Case study
Application: Sound Absorbing Walls for Rooftop HVAC Wall Product: AcoustiSorb Manufacturer: ModularWalls Product: Martini Absorb Performance: Sound Absorption
Application Overview
Commercial HVAC units are often located on rooftops to save space and provide easy access for maintenance. Rooftop HVAC units can create an acoustic design challenge for architects, especially when the HVAC units can be seen and heard from neighbouring multi-storey apartments.
Rooftop HVAC units typically incorporate a series of motors, fans and chillers that produce a range of noises such as throbs, rumbles, whistles, whirrs and hisses. If these noises aren't acoustically treated they can have an adverse impact on the surrounding environment and affect the health and wellbeing of neighbouring residences.

ModularWalls manufacture an aesthetic noise attenuation barrier called AcoustiSorb. AcoustiSorb is a pre-finished aluminium modular wall panel system that's commonly used to enclose rooftop HVAC units.
The panels are slotted into place between supporting posts with their perforated surfaces faced inwards towards the noise source. Martini Absorb is at the core of the panels, and because of its HD, XHD, XXHD density variations, the panels can be tuned to meet specific absorption requirements across a range of frequencies.
