Plenum Barrier Board

Jan. 19, 2018

Designed to isolate sound between rooms in commercial interiors, Plenum Barrier Board achieves up to STC 52 without bulkheads above demountable partitions or full-height walls.

The foil-faced stone wool barrier installs vertically in the plenum above the ceiling and along ceiling walls that stop at ceilings. Conforms around pipes and ducts and expands/contracts with deflection.
