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, around plumbing and electrical outlets, vent ducts, and other irregularities effectively reducing sound and heat transfer.


Thermal Control
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.
Sound Control
Commercial Projects
On a commercial level, Celbar Spray is specified to reduce sound and heat transfer between walls and floors in multi-family projects such as condominiums, retirement communities, hotels, or casinos.
