About BRD HUSH SCREEN™ Rooftop Equipment Barriers:  

HUSH SCREEN™ Mechanical Screening Systems provide architecturally pleasing visual barriers for all types of mechanical equipment.  A variety of panel styles and colors are available with optional HUSH QUILT inserts to boost acoustical performance.  The panels slide in a track rail frame system to facilitate easy access for equipment maintenance and service.  The framing system cantilevers off and is supported by the mechanical equipment, thus eliminating the need for roof penetrations.



Acoustical HS Screens

In addition to the standard "screening" purpose of the HS panel systems, acoustical elements can be added to reduce unwanted HVAC equipment noise.  Using our HUSH QUILT™ QAB-200-PM Quilted Curtain Absorbers, the HSA-200 panel system can achieve an overall STC (Sound Transmission Class) of 37 and NRC (Noise Reduction Coefficient) of 0.70.  See chart below for octave band acoustical performance of the HUSH SCREEN™ HSA-200 Acoustical Barrier Screens.
