MINNEAPOLIS--PROSPEC(R) Barrier from illbruck helps to create quieter offices and conference rooms by blocking noise transmitted from machinery in adjacent work areas. The high-density vinyl barrier is installed over substandard walls to contain noises created by generators, HVAC, or other equipment. Rated to block up to 26 decibels of noise, PROSPEC Barrier helps to reduce stress and fatigue caused by excessive or recurring noise. In offices with dropped or suspended ceiling, PROSPEC Barrier is fastened to the original ceiling and allowed to hang down to the suspended ceiling panels. The resulting wall extension blocks noise from leaking through an otherwise open cavity. For more information call (800) 662-0032 or visit www.illbruck-sonex.com.
