In laboratory fire resistance tests of wall assemblies and full-scale building demonstrations, structures with GreenFiber insulation out performed fiberglass and uninsulated structures by 22-57% (see video). A low-toxic boric acid flame retardant is added to GreenFiber, which during a fire, make the retardant melt and hold the heat until the cellulose fibers char. The cellulose then becomes a layer of carbon protection, because the charred fibers won't burn. The density of GreenFiber insulation prevents the passage of flames and hot gasses, so fire does not spread as readily into GreenFiber installed walls or ceilings, and it restricts the amount of oxygen available to support combustion.
GreenFiber is free from formaldehyde, asbestos, or fiberglass. GreenFiber helps protect structures from moisture buildup due to its natural ability to handle moisture. GreenFiber insulation has a Noise Reduction Coefficient of 0.90 (90% of sound energy absorbed). It is so effective at keeping outside noises out, that it is used as an enhanced sound control material for homes located in airport flight paths.

Recycled paper is mostly post-consumer and regionally sourced from curbside and school collection programs. Regional manufacturing means more local jobs and less pollution associated with transportation.
on the planet
GreenFiber Insulation is a non-toxic natural product made from 85% recycled paper fiber, reducing landfill waste. Each 40 sq. ft. bag contains the equivalent of about 46 Sunday newspapers. GreenFiber uses 10 times less energy to manufacture than fiberglass and is processed by electrically-driven mills that consume relatively little energy when operating. Additionally, no waste water, hazardous waste or toxic air emissions are released during the manufacturing process.
