ABSTRACT:
A portable apparatus for blowing a chemically treated cellulose insulating material into an attic, wall cavity or wet spraying the material against a surface for insulating it. The apparatus breaks the cellulose material into small particles and, after fluffing the material, the apparatus meters and feeds the material under pressure through a hose and out through a nozzle where an operator can point the nozzle for directing the material to any desired area. Three different nozzles are used: one for attic insulation; a second for filling wall cavities; and a third for wet spraying the material against a surface for causing the material to adhere to the surface.
