Roof Top Unit RTU Sound Barrier - Case Study
eNoise Control received a call from a Pharmaceutical Manufacturer in a
large metropolitan area. City officials had visited their establishment
several times and issued them a citation for breaking the city's
ordinance. The problem began with purchase of a new Chiller unit as added
in a recent expansion.
eNoise Control proposed the installation of
outdoor sound curtain
barrier wall panels to be mounted on steel frames (by others). The outdoor
sound curtains panels are 54" wide and cut to length per the application.
They have mating exterior grade velcro on the vertical seams of each panel
that are joined together to form each wall. Grommets are installed across
the top and bottom of each panel used for suspension. The panels are
constructed of a 1lb. per square foot reinforced vinyl sound barrier
bonded to a nominally 1 inch thick acoustical absorber faced with a
silicone impregnated weather proof cloth. The composite sound curtain
material has superior UV and heat resistance.
eNoise Control expedited the manufacture of the curtains and the
solution was installed in time for the next Noise Review by the city.
