Abstract
A cellulose-based fire resistant insulation and related method for making the same. The insulation includes a plurality of superstructures that establish voids in the insulation. The insulation may be blown in place while the superstructures maintain the void portion of the insulation. The insulation is made with fiber residuals, either alone or in combination with other cellulosic materials. The method of making the insulation includes the steps of treating the cellulosic materials with a fire retardancy chemical or chemicals and creating bonds between the fibers to form the superstructures.
