What is cellulose made of?
Cellulose is primarily made of newspaper and fire retardants. The fire retardants include boric acid, borates and ammonia sulfate. Depending on the manufacturer the amount of each fire retardant differs. The fire retardant ingredients also control mold and rodents. Cellulose’s ability to control moisture and air flow better then fiberglass make it Insta Insulation’s preferred choice for all attic insulation installs.
