Abstract
A loose-fill insulation product is provided which includes a dry mixture of loose-fill fiberglass and an inorganic 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.
Claims13
A method of spraying or blowing loose-fill fiberglass insulation into a vertically extending open cavity, the method comprising the steps of:
- providing the vertically extending open cavity to be insulated;
- providing loose-fill fiberglass;
- mixing the loose-fill fiberglass together with a dry inorganic adhesive powder in order to make up a loose-fill insulation mixture;
- and
- spraying or blowing the loose-fill insulation mixture together with an adhesive-activating liquid into the vertically extending open cavity so that the mixture is retained in the cavity in order to insulate the open cavity with insulation having an applied LOI percentage less than about 2.0% and a density less than or equal to about 2.5 lb./ft..sup.3.
A method of spraying a loose-fill fiberglass insulation mixture into a vertically extending open cavity to be insulated, the method comprising the steps of:
- providing loose-fill fiberglass;
- providing a dry inorganic adhesive powder;
- providing an adhesive-activating liquid;
- mixing the fiberglass together with the dry inorganic adhesive powder to form a loose-fill insulation mixture;
- and
- spraying the loose-fill insulation mixture together with the adhesive-activating liquid into the vertically extending open cavity to be insulated so that the applied insulation is retained in the vertically extending open cavity and has a density of less than or equal to about 2.5 lb./ft..sup.3.
A method of blowing loose-fill substantially non-siliconized insulating fiberglass into a substantially vertically extending open cavity, the method comprising the steps of:
- providing the substantially non-siliconized loose-fill fiberglass;
- providing an adhesive to be mixed with the substantially non-siliconized loose-fill fiberglass;
- spraying or blowing the adhesive, the substantially non-siliconized fiberglass, and a liquid into the substantially vertically extending open cavity so that the substantially non-siliconized loose-fill fiberglass is retained in the substantially vertically extending open cavity;
- and
- allowing the loose-fill fiberglass and adhesive in the open cavity to cure so that the installed insulation in the open cavity has a density of less than or equal to about 2.5 lb./ft..sup.3 and an R-value of at least about 3.15 per inch thickness.
