Today, there is a growing public concern for reducing damage to our environment and dependence on fossil fuels. GreenFiber responds to this concern by offering insulation products endowed with multiple environmental benefits produced in a virtually waste-free manufacturing process. GreenFiber manufactures GreenFiber Insulation for use in attics, floors, and walls of residential new construction and re-insulation applications. GreenFiber provides outstanding thermal performance, fire-resistance and sound control. GreenFiber's Insulation products provide a barrier against air infiltration by filling gaps and voids. Consisting of 85% recycled content (SCS certified), GreenFiber Insulation is specially treated for flame resistance.

Benefits

Protect Your Home—Effectively
GreenFiber Insulation forms a monolithic blanket of protection—blocking air infiltration and convection currents that are both primary causes of energy loss.

Imagine heating your home in the winter or cooling your home in the summer…and then leaving the front door open. If you add up all the possible air leaks in a typical home—cracks at the joints in the frame; small spaces around windows and doors; areas around pipes, ducts, vents and electrical outlets—it can have the same effect as an open door or window. When batt insulation is cut or forced to fit around irregular shapes, gaps can result that enable air to pass right through. That's called air infiltration or air leakage, and it can account for as much as a third of heat loss in a home.

GreenFiber Insulation, however, is blown or sprayed into place, preventing gaps and stopping air leaks better because of the way it's applied. And GreenFiber Insulation is two to three times more dense than comparable fiberglass batts. That means heated air can't transfer through dense GreenFiber Insulation as easily as it does through typically installed fiberglass.

Installing insulation properly is the first step in making sure your home is more comfortable and energy efficient.

One important component of any home is the pressure barrier. The pressure barrier is defined as a continuous plane that separates the conditioned area of the building from the unconditioned area. Drywall is the most common pressure barrier in construction today.

Insulation should always be in direct contact with the pressure barrier of the building. This standard of effective thermal installation means that the insulation has no gaps, no voids, no compression, no misalignment and no wind intrusion.

Insulate Against the Seasons
The R-value of GreenFiber Insulation, or its ability to stop heat transfer, remains consistent through a greater temperature and application range than that of loose-fill fiberglass, keeping heat in during the winter, and out during the summer.

The R-value of GreenFiber GreenFiber Insulation, or its ability to stop heat transfer, remains consistent through a greater temperature and application range, keeping heat in during the winter, and out during the summer.

The U.S. Federal Trade Commission developed an insulation rating mechanism to help end the false and misleading claims about insulation that once abounded. Called R-value, this rating is based on a laboratory measurement, the R-factor, which reflects a material's ability to stop or slow heat transfer. When you're shopping for insulation or talking to your builder, understanding R-value can help you make intelligent choices about insulation. But, in the real world environment of your side walls and attic, there are variables that change how that insulation will perform.

For one thing, R-value changes with extreme temperatures. So attic insulation rated R-38 will perform at a different R-value at 20°F below zero. Why is this an important distinction? The effective R-values of both GreenFiber Insulation and fiberglass may change under very cold temperatures.

While loose-fill fiberglass can lose as much as half its R-value at 20°F below zero, GreenFiber Insulation continues to perform at a more consistent R-value.

So R-value is a useful measurement of thermal resistance, but it's important to remember that R-value is just one piece of the equation. If a house isn't properly sealed and there are gaps in the insulation, a high R-value isn't going to keep that home comfortable. Heat seeks cold spots in much the same way that water runs down a drain, or rain finds its way to a hole in the roof. It doesn't matter if the rest of the roof is performing to specification if water finds the one hole. Because it forms a seamless protective blanket, GreenFiber Insulation effectively fills those gaps.

Insulate Your House and Preserve Your PlanetGreenFiber Insulation can increase a wall's fire resistance by 22-57%. Cellulose insulation is non-toxic, and GreenFiber guarantees its products for the life of your house.

Make Your Home Safe
GreenFiber Insulation has been proven to increase a wall's fire resistance 22-57% and exceeds the tough fire safety standards set by the Consumer Product Safety Commission. 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%. Oak Ridge National Laboratory, Underwriters Laboratory and the U.S. Department of Energy have all documented the permanency of fire retardants in cellulose insulation.

The boric acid flame retardant used in GreenFiber Insulation is infused in the natural fibers of the cellulose. During a fire, the retardant melts and holds 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 GreenFiber Insulation restricts the amount of oxygen available to support combustion.

GreenFiber Insulation has a Class 1/A rating (FSC 25) for flame spread, and a smoke development rating of less than 50 when tested in accordance with ASTM E84. Because of the fire retardant application, GreenFiber Insulation has been proven more effective in actual fire situations in maintaining the structural members of a home.

GreenFiber Insulation lasts
GreenFiber Insulation has been tested by Underwriter's Laboratory according to ASTM standard C739 to be non-corrosive to steel, copper and aluminum, as well as resistant to fungi. GreenFiber guarantees its products for the life of the structure. If installed according to manufacturer's instructions, the insulation will be free from defects and will not deteriorate under normal and proper use.

The GreenFiber Commitment
We firmly believe that no other insulation manufacturer can match our commitment to our product. We guarantee that GreenFiber Insulation, properly installed, will retain its thermal resistance, fire retardant and non-corrosive characteristics; provide sound control; and continue to meet current national building code standards for the life of the structure.

Bring the Smarter Insulation to Your House
Install GreenFiber® loose-fill attic insulation yourself, or have stabilized insulation installed by a GreenFiber Insulation professional.

GreenFiber Insulation may be used in walls and attics of residential or commercial structures. It may be used in cathedral or flat ceilings, crawl spaces, basements and as insulation under floors. GreenFiber Insulation may be blown in horizontal applications such as attics and crawl spaces, and professionally sprayed into wall cavities and attics in new construction.

Product Certifications

SCS (Scientific Certification Systems)
SCS provides material content certification assessment services to manufacturers offering products made from recycled or biodegradable materials. Green Fiber is proud to have earned this important certification for its insulation products. Green Fiber insulation contains a mix of pre- and post consumer recycled materials, which are defined by ISO as follows:

Pre-Consumer Material Pre-consumer material is often defined as material that has been diverted from the waste stream during a manufacturing process. Materials generated in a process and capable of being reclaimed within the same process (such as rework, regrind or scrap) are excluded.

Post-Consumer Material Post-consumer material is generated by households or by commercial, industrial and institutional facilities in their role as end-users of a product that can no longer be used for its intended purpose.
