Acoustic floors for the largest mass timber office building in New Zealand

We’re proud to see our Tranquillo Acoustic Floor System helping set a new benchmark for sustainable design at 90 Devonport Road — the country’s largest mass-timber office building. Designed by Warren & Mahoney and built by L.T. McGuinness, this eight-storey project demanded exceptional sound control, fire performance and structural integrity — and our system delivered.

With its open-plan layout and timber structure, achieving acoustic separation was critical to the success of the design. The Tranquillo system provided a complete solution — combining pre-assembled battens, insulation, and a high-density substrate to reduce impact and airborne noise while maintaining a lightweight, efficient build.

Read the full case study to see how Tranquillo helped achieve outstanding acoustic results on this landmark project.

“It’s an office environment, so acoustic separation was essential. The system also gave us flexibility with cabling and helped with fire compliance. It ticked every box.”
