The project involved the replacement of a section of noise wall on the John Renshaw interchange at Tarro, NSW.
RMS selected HushPanel, an effective noise wall invented and manufactured by Hushpak Engineering. With a sound transmission class of 25 (STC 25), HushPanel was very effective in reducing noise from vehicle traffic. Designed to ensure quick and easy installation, HushPanel was erected with minimal installation time, thereby reducing lane closures and traffic delays on John Renshaw Drive. Thirteen panels spanning over 31 meters were manufactured from Colorbond Monument and installed with aluminium frames.
