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.
The base system and results are as indicated in the table on this screen.
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.
