Using an aerodynamic structure designed to reduce sound pressure, acoustic louvres provide attenuation (noise reduction) while maintaining the required airflow.
- Typically used in building openings
- Reduce airborne noise, while allowing continued airflow and ventilation
- Can be used as acoustic screens around mechanical plants where equipment requires airflow
- Often found in boiler and plantrooms in residential areas or on rooftops
- Industrial applications include power stations, cooling towers, chemical treatment plants
Tested in laboratory facilities at SRL in Suffolk, Sound Planning supplies and installs acoustic louvres for heating, ventilation and air conditioning applications in plantrooms. A Sound Reduction Index (SRI) for each louvre type can be published upon request.
Features
- Rugged and durable material
- Long lasting
- Dummy sections, non-acoustic
- Bird mesh on the rear
- Special fixing details, e.g., external/internal flanges
- Different construction options:
- standard units to be installed in building work openings
- bespoke units to suit a wide range of different requirements
- Provides good ventilation
- Gives protection against the weather
- Acoustic infill materials that help to reduce noise levels
- Single or double banked depths
Acoustic louvres can be supplied in five different depths (overall reductions):
- 150mm (Rw 11dB) NR 17dB
- 270mm (Rw 12dB) NR 18dB
- 300mm (Rw 14dB) NR 20dB
- 300mm (Rw 16dB) NR 22dB
- 540mm (Rw 22dB) NR 28dB
Acoustic louvre panels (overall reductions):
- 50mm (Rw 32dB) NR 38dB
- 100mm (Rw 34dB) NR 40dB
Units can be supplied in a variety of finishes to suit the application:
- Pre-finished galvanised sheet steel or aluminium
- Polyester powder paint (RAL or BS colours)
- Plastisol
- Anodised (aluminium only)
Models
The standard models are classified into two types:
- Type R
- Pressure drop: normal
- Acoustic performance: optimum
- Type LP
- Pressure drop: minimum
- Acoustic performance: normal
Components
Doors
Our louvre door systems provide access to plant rooms, reducing noise levels by 17dB to 22dB. They are supplied with:
- Lockable hardware
- 150mm to 300mm depth
- Box section frame
- Painted in RAL or BS
- Hinged on either side
- Installation services
Screens
Louvre screens reduce noise by creating a different path for the noise source going to the receiver.
- AC plant screens
- Generator screens
- Chiller screens
Other Services
- Noise reduction calculation services
- Full installation
- CAD drawings
