Advantages
Airborne noise insulation achieved at R’A,tr > 67 dBA, giving sufficient isolation to meet the levels of emission in common areas.The plastering ensures the impermeability of the wall and its acoustic tightness.Combined absorption into cavity at low, medium and high frequencies.Insulation to low frequency impulse noise.The resonance frequencies of the system are shifted to less audible frequencies.The acoustic membrane improves the insulation at low frequencies of the plasterboard system.Its acoustic insulation capacity can be improved by increasing the thickness of the chamber.Light system providing better results, with low thickness and faster execution.
Application
Machine rooms in residential buildings: hotels, hospitals, teachers and officesMusic venues: pubs, karaokes, discos, party rooms, wedding halls...Music recording studios
