Cellulose's highly efficient thermal barrier actually repels intense heat. It outperforms fiberglass by forming a barrier to protect other, more combustible construction materials. And Cellulose's Class 1 fire rating meets or exceeds all requirements of local and national building codes. When it comes to fire safety, Cellulose is one of the safest insulation materials you can use.

The same non-toxic, 100% borate chemical that gives Cellulose, its fire retardant qualities, also acts as a fungicide helping control mold and mildew. Even though this chemical is completely harmless, insects have an aversion to it and move to other habitation.
