More about Blown-in Cellulose Insulation

Blown-in cellulose insulation is used in residential and some commercial buildings, as part of new construction or as part of retrofit projects. Cellulose insulation is a mixture of newsprint (the vast majority from post-consumer sources), flame retardants, and oils which help to control dust. The cellulose insulation is blown into wall and floor cavities until the manufacturer-recommended density or thickness is achieved. "Dense-pack" cellulose, typically used in wall applications to prevent settling, is a more dense packing of the same product. The composition of newspaper for this assessment is assumed to be that of a standard black ink used in offset lithographic printing, on a 100% recycled newsprint substrate. Newsprint printed with colored inks would have a variety of additional hazards, depending on the pigments used; these hazards are not captured here.
