What is GreenFiber Insulation made from?
GreenFiber Insulation is a cellulose insulation that consists of 85% recycled paper, mostly recovered, post-consumer paper fiber that contains additives for fire and fungal resistance. One of the most plentiful sources of paper fiber is recycled newspaper.
Will it burn?
GreenFiber Insulation is manufactured under the Consumer Product Safety Commission (CPSC) performance criteria mandating fire safety standards. GreenFiber Insulation earns a Class 1/A fire rating and is permitted as a fire block under Section 4.4 of the International Code Council (ICC ESR-1996). The 1998 large-scale outdoor fire demonstration, conduct by the Maryland Fire & Rescue Institute, found cellulose insulation increased fire resistance by as much as 57% over fiber glass insulation.
Will it lose flame resistance over the years?
No. Accelerated aging tests (CAN/CGSB-51.60 M-90) performed on cellulose insulation have shown that there is no noticeable degradation over time. GreenFiber offers a limited lifetime warranty, which includes the permanency of the fire retardant treatment for the life of the structure.
What are the sound control capabilities of GreenFiber Insulation?
GreenFiber Insulation is effective in helping create a quieter home environment. This is especially true for airborne sound that is generated by traffic noise, airplanes, radios, televisions, and conversation. The sound control quality of GreenFiber Insulation is due to its density—approximately two to three times greater than similar fiber glass products—and its ability to fill any cavity into which it is properly installed. GreenFiber Insulation fills voids and gaps that allow for sound transmission. Where air goes, sound follows. GreenFiber Insulation has a Noise Reduction Coefficient of .90 (90% of sound energy absorbed).

What about formaldehyde, glass fibers or harmful chemicals?
GreenFiber Insulation is not manufactured with formaldehyde, asbestos or fiber glass.
Will it corrode metal?
GreenFiber Insulation meets or exceeds standard industry tests (ASTM C 739) for corrosion, performed on steel, copper and aluminum.
What effect does moisture have on GreenFiber Insulation?
Normal moisture and humidity changes have no significant effect on performance. GreenFiber Insulation retains a natural moisture level between 5% and 15% by weight. Like other insulation materials, cellulose is not recommended for use wherever there is continuous exposure to moisture and lack of drying conditions.
Can GreenFiber Insulation be installed over existing insulation?
GreenFiber Insulation is ideally suited to providing additional R-value over existing attic insulation, as it completely fills voids and gaps left open by other forms of insulation. GreenFiber Insulation can also be installed in existing uninsulated exterior walls through various methods.
Will it settle in attics or sidewalls?
GreenFiber Insulation installed in attics will settle until it reaches a stable density, as will other types of blown insulation. Coverage charts have already taken this into account. In sidewalls, GreenFiber Insulation will not settle when properly installed.
Will GreenFiber Insulation harm me if I touch it or breathe it?
GreenFiber Insulation does not itch. It is listed as a nuisance dust on the Material Safety Data Sheet, and GreenFiber recommends use of a dust mask and safety glasses during installation.
