AcoustiSorb - Sound Absorbing Walls

Our AcoustiSorb composite panel is a star performer in the field of sound absorption and attenuation. 

Increasingly, with the constant push of development into residential areas and expansion of rail corridors, commercial HVAC units, machinery enclosures and loading docks, the need to absorb sound as opposed to simply reflecting it away by breaking the line of sight is becoming very important. 

Sound Absorbing barrier walls and enclosures can dramatically reduce the noise in all directions thus providing a peaceful environment for surrounding workers or residents.
