Abstract
Abstract A metal strapping band to support flexible insulation within a wall cavity between spaced-apart wall studs, which strapping band comprises an elongated, metal strapping band having a plurality of uniformly spaced-apart lines of weakness therein extending from and adjacent at least one edge thereof, to define a plurality of defined tab elements in the plane of the band, which tab elements may be bent outwardly from the plane of the metal band, to form a support for flexible insulation to be secured within the wall cavity between the wall studs, the insulation supported by securing the metal strapping band to and across the wall studs, and bending outwardly the defined tab elements and impaling the flexible sheet material on the bent tab elements.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
194 words
A method of supporting insulation in an upright position in a wall cavity between spaced-apart wall studs which define a plurality of wall cavities therebetween, which method comprises: (a) securing an elongated metal strapping band spanning the plurality of wall cavities having a one and other end in a generally horizontal position to one face of the wall studs and extending therebetween, the one or other end extending beyond at least one wall stud, the metal strapping band characterized by having a plurality of uniformly spaced-apart lines of weakness thereof extending from and adjacent at least one edge thereof and extending between the one and other end, to define a plurality of defined tab elements in the plane of the strapping band and defined by the lines of weakness; (b) bending at least one of the defined tab elements from the edge of the strapping band along the lines of weakness and extending the tab elements generally perpendicular from the plane of the metal strapping band and into at least one of the wall cavities; and (c) supporting insulation in the wall cavity by impaling the insulation upon the outwardly extended, defined tab elements.
Claim 2
Independent Claim
194 words
A method of supporting insulation in an upright position in a wall cavity between spaced-apart wall studs which define a plurality of wall cavities therebetween, which method comprises: (a) securing an elongated metal strapping band spanning the plurality of wall cavities having a one and other end in a generally horizontal position to one face of the wall studs and extending therebetween, the one or other end extending beyond at least one wall stud, the metal strapping band characterized by having a plurality of uniformly spaced-apart lines of weakness thereof extending from and adjacent at least one edge thereof and extending between the one and other end, to define a plurality of defined tab elements in the plane of the strapping band and defined by the lines of weakness; (b) bending at least one of the defined tab elements from the edge of the strapping band along the lines of weakness and extending the tab elements generally perpendicular from the plane of the metal strapping band and into at least one of the wall cavities; and (c) supporting insulation in the wall cavity by impaling the insulation upon the outwardly extended, defined tab elements.
Claim 3
Dependent Claim
18 words
The method of claim 1 wherein the defined tab elements comprise generally angular tabs having a sharp point.
Claim 4
Dependent Claim
37 words
The method of claim 1 wherein the wall studs comprise metal wall studs having a generally U-channel sectional form, and wherein at least one of the tab elements is secured about the one edge of the form.
Claim 5
Dependent Claim
13 words
The method of claim 1 wherein the insulation comprises flexible fiberglass layer material.
Claim 6
Dependent Claim
24 words
The method of claim 1 which includes bending outwardly at least two of the tab elements in each wall cavity, to support the insulation.
Claim 7
Dependent Claim
83 words
The method of claim 1 which includes securing the metal strapping band in a generally horizontal position, extending across a plurality of the wall cavities, wherein the wall studs comprise metal studs having an open, U-shaped channel, which method includes bending at least one tab element along the lines of weakness and about a lip of the open, U-shaped channel of the metal studding, to secure the metal strapping band in a generally horizontal position to the U-shaped channel of the metal studs.
Claim 8
Dependent Claim
33 words
The method of claim 1 which includes placing a plurality of metal strapping bands across the wall studs at defined horizontal positions, extending between the top and the bottom of the wall stud.
Claim 9
Dependent Claim
33 words
The method of claim 1 wherein the lines of weakness comprise a plurality of generally angular, parallel lines of weakness extending inwardly up to about 50% of the width of the strapping band.
Claim 10
Dependent Claim
38 words
The method of claim 1 wherein the lines of weakness are characterized by a series of perforations which permit the defined tab elements to be bent easily by the installer from the plane of the metal strapping band.
Claim 11
Dependent Claim
47 words
The method of claim 1 wherein the defined tab elements to be bent from the metal strapping band are generally triangular in shape, with the lines of weakness extending at an angle of from about 30 to 45 degrees inwardly from the edge of the strapping band.
Claim 12
Dependent Claim
174 words
A building comprising: (a) a plurality of generally vertical, metal, U-channel wall studs having lip elements to define the U-channel and the wall studs, and to define a plurality of wall cavities between each pair of wall studs; (b) at least one metal strapping band extending generally horizontally across more than one wall cavity, the metal strapping band characterized by a plurality of defined tab elements extending outwardly and generally perpendicular from the strapping band and into at least one wall cavity defined by the wall studs, the defined tab elements extending from the one of the outer edges of the metal strapping band; (c) the metal strapping band retained in a generally horizontal position across the metal wall studs by at least one tab element of the metal strapping band bent around one of the lip elements of the U-channel wall studs; and (d) insulation in the wall cavity, the insulation retained in an upright position by being impaled on at least one of the outwardly bent tab elements within the wall cavity.
