Celbar meets all applicable federal regulations and ASTM standards for fire safety, in accordance with UL 723 and ASTM C-739-05b characteristics.
Flame 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 fire resistant insulation outperforms the competition on these two key metrics. On smoke developed, less than 450 is a passing score. In order to pass, Open Cell Foam needs an additional component to meet the requirements, such as Ure-k, a true 15 minute thermal barrier.
|Celbar Fire Resistant Insulation||15||0|
|Open Cell Foam||25||<450|
Celbar is UL Rated for Flame Spread and Smoke Developed with the highest available rating. A specially formulated borate compound gives Celbar fire resistant insulation a Class 1 fire rating. Additionally, Celbar provides a barrier that resists penetration by fire.
