The best sound experience…
Most acoustics standards and guidelines require a Sound Transmission Class (STC) of 45 or 50 between rooms. Examples include classrooms, medical examination and treatment rooms, and executive offices and conference rooms.
On their own, acoustic ceiling tiles and an open plenum provide sound insulation levels equivalent to STC 20-35, which does not comply with most standards.
As noted, an STC 45 to 50 level can be achieved by extending the walls to full height.
Alternatively, positioning our Plenum Barrier Board vertically above the partial-height wall to block the plenum also can yield insulation levels equivalent to STC 45-50 when combined with our stone wool ceiling systems.

Some building owners choose partial-height walls to save costs during construction or remodeling. For further savings, plenum barrier boards also can decrease the cost of the ceiling. They allow for greater aesthetic flexibility with interior finishes and floor plans while preventing the need to control noise leaks through the ceiling system.
Helping minimize installation time and associated costs, Rockfon Plenum Barrier Board’s foil-faced, stone wool barrier installs quickly above interior partitions. It is placed vertically in the plenum above the ceiling along interior walls that stop at ceiling height. It also can be used under partitions in raised-floor plenums. The lightweight material is easy to cut and lift into position. It conforms around pipes and ducts, and expands and contracts with deflection.
In addition to its acoustic qualities, our products support long-term savings as stone wool resists fire, water, moisture, humidity, microorganisms and mold. Rockfon complete ceiling systems contribute to safe, healthy, sustainable, comfortable and beautiful buildings.
