FIBER INSULATION BLANKET AND METHOD OF MANUFACTURE
A fiber blanket formed with a blend of constituent fibers is disclosed. In one disclosed embodiment, a cellulose fiber blanket is formed having a blend of cellulose fibers comprising approximately 85-90% by weight cellulose, resilient fibers comprising approximately 10% by weight, and the balance being adhesive plastic fibers. The fibers are then formed into a blanket having an R-value at least 4.0 per inch.
