SOUND—Our cardboard 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. Our material 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 cardboard provides superior sound transfer control demanded by building designers, owners and occupants. Cardboard 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 our monolithic application. Enjoy STC or sound control up to an STC 50 with only 2” of spray in your wall cavity.

FIRE—An amazing 2 hour load bearing wall that holds1415 pounds per stud.  UL rated this wall saves thousands of dollars as compared to conventional fire systems.  Used in commercial partition walls and between multifamily residential walls this system offers a low cost, time saving advantage to the architect, contractor or design build firm. 

Many competitors argue that because cellulose insulation is made from paper, it’s naturally more flammable than other forms of insulation. They neglect to say that cellulose insulation is treated with fire retardants, giving cellulose wall assembly an effective 1-hour fire rating.

Cellulose also meets all Federal regulations and ASTM standards for fire safety, in accordance with UL 723 and ASTM C-739-05b characteristics.

Fire Spread and Smoke Developed are two key metrics regarding how insulation will perform in a fire.

Fire Spread refers to the speed at which flames spread along the surface of the insulating material. Smoke Developed refers to the amount of smoke that is produced while the product burns. In most house fires, it’s not the flames that cause injury or death, but rather smoke inhalation. Smoke also creates confusion and can obscure fire exits.

In one study, the ratings show that cellulose insulation outperforms the competition on these two key metrics. On smoke developed, less than 400 is a passing score. In order to pass, Open Cell Foam needs an additional component to meet the requirements. Our cardboard hosts a zero (0) smoke spread rating.
