Abstract
The present invention provides thermal insulation products such as loose fill, bats and boards, such as duct boards and duct liner. The insulation products include randomly distributed inorganic fibers which are supplemented with at least about five weight percent microspheres, macrospheres, or both, preferably include hollow microspheres, which boost the insulation value of the fiberglass thermal insulation by at least about 0.5 R.
