View Two Amazing Celbar Videos

Celbar is made from only high quality recycled paper products to create a superior sound trapping insulation when used in cavity wall applications.

Celbar is extremely effective at eliminating noise transfer from one room to another by absorbing significant sound waves entering the product. The STC ratings (Sound Transmission Coefficient) of Celbar can reach 58 depending on wall configuration and construction. An STC rating of 50 is considered inaudible to the human ear. (RATING CHART) As you can see below, Celbar stands out against competing products and their ability to control noise transfer.

Celbar has an R-value of 3.8 per inch allowing you to design exterior wall systems with higher total R-values. An R-19 wall system can be achieved using a 6" stud cavity. However, R-value alone is not the only measure of a product's thermal effectiveness. It is documented that up to 65% of heat loss is through seams and gaps in mechanical insulation methods. (R You Getting What Your're Paying For) To obtain maximum thermal efficiency, air infiltration must be minimized. Sprayed in place, Celbar conforms to any substrate, around pipes, obstructions, and over cracks, reducing air infiltration and forming a highly efficient and effective thermal barrier. It can be sprayed to virtually any exterior stud or furred cavity.

Celbar has integrated chemical components that will not allow mold or mildew to occur, protects against insect infestation, and won't provide homes for rodents like most other insulations. Celbar carries a CLASS I Fire rating. (Fire Test Video) (Fire Rating)
