CELLULOSE INSULATION
Cellulose is only available as a loose-fill (blown) material. We consider it the most effective, efficient, longest-lasting and safest material you can use. Cellulose has many advantages over fiberglass; it is nonflammable, resistant to rodents, insects and mold. It also has soundproofing qualities and does not itch. Best of all, cellulose is non-toxic, safe and environmentally friendly.
Cellulose has many advantages over fiberglass. Cellulose attains an R-38 rating with approximately 11-12inches of thickness, whereas fiberglass at the same R 38 takes 14-15 inches of thick thickness.
Cellulose is made from reconstituted wood fiber product, which includes newspaper, cardboard and other wood related products. While some would imagine this to be flammable, the cellulose is treated with borate to be permanently non-flammable. Cellulose carries an ASTM Class 1 rating and meets specifications set by federal, state and local building authorities for being non-flammable.
