Sound Control

Celbar wall insulation effectively reduces sound transmission from walls or ceilings adjacent to entertainment centers, surround sound systems, bathrooms, and bedrooms to other rooms. The high-density insulation fills voids and creates a monolithic seal resulting in a quieter, more peaceful home. Celbar also provides a very high R-value making a home more energy efficient. Celbar is classified as a green building material, is designed to resist fire, mold, mildew and insects. Celbar has always been formulated with 100% Borate additives and is free of all Ammonia additives.

System Description

Celbar is a blend of specially prepared cellulose fibers, organic in nature, treated with adhesive and fire resistant chemicals. When sprayed in place, the interlocking fibers result in a mass that produces excellent sound and thermal properties.

Fiberglass often leaves holes for air to escape while Celbar seals the entire area

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.

Between Floor Application for Celbar Wallspray

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 Floors

Celbar Wall Spray, applied between floors of multilevel 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 very common in today’s homes.

The performance of Celbar compared to other identically constructed wall systems, as documented by laboratory tests is shown below.
