HUSHCORE® High Performance Rooftop Unit Noise Control Designs address system based problems associated with curb mounted downflow packaged air handling equipment.
Acoustical Curb Designs for high performance projects are integrated solutions that address all transmission paths. Dialogue early in the design process allows the necessary coordination of curb acoustical elements with building ductwork. High Performance HUSHCORE® Systems usually have optimized acoustical and aerodynamic performance in the form of scheduled sound pressure levels by octave band for the unit/curb assembly and often are customized to meet specific target NC levels in critical building spaces.
Each of the High Performance Systems is rated in four categories from Fair to Best. Guide Specifications, Details and Data Sheets are available for each case.
