Abstract
Abstract A thermal insulation batt is provided which is comprised of a layer of bulk thermal insulation material; a vapor impervious thermoplastic facing sheet adhesively bonded to the layer of insulation material; paper tabs containing a fold line securely attached along each of longitudinal sides of the facing sheet or by having dual foldable paper strips enclosed within a folded back portion of the facing sheet so as to provide a deadfold characteristic for the tabs. The insulation batts are conveniently packaged with the dual tabs folded downwardly adjacent the facing sheet, and at installation the dual tabs are folded outwardly without snapback and are attached onto spaced apart structure members such as studs of a wall.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
181 words
A thermal insulation batt comprised in combination of: a. an elongated insulation layer comprised of a low density insulation material, said layer having a predetermined width, a face surface, a back surface, and a first and second opposing longitudinal edges b. an elongated facing sheet of at least about said predetermined width, said facing sheet being formed from a water vapor impervious film of a thermoplastic material and being adhesively secured to and covering the face surface of the insulation layer c. first and second tab members being attached to the facing sheet in alignment with the respective first and second longitudinal edges of the insulation strip, each of said tab members, including an elongated paper strip containing a fold line adjacent to the longitudinal edge of the insulation layer and having deadfold characteristics sufficient for each tab member to remain in either a flat or folded back position so as to facilitate packaging of the thermal insulation and its subsequent installation by installing the tab members on supporting members, said elongated paper strips being substantially enclosed within said thermoplastic material.
Claim 2
Dependent Claim
181 words

Claim 3
Dependent Claim
51 words
The thermal insulation batt according to claim 1, wherein said dual members are each bonded onto the paper strip adhesively bonded along one longitudinal edge of said facing sheet so that the paper strip can be folded along the fold line located adjacent the longitudinal edges of the insulation material layer.
Claim 4
Dependent Claim
54 words
The thermal insulation batt according to claim 1, wherein said dual members are formed by a double thickness of the facing sheet which is folded back upon itself so as to enclose the elongated paper strip, wherein the fold line is located in the paper strip adjacent the longitudinal edges of the insulation strip.
Claim 5
Dependent Claim
21 words
The thermal insulation batt according to claim 1, wherein said facing sheet is made of polyethylene, polycarbonate, or polyethylene terephalate film.
Claim 6
Dependent Claim
17 words
The thermal insulation batt according to claim 1, wherein said paper strip has thickness of 0.030-0.050 inch.
Claim 7
Dependent Claim
24 words
The thermal insulation batt according to claim 2, wherein each said paper strip overlaps the facing sheet by a distance of about 0.25-0.5 inch.
Claim 8
Dependent Claim
21 words
The thermal insulation batt according to claim 3, wherein the folded facing sheet overlaps the insulation strip by about 0.25-0.5 inch.
