Airborne noise insulation achieved at R’A,tr > 60 dB, giving sufficient isolation to meet the levels of emission in common areas.The plastering ensures the impermeability of the wall and its acoustic tightness.Absorbent at medium and high frequencies.Shifts system resonance frequencies to less audible frequencies.The acoustic membrane improves the insulation at low frequencies of the plasterboard system.Its thermal and acoustic insulation capacity can be improved by increasing the thickness of the structure and mineral wool.Light system providing better results, with low thickness and faster execution.
Local daytime hours: cafes, restaurants, bars.Places of public attendance: auditoriums, cinemas.Commercial basses: workshops, builders.Discotheques in isolated buildings.
