The project specification included Kinetics Noise Control, Inc. (KNC) for equipment vibration isolation. The representative discussed this project with the mechanical engineering firm and acoustical consultant. Because of their long time experience with KNC’s HVAC equipment vibration and architectural noise separation products and services both the mechanical firm and acoustical consultant also preferred KNC’s sound attenuators for the project.

NOISEBLOCK™ Applied Products

KNC model VRS, straight, rectangular silencers were supplied. They were constructed of 18 gage solid outer skin and 22 gage perforated inner baffle skin all material was galvanized steel, Type G90. The acoustic grade fill was encapsulated in a Tedlar® erosion barrier including an acoustic spacer.

The project consisted of two (2), intake silencer banks each 12'-0" H x 68'-0" W x 9'-0" L and each bank constructed of sixty (60) 40.5" W x 47.5" H x 108" L smaller silencers and six (6), discharge silencers each 14'-0" H x 12'-0" W x 7'-0" L and each bank constructed of thirty-six (36) 47.25" W x 41.625" H x 84" L smaller silencers.

After installing all discharge and intake silencer modules, the contractor used field applied angle flanges to band and connect the silencer banks to the building structure.


KNC’s manufacturing team and the representative worked closely with the mechanical contractor to fabricate and deliver product to coincide with the contractor’s installation schedule. The time-line was met. The architect and acoustical consultant praised the work and highly recommend KNC for future projects.
