Why Celbar?
What can Celbar do for you?
|
|
Cool in Summer and Warm in Winter
Heat moves into, out of and through your home in four ways: by conduction (which R-Value measures), and by convection, radiation and air infiltration (none of which R-Value measures).
A superior insulation system will have a high R-Value (prevent heat transfer via conduction), will be pneumatically or spray applied, fully filling the building cavity (preventing heat loss via convection), and will be densely packed (preventing heat loss via air infiltration and radiation). Cellulose insulation meets all four of these critical performance criteria!
By comparison, the most widely used insulation material, conventional fiberglass batts, only helps prevent conduction.

Sound Control
|
|
Insulation provides more effective sound control than drywall alone. If you’ve ever been in a building that had little or no insulation, you probably noticed that you heard a lot more noise from outside than in a well-insulated building. This is because the sound transmission coefficient (STC) of an insulated building is lower. The STC is a calculation of the acoustic performance of a wall or ceiling, and a higher number is better than a lower number. Cellulose insulation has a better STC rating than either fiberglass or foam, two of the most common insulating materials. That means a building insulated with cellulose will be very quiet. |
Where do I put insulation?
The most common locations for insulation are attics and exterior walls. However, to gain the maximum impact from your insulation, it should also be installed in ceilings with unheated spaces, interior walls for improved sound control, overhangs, sun-rooms etc.

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