Rockfon® Plenum Barrier Board

Product description Rockfon Plenum Barrier Board is made from pliable stone wool so that it conforms without gaps into tight spaces and around structural members and mechanical, electrical and plumbing elements that may be located in the plenum.  The fiber reinforced aluminum foil facing that is applied to one side increases its sound blocking performance. When positioned above interior partitions that stop at the height of the suspended, acoustic ceiling, Plenum Barrier Board stops noise and speech from traveling between rooms through the plenum above the ceiling.
