Acoustic barriers NEW PRODUCT

Acoustic barriers (panels) - the purpose of using the acoustic barriers is to separate the sources of
noise (for example fans, cooling units, compressors and other equipment) from the structure of
buildings, houstings of ventilation central stations or from the surroundings. Acoustic barriers are made
as panels and filled from the side of the source of noise with mineral wool covered with a veil of glass
fibre (ISOVER Ventilux 6335 or Rockwool Industrial Batts Black 60). The surface of the acoustic panels
may be covered with perforated sheet metal. Acoustic panels characterized with a wool thickness

above 50 mm have a sound absorption coefficient of aW > 0,95, so they meet the requirements of

`A` class of noise absorption (according to EN ISO 11654). Maximum permissible air flow velocity is
20 m/s. Such acoustic barriers have been made and installed in the following structure:

- Reichstag building in Berlin,
- Hypo-Haus building in Munich,
- Zˇote Tarasy retail complex in Warsaw.
