  • Enhanced cellulose loose-fill insulation
    Patent number: 5910367
    Abstract: A loose-fill cellulose insulation having improved density can be achieved by intermingling the cellulose fibers with natural textile fibers. The textile fibers tend to maintain the spacing between the cellulose fibers, which decreases the density and minimizes settling, of the resulting insulation.
