A fire-resistant, cellulose insulation and method, the cellulose insulation
including a predetermined quantity of talc to impart the desired degree of
fire-resistant characteristics to the cellulose. If desired, limited
quantities of boron compounds can be added with the talc. The method
includes directing ground cellulose from the primary grinding stage into a
surge bin to accommodate metering the talc with the cellulose to thereby
assure the appropriate distribution ratio of talc in the cellulose.
