Acoustic Louvres

ACRAN Acoustic Louvres are designed to provide optimal acoustic performance (noise reduction) with minimal airflow restrictions. The acoustic louvres are typically manufactured from galvabond to suit any opening size. Where required the acoustic louvres and can be assembled in a modular fashion.

ACRAN Louvres can be supplied in multiple finishes including plain galvabond, powder coated or painted.

ACRAN Acoustic Louvres can be also manufactured as a hinged or sliding doors. The doors are fitted to stiffened galvabond or zinc anneal frames and fitted with hardware as required for the individual applications.

The louvres are laboratory tested to Australian Standards in our own Acoustic Testing Facility.

If required, Acran can manufacture an acoustic louvre from other materials including 304 & 316 stainless steel to provide additional corrosion protection in harsh environments.

As with all Acran products, we employ our own installation staff familiar with the installation methods required to ensure acoustic integrity. Where required or preferred we can easily assemble a complete turnkey solution.

Should you have an application requiring specific acoustic performance please contact our office and we can provide additional options from our extensive range of Australian Standard tested products.
