CLT Acoustic Performance

WS TDG 44 CLT Acoustic Performance Cover
This guide contains the results of a research program into the acoustic performance of CLT in various system configurations, with the aim of demonstrating compliance with the NCC. The acoustic testing was managed by PKA Acoustic Consulting and carried out at New Zealand’s Auckland University Acoustic Laboratory.

Introduction

As CLT panels are available from different suppliers, the study used test panels from various manufacturers. The same CLT panel configuration from multiple suppliers was tested to allow for the variability of CLT products.

The results show that with attention to design detail, CLT panels can readily meet or exceed the regulatory acoustic requirements in the Australian market.
