Cellulose has many advantages over fiberglass; it has a lifetime warranty, is permanently non-flammable and 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 10-inches of thickness, whereas fiberglass needs be about 12-inches thick to achieve the same performance, this makes cellulose far more effective per inch.
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. You can actually hold a match or torch to the product and it will not burn!
An additional benefit of the cellulose being treated with borate is that its resistant to insects, rodents, molds, mildew and fungus. Cellulose is also very earth-friendly in that it is made from almost entirely recycled products. Cellulose also has excellent sound-reducing qualities too, homeowners frequently report a quieter home after it’s insulated.
