SONIE BS +
- Rectangular
- Lightweight, high-performance acoustic splitter for ductwork systems.



Characteristics
The SONIE BS+ is a high-performance acoustic splitter designed for ventilation and air handling ductwork systems. It effectively reduces noise generated by HVAC installations.
Its reduced weight compared with a standard acoustic splitter improves on-site handling and installation. This weight reduction also makes it possible to optimize splitter dimensions, increasing the overall attenuation performance of the silencer.
Characteristics
- DX51+Z275 galvanized steel frame
- Rounded aerodynamic profile
- Mechanical reinforcement by ribbing
- High-performance glass wool insulation
- Insulation density: 24 kg/m³ ±10%
- Fire classification: A2-s1,d0 (M0)
- Anti-fibre-release glass veil protection
- Available thicknesses: 50 / 100 / 150 / 200 / 300 mm
Performances
- Acoustic performance
- Tested in an independent laboratory in accordance with EN ISO 7235
- Acoustic improvement of up to +15 dB at low frequencies compared with standard insulation
- Pressure loss
