Sound Reduction Insulation

Performance Where It Counts

Celbar provides superior sound transfer control demanded by building designers, owners and occupants. Celbar assemblies perform closer to lab tested STC ratings in the field than do other conventional batt and sound board systems. This is due to the complete coverage and the sealing action of Celbar.

Avoid Embarassment

Another very commonly overlooked interior application is controlling sound transmission of falling water, running water or other embarrassing noises. Lavatories, water closets, utility rooms, plumbing lines can be easily insulated against noise during initial construction.

Reduce Noise Between Walls

With the popularity of home entertainment centers, surround sound speaker systems and other sound sources, interior noise pollution must be addressed. Applying Celbar wall spray within interior walls greatly reduces the sound that moves through the wall providing a quieter, more comfortable room.


Reduce Noise Between Floors

Celbar Wall spray, applied between floors of multi-level dwellings helps reduce airborne noise such as voices, radios, televisions and other annoying sounds. In combination with resilient channels, Celbar wall spray reduces the impact or foot-fall noises that are very common.
