ABSTRACT:
A loose-fill insulation product is provided which includes a dry mixture of loose-fill fiberglass and an inorganic (being composed of matter other than plant or animal) adhesive in the form of a redispersible powder. During application, the dry loose-fill mixture is coated with a liquid (e.g. water) so as to activate the adhesive. Thereafter, the loose-fill mixture with activated adhesive is blown or sprayed into a cavity (open or closed) so as to insulate same. According to certain embodiments, this mixture may be blown into open attic areas so as to insulate same and reduce the movement of loose-fill insulation. It has been found that the redispersible powder (RP) dry adhesive mixes more uniformly within the dry mixture and clings better to the glass fibers when the mixture is substantially free of anti-static material. In certain embodiments, a color dye is provided in the mixture, and is activated upon installation.
