Sound proofing of heating, ventilation and air conditioning systems

Reducing the noise level in a boiler / utility room

With its napped surface, our soni WAVE foam substantially attenuates the noise in boiler rooms or in utility rooms accommodating ventilation or air conditioning devices. When the ceiling and/or walls are completely covered with this “egg crate” foam, the noise level in the room will drop substantially and, in addition, the remaining noise will largely be prevented from passing to adjacent or upstairs rooms. In case that the installation needs to comply with fire safety regulations (B1), we recommend the use of soni RESIST, which offers both sound-insulating and sound-attenuating capability.


Retrofit solution for ventilation systems

A centralized ventilation system is a very practical amenity, but in many cases it has the disadvantage of being noisy. When operating at the highest setting, it may produce annoying flow noises, compromising the comfort at home respectively interfering with concentration at work.
Now it is easy to retrofit standard ventilation systems with an effective noise-control solution: soni RSD duct silencers. Our soni RSD duct silencers are mounted directly on the air intake / outlet of the ventilation system, and mechanically fixed. Air velocity at the intake / outlet will only be negligibly lower - but the flow noises are effectively minimized, allowing the system to provide fresh air “in silence”.
