BRONYA SOUND BARRIER – this is an ultra-thin liquid sound insulation coating that acts as an obstacle in the way of sound waves. It reflects the sound stream and does not allow it to pass into the room. However, its use as a damping layer between two (or more) layers of sheet materials makes it possible to strengthen the properties more effectively:
Material | Sound insulation index R, dB |
Ultra-thin sound-proof coating Bronya Sound Barrier 1 mm thick | 20 |
Ultra-thin sound-proof coating Bronya Sound Barrier 1 mm thick on 1 sheet of drywall 12 mm | 30 |
Partition of 2 sheets of plasterboard of 12 mm with 50 mm mineral wool | 36 |
Foam concrete M 300 100 mm thick | 29 |
Two glasses with a thickness of 6 mm and an air gap of 12 mm | 26 |
Monolithic door with a thickness of 60 mm with a seal | 30 |
Glass | 23 |
The material can be used for sound insulation of enclosing structures of buildings and structures, it reduces the noise produced by railway cars, ventilation boxes, motor transport and other equipment. It is also possible to protect various enclosing and supporting structures from external noise.
Sound insulation works can be carried out at a surface and ambient temperature from +15°C to +70°C (critical value of surface and ambient air temperature +10°C at the time of application and subsequent drying within 24 hours of each layer). The operating temperature of the BRONYA SOUND BARRIER modification ranges from -60 °C to +70 °C.
Attention! We have two schemes for the use of sound insulation "Bronya":
– Less efficient, but easier way:
Apply 1.5-2 mm Bronya Sound Barrier to solid plywood or drywall sheet and immediately attach it to the wall, ceiling or floor (depending on what is the source of noise). From above, the structure can be processed with any decorative and finishing materials.
– The following scheme has greater efficiency:
Apply a 1.5-2 mm Sound barrier Bronya to solid plywood or a sheet of drywall and attach a sheet of plywood or a sheet of drywall, and already glue this structure to the wall, ceiling or floor (depending on what is the source of noise).The top of the structure can be treated with any decorative and finishing materials.
The use of the above schemes is the most effective application of Bronya Sound Insulation, as well as budget compared to any other vibroacoustic systems.
