Acoustic Louvres for Heating, Ventilation and Air Conditioning Noise Solutions

Sound Planning supplies and installs acoustic louvres for heating, ventilation and air conditioning applications in plantrooms, acoustic enclosures and vents.

Acoustic louvres provide attenuation (noise reduction) whilst maintaining required air flow, please call our engineers to assist in your acoustic louvre design queries.

  • Typically used in building openings, they reduce airborne noise while allowing continued airflow
  • They are also used as acoustic screens around mechanical plants where equipment requires airflow

Tested in the laboratory facilities at Salford University, which is accredited by UKAS (United Kingdom Accreditation Service), a Sound Reduction Index (SRI) for each louvre type can be published upon request.
