Boët StopSon straight-blade (LD) or curved-blade (LC) acoustic ventilation grilles can be adapted to the specific openings and aesthetics of any type of building.

Our acoustic ventilation grilles are designed to allow air to circulate (limiting pressure loss) while protecting the environment effectively from unwanted noise.

Boët StopSon also offers acoustic door assemblies composed of acoustic ventilation grilles that integrate perfectly into an overall structure.

The LD and LC grilles have a wide range of characteristics:

  • Acoustic performance (depending on thickness)
  • Airflow performance (depending on thickness and type – LD or LC)
  • Construction (steel, aluminium, Inox)
  • Dimensions (made-to-measure)
  • Shape (square, rectangular, round…)
  • Finish (galvanised, powder paint, liquid paint...)
  • Accessories (bird deterrents, flanges...)

In-tunnel or face-mounted or in a door assembly (single or double casement)
