Ultra-thin liquid coating for sound insulation that acts as a barrier to sound waves!
Liquid soundproofing coating
Bronya Sound Barrier
Bronya Sound Barrier is an ultra-thin liquid soundproofing coating that acts as a barrier to sound waves. It reflects sound waves and does not allow them to penetrate the room. However, its use as a damping layer between two (or more) layers of sheet materials allows for more effective enhancement of properties:

The material can be used for sound insulation of building envelopes and structures, and it reduces noise produced by railway cars, ventilation boxes, motor vehicles, and other equipment. It is also possible to protect various envelope and load-bearing structures from external noise.
Sound insulation work can be performed at surface and ambient temperatures from +15°C to +70°C (the critical value for surface and ambient air temperature is +10°C at the time of application and drying of each layer within 24 hours). The working temperature of the Bronya Sound Barrier modification ranges from -60°C to +70°C.
Attention! We have two schemes for using Bronya sound insulation:
- Less efficient, but simpler way:
Apply a layer of Bronya Sound Barrier coating 1.5-2 mm thick to solid plywood or drywall and immediately attach it to the wall, ceiling, or floor (depending on where the noise source is). The structure can be finished with any decorative and finishing materials on the top side. - The following diagram has greater efficiency:
Apply Bronya Sound Barrier with a thickness of 1.5–2 mm to solid plywood or drywall and attach a plywood or drywall panel to it, then bond this structure to the wall, ceiling, or floor (depending on the noise source). The top of the structure can be treated with any decorative and finishing materials.
Packaging and Modifications
Available in 10 and 20 liter packaging.
There is also Non-flammable modification!
The 20L plastic bucket of Bronya Sound Barrier soundproofing coating weighs only 11 kg. During proper transportation and storage, the microstructure of Bronya liquid soundproofing remains unchanged.
