Pre-cut fibrous insulation for custom fitting wall cavities of different widths

A fibrous insulation blanket pre-cut for custom fitting the insulation blanket into structural framework building cavities of different widths, comprising:

• a fibrous insulation blanket;
• the fibrous insulation blanket having a length, a width and a thickness;
• the length of the fibrous insulation blanket being at least three times the width of the fibrous insulation blanket;
• the width of the fibrous insulation blanket being substantially equal to a width of a standard cavity about fifteen inches wide;
• the fibrous insulation blanket having a first major surface and a second major surface;
• the fibrous insulation blanket having a first cut in the first major surface of the fibrous insulation blanket extending for the length of the fibrous insulation blanket;
• the first cut having a depth greater than one half of the thickness of the fibrous insulation blanket and less than the thickness of the fibrous insulation blanket;
• the fibrous insulation blanket having a second cut in the first major surface of the insulating blanket extending for the length of the fibrous insulation blanket and parallel to the first cut;
• the second cut having a depth greater than one half of the thickness of the fibrous insulation blanket and less than the thickness of the fibrous insulation blanket;
• and
• the first and second cuts dividing the fibrous insulation blanket into three sections about three and one half inches, about five inches, and about six and one half inches wide, respectively whereby the fibrous insulation blanket can be handled as a unit for insulating a cavity having a standard cavity width or easily torn apart at either the first or second cut by hand for insulating a cavity having less than a standard cavity width.

• the fibrous insulation blanket having a length, a width and a thickness;
• the length of the fibrous insulation blanket being at least three times the width of the fibrous insulation blanket;
• the width of the fibrous insulation blanket being substantially equal to the width of a standard cavity to be insulated;
• the fibrous insulation blanket having a first major surface and a second major surface;
• the fibrous insulation blanket having a first cut in the first major surface of the fibrous insulation blanket extending for the length of the fibrous insulation blanket;
• the first cut having a depth greater than one half of the thickness of the fibrous insulation blanket and less than the thickness of the fibrous insulation blanket;
• and
• a facing sheet overlying the entire second major surface of the fibrous insulation blanket and being bonded to the second major surface of the fibrous insulation blanket;
• and the facing sheet having a first perforated line therein extending for the length of the fibrous insulation blanket and aligned with the first cut in the fibrous insulation blanket whereby the fibrous insulation blanket with the facing can be handled as a unit for insulating a cavity having a standard cavity width or easily torn apart at the first cut and the aligned first perforated line by hand for insulating a cavity having less than a standard cavity width.
