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 which 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 reductions, 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.
Laboratory tests have proven that Celbar produces
significantly higher STC values than other identically constructed wall
systems.

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
completely fills cavities around pipes and obstructions, and
covers cracks. Celbar minimizes air
infiltration and forms 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 was insulated with sprayed
cellulose in the walls, and the other four were insulated with
fiberglass batts. Upon conclusion of the tests, the
cellulose-insulated building saved 32% of the KWH usage of the other
buildings.
