Abstract:
1. A method of making a thermal insulation product capable of being blown into place, comprising: a) forming a thermal insulation product precursor by disposing onto a receiving surface, a combination consisting of randomly distributed glass fibers being mixed with air, and based on a weight percent of the glass fibers, at least about 5-500 wt. % of calcium acetate or cupric carbonate, about 5 wt. %-500 wt. % heat-expandable hollow microspheres in dry or slurry form and containing a heat expandable gas, and a binder for adhering said calcium acetate or cupric carbonate and said hollow microspheres to corresponding said glass fibers; (b) adding a binder to the precursor for adhering said calcium acetate or cupric carbonate to the hollow microspheres and to corresponding glass fibers; (c) heating said thermal insulation product precursor to expand at least a portion of said unexpanded hollow microspheres to increase their size; and (d) cooling said thermal insulation product precursor to form expanded hollow microspheres combined with said fibers to said calcium acetate or said cupric carbonate.
