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

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.
The performance of Celbar compared to other identically
constructed wall systems, as documented by laboratory tests
is shown below.
The base system and results are as follows:

Thermal Performance |
|
Celbar's R-value of 3.8
per inch allows you to design exterior wall systems with
higher total R-values. However, R-value alone is not the
only measure of a product's thermal effectiveness. To obtain
maximum thermal efficiency, air infiltration must be
minimized. Sprayed in place, Celbar conforms to any
substrate, around pipes, obstructions, and over cracks,
reducing air infiltration and forming a highly efficient and
effective thermal barrier. It can be sprayed to virtually
any exterior stud or furred cavity, and in most cases the
wall can be closed up the same day. |

Energy Savings
Example |
|
In a series of tests,
five identical buildings were monitored for KWH usage over
an eleven month period. One building utilized sprayed
cellulose in the walls, and the other four utilized
fiberglass batt insulation. Upon conclusion, the cellulose-insulated
building saved 32% of the KWH usage of the other buildings. |
