ABSTRACT:
The present invention, in certain embodiments discloses an insulation composition including polyvinyl alcohol cooked without an acidic medium and cellulose fibers combined with an acidic medium for spray-on insulation. In certain embodiments cellulose fibers and acidic solids are ground together. In one aspect the acidic medium is solid boric acid. In another aspect liquid boric acid is sprayed onto the fibers Systems are disclosed for introducing the fiber acidic composition into a first hose of a spray nozzle while introducing polyvinyl alcohol into a second hose of the spray nozzle. In another aspect an acrylic resin is mixed with the polyvinyl alcohol.
