Cellulose is only available as lose-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 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-30 rating with 8.1 inches of thickness, whereas fiberglass need to be about 12-inches thick to achieve the same performance, this makes cellulose far more effective per inch. Unlike fiberglass, cellulose has no hazard/warning labels. The product is rigorously tested and approved by the Consumer Products Safety Commission, OSHA and the Underwriters Laboratories, UL label.
An additional benefit of the cellulose being treated with borate is that it is 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.
Fiberglass is available in two forms; as battling (rolled) or as loose-fill (blown) material. Many homeowners typically feel they want rolled insulation, but once they do the research they find otherwise. Fiberglass insulation, whether rolled or blown, has several negative characteristics of significant concern.
Fiberglass is glass fibers; the fibers are very small, rigid and sharp. On account of this, all fiberglass products have a hazard/warning label on them clearly relating to the danger of cancer, upper respiratory irritation, and other related illness.
Blown fiberglass is known for settling and packing after it’s installed. Much like cotton candy that it resembles, the very nature of blowing Fiberglass tends to fluff the material up, the product then settles over time. The rolled fiberglass minimizes the fluffing-effect, but the rolled-in application by its nature is several strips that run between the ceiling joists. It doesn’t seal over the top of the framing and has a compromised fit around the plumbing, piping and conduit that runs throughout the attic, so while the rolled Fiberglass won’t settle and pack as much, it’s a compromised fit to begin with.
Fiberglass does not have any insect or termite resistant qualities; in fact, fiberglass makes a splendid home for rodents and vermin. Quite often we find evidence of rats and mice living in the fiberglass. Given some moisture, fiberglass also provides an excellent media for mold & mildew to grow and foster. By comparison, Cellulose is mold, mildew, and fungal resistant, as well as rodent and insect resistant.
