Acoustic Treatments

NAP Silentflo are the only Australasian company with independently laboratory certified acoustic solutions for almost every acoustic application, whether it be commercial, architectural, or industrial. 

NAP’s acoustic wall linings & flow resistive absorptive panels are ideal for reducing overall noise levels and improving speech intelligibility in reverberant spaces, while their absorptive barriers are an eco-friendly alternative for reducing environmental noise.

Performance is backed with extensive independent laboratory testing of the insertion loss, regenerated noise level, and aerodynamic performance across the whole range, together with an on-going program of continual product development at their test facilities in Melbourne and Hong Kong.

Cooke Industries have represented NAP in New Zealand for over 40years, and manufacture their entire acoustic products range under license here in New Zealand.  We provide a complete acoustic solution, including:

  • Specialist advice for solving your problem in the most cost efficient manner.

  • A tailored acoustic solution, including bespoke design if required.

  • Local manufacture in our purpose-built facilities with backup from NAP’s factories in Australia, the Far East, and Europe.

NAP noise barriers and absorptive wall linings provide reverberation control in large spaces to create a more comfortable acoustic environment.
