When absorbers cannot reduce all the noise, barriers are needed to block the sound. Flexible mass loaded vinyl (MVL) prevents sound from traveling from one area to another. This layer is typically combined with absorbers and decoupling materials to create a composite material that can absorb and block noise all in one.
- Custom barrier weights are available for each application.
- Can be combined with wear surfaces to create floor mats that reduce sound.
- Can be combined with sound absorber materials to create acoustical composites that absorb and block sound all in one.
