Abstract
Fibrous insulation suitable for use in insulation cavities in buildings includes mineral fibers in an amount within the range of from about 90 to about 99 percent by weight, and organic material, in the form of organic fibers and organic particles, in an amount within the range of from about 1 to about 10 percent by weight. The mineral fibers and the organic material are integrated together so that the organic material is distributed generally uniformly among the mineral fibers. At least a majority, or about 50 percent by weight and, more preferably, a substantial amount, or about 75 percent by weight, of the organic material is in the form of organic fibers. The fibrous insulation is preferably binderless and encapsulated.
