Acoustic and decorative ceiling and wall finishes from specialist manufacturer Asona are an integral feature of the award-winning student accommodation built for the University of Auckland. The 55 Symonds Street project by architects Ashton Mitchell, Hawkins Construction and Alpha Interiors incorporates an acoustic solution for the different zones of the building’s entry and common areas, addressing noise control and contributing to the overall design language of the building.
Asona manufactured a custom Triton 15 acoustic ceiling panel to span the full width of the corridor, creating a cleaner ceiling aesthetic with sound absorption benefits. The large open plan study/dining area required a high noise reduction coefficient (NRC) acoustic treatment to control sound reverberation.
Asona Triton Cloud panels in 25-, 50- and 75-millimetre thicknesses were wrapped in four tones of fabric, producing an overall NRC of 1.00. These panels were installed in a 3D arrangement to effectively control the acoustics of the space, while also adding drama and interest to the ceiling. Importantly, the performance of these panels prevents transmission of sound to student accommodation directly above.
For the reception area ceiling, Triton Baffle Beam 40 mm in white Sonatex glass laminate was applied to follow the curved wall leading into the study/dining zone. This design feature accentuates the curve of the building, provides additional acoustic control and creates a sense of flow to encourage movement through the transit area.
The external language of the building was also reflected in the interior. The rectangular modules of the facade inspired the main feature walls in the multi-functional, open plan study lounge and games room space. Asona manufactured and installed Triton Fabwall 40 in varying lengths, wrapped in Textilia Bond Leaf fabric with a 40-mm reveal around each rectangular panel. The varied lengths and wide reveals softened these two-storey walls, avoiding the overpowering effect of tightly fitted panels.
Ashton Mitchell architect Clifford Paul commented, “We wanted to create a vibrant space that reflected the students using the facility, avoiding commercial finishes to maintain the feeling of a home. We use Asona products regularly to provide acoustic control and, in this project, to allow the use of fabrics and introduce subtle colours to the interior.”
Asona has partnered with USG Boral as distributor to bring its innovative, high-performance decorative acoustic ceiling and wall finishes to Australia.
