Wall Cavity Insulation

CSI: 07 21 00 • 07 21 23

Celbar is a versatile spray-applied cellulose insulation used in walls, floor/ceiling cavities, and attics for thermal and sound control in residential and commercial projects. Made from 80% Recycled paper, Celbar provides designers and homeowners with a naturally safe and sustainable building solution at an affordable cost.

The Natural Choice

The attic blown insulation is manufactured from high-quality recycled paper blended with natural fire retardants to produce a Class A, Class One fire-rated insulation that is both environmentally friendly and highly effective. Celbar’s spray-applied application forms a uniform coating, sealing cracks, voids, or gaps in the wallboard and around plumbing, electrical outlets, vent ducts, and other irregularities, effectively reducing sound and heat transfer.

THERMAL CONTROL

With an R-value up to 3.7 per inch, Celbar 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, greatly reducing air infiltration and resulting in exceptionally low heat-loss characteristics. Celbar can be sprayed to virtually any exterior stud or furred cavity, and in most cases, the wall can be closed up the same day.

Celbar Spray: R-Value: 3.7 per inch
Celbar Loosefill: R-Value: 3.6 per inch

SoUND CONTROL

Celbar provides superior sound transfer control demanded by building designers, owners, and occupants. Additionally, Celbar assemblies tend to perform closer to lab-tested STC ratings in the field over alternative insulation systems due to the complete coverage and sealing action of Celbar.
