  • Soundproofing panel suitable for the realization of any type of layered masonry.
  • Fully waterproof and small in size, can be easily moved on site.
  • Made up of incombustible components.
  • At the same overall dimensions, it allows to obtain markedly superior sound insulation compared to only using fibrous materials.


After the completion of the first brick layer and rendering (always recommended), lay the ACOUSTICBAG panel over the entire surface of the wall, making sure to draw near the panels without leaving spaces. The perfect continuity of the laying may be facilitated by the use of a sealant tape to be applied to view along the contact surfaces between the panels, which can be bound to the first brick layer by mechanical plastic anchors. 

The ACOUSTICBAG panels can also be applied without fastening, still taking care to ensure the perfect continuity of laying.

Particular care must be placed in the interface between the brickwork and concrete pillars, in correspondence of which will have to be adopted special precautions in order to avoid the formation of acoustic bridges. We recommend making the second brick layer at 1 cm distance from the ACOUSTICBAG panel.
