Certain example embodiments of this invention relate to insulation (e.g., loose-fill insulation which may be blown into attics, wall cavities, or the like) including a mixture of fiberglass and cellulose. In certain example embodiments, the insulation mixture comprises from 15-60% cellulose, more preferably from 20-50% cellulose, and most preferably from 25-45% cellulose (with substantially the remainder of the insulation be made up of fiberglass). Example advantages include improved radiant barrier properties and thus improve R-values/inch.

Insulation with mixture of fiberglass and cellulose

A system and method are provided for insulating a vertically extending wall (e.g., concrete wall). First and second supports are first attached to the vertical wall at respective first and second vertically spaced locations (e.g., proximate the top and bottom of the wall). After the supports have been attached to the wall, a blanket(s) of rolled fiberglass insulation (e.g., metal building insulation) is attached to the wall between the first and second supports. Then, a flexible sheet of vapor retarder is attached to protruding portions of the first and second supports so as to cover the blanket(s) of fiberglass insulation thereby causing the blanket of fiberglass insulation to be partially or fully hidden from view and retained in the cavity defined between the vertical wall and the vapor retarder.

System for insulating vertical wall

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.

Apparatus for impregnating surfaces, including edge surfaces, of fiberglass insulation batts with synthetic fibers, comprising a conveyor for advancing the batts in a common direction and, initially, in a side-by-side orientation. Separators thereafter interrupt the side-by-side orientation, exposing the edges of the batts. Extrusion heads located in the area of side edge exposure impregnate the exposed edges with synthetic fibers while other extruder heads apply synthetic fibers to one or optionally both of the top and bottom surfaces.

Method of installing insulation

A method of directing extruded synthetic fibers toward at least one surface of a mineral fiber insulation batt, and corresponding apparatus and resulting product. In certain embodiments, a row of extrusion heads is provided for directing extruded synthetic fibers (e.g. fibers including ethyl vinyl acetate or EVA) toward a surface(s) of the batt(s) to be impregnated with same. Optionally, extrusion heads may be provided all around the batts so as to impregnate substantially all surfaces thereof with the extruded synthetic fibers. As the fibers exit the heads, they are hit with pressurized heated air streams which cause them to go into an insipid spin which increases directional tensile strength of the resulting batt in all directions. In certain embodiments, every other batt of a plurality of batts passes over an elongated member which extends over top of the conveyor in order to more efficiently impregnate edge surfaces of the batts.

Method of impregnating a mineral fiber insulation batt with extruded

A method of manufacturing/making mineral fiber (e.g. fiberglass) thermal insulation batt is disclosed wherein a base mineral fiber layer is impregnated with a two-layer layering system so as to produce a batt which is substantially vapor impermeable with a perm vapor rating less than about one. The first layer of the layering system is of a low melt material while the second layer is of a high melt material, the first layer being sandwiched between the base insulating layer and the second layer, and functioning to bond the layering system to the base. In certain embodiments, the first layer includes quick blooming ethyl vinyl acetate (e.g. from about 10-25% by weight) and a low density (e.g. 22-26 lbs. per cubic foot) polyethylene, and the second layer includes high density (e.g. 28-38 lbs. per cubic foot) polyethylene. The resulting insulation batt is vapor impermeable, less susceptible to cold-crack, easier to manufacture, fire retardant, more durable, and easier to handle.

Mineral fiber insulation batt impregnated with coextruded polymer

A spray-on inorganic (e.g. fiberglass) insulation method and product with a low density and high R-value are disclosed. Loose-fill fiberglass is coated with a non-foaming liquid and thereafter blown or sprayed into a cavity such as a vertically extending open stud-defined wall cavity. After sticking in the cavity, the insulation is rolled to further pack it into the cavity and thereafter allowed to cure.
