities. Given the theatre’s proximity to animal enclosures, the roof needed to limit the internal and external noise breakout and control reverberation to minimise discomfort to the animals.”
“The roof of this very special building is highly visible and we realised that it was as important to find a roof system that was refined and could deliver all the technical attributes needed,” commented Alex Kibble, managing director, TKD Architects.
“We were seeking a single system that could meet the acoustic needs of the roof, while also achieving complex geometry, accommodating box gutters and providing an internal finish,” said Robin Sampson, senior graduate of architecture at TKD Architects. “Three systems were considered.
“The traditional system was discounted due to the difficulty in achieving the acoustic performance without installing a separate ceiling, as well as the complications involved in concealing the box gutters in the perimeter of the building. While both proprietary systems met the project’s technical requirements, KingZip was ultimately specified because of its exposed perforated metal trough deck aesthetic, structural span capabilities, and ability to hang services from the roof.”
The roof also features a sound-isolated spacer system and thermal insulation to enhance thermal performance.
Designed to withstand the harsh marine influences of the harbour-side location, the top layer is constructed with aluminium standing seam panels finished in a three-coat PVDF paint system to meet durability and warranty specifications.
