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. Celbar effectively reduces sound and heat transfer by creating dead air spaces between and within its fibers. This process seals cracks and holes in the wallboard, around plumbing and electrical outlets, vent ducts and other irregularities. There are no compressed areas or voids to allow sound leaks, R-value reduction, or air infiltration.

How does Celbar Work?

Celbar encompasses the entire cavity and has an R-value of 3.8 per inch. Celbar also stops air infiltration, keeping a cool house cool, and a warm house warm.

How is Celbar Installed?

1.

Celbar is spray-applied in wall, floor, and ceiling cavities to form a monolithic coating.

2.

Celbar is applied just beyond the studs ensuring maximum coverage. Celbar is then planed flat creating an even, complete thermal barrier.

Sound Control

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.

Compare Insulations
