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.
Claims6
A loose fill insulating material consisting essentially of cellulose fiber and about from 0.5% to 40.0% by weight of natural textile fiber in the form of individual fibers or small clumps of fibers, and optionally at least one fire retardant material.
