Green Fiber Recycled cellulose blown in insulation

Share This Page

This Green Fiber insulation is made from pre-consumer recycled newspapers and phone books and uses natural borates as a fire retardant, mold prohibitor and pest repellent.  This insulation is blown in dry and can be layered on top of existing attic insulation.  Most of the heat gain and loss happens through the ceiling.  By insulating your ceiling to an R40 to R60 rating you can have considerable savings on your heating and cooling bills.  It can also be blown into existing walls and even used in walls during new construction with an insulation wrap stretched between the studs and stapled in place.
