Abstract
Abstract A highly flexible reflective insulation inner assembly is provided which spaces a pair of flexible reflective insulation sheets while also sealing a volume of space therebetween. To accomplish this a corrugated strip of material is mounted on its edge between the pair of flexible reflective insulation sheets all along the perimeter of the two sheets. The corrugated strip seals and spaces the two flexible sheets while allowing them to be curved and bent to conform to the shape of the more rigid inner and outer case assembly which mounts on the body to be insulated to thus provide a flexible and efficient thermal insulation inner assembly. In vertical mounting of such reflective insulation inner assemblies the height of the enclosed volume is maintained at substantially twelve inches to minimize convective heat transfer thereby.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
118 words
A reflective insulation assembly intended to be mounted on a body to be insulating comprising: a first sheet of reflective insulation; a second sheet of reflective insulation; and a corrugated strip of material mounted on its edge between said first and said second sheet of reflective insulation along the entire perimeter of said first and second sheets of reflective insulation to thereby space said first and second sheets of reflective insulation and enclose a sealed volume of space between said first and said second sheets of reflective insulation and secured to said first sheet of reflective insulation; means retaining said second sheet of reflective insulation against said corrugated trip of material and said first sheet of reflective insulation.
Claim 2
Dependent Claim
118 words
A reflective insulation assembly intended to be mounted on a body to be insulating comprising: a first sheet of reflective insulation; a second sheet of reflective insulation; and a corrugated strip of material mounted on its edge between said first and said second sheet of reflective insulation along the entire perimeter of said first and second sheets of reflective insulation to thereby space said first and second sheets of reflective insulation and enclose a sealed volume of space between said first and said second sheets of reflective insulation and secured to said first sheet of reflective insulation; means retaining said second sheet of reflective insulation against said corrugated trip of material and said first sheet of reflective insulation.
Claim 3
Dependent Claim
40 words
A reflective insulation assembly as set forth in claim 1 including means for limiting the vertical height of the volume enclosed between said first and said second sheet of reflective insulation to minimize convective heat transfer within the enclosed volume.
Claim 4
Dependent Claim
54 words
A reflective insulation assembly as set forth in claim 1 wherein said enclosure means includes a series of corrugated strips of material parallel mounted on their edges between said first and said second sheet of reflective insulation to divide the enclosed volume therebetween into separate enclosed volumes having a spacing of substantially 12 inches.
Claim 5
Dependent Claim
35 words
A reflective insulation assembly as set forth in claim 3 including an outer case assembly mounted on the body to be insulated and having said spaced first and second sheets of reflective insulation located therein.
Claim 6
Dependent Claim
34 words
A reflective insulation assembly as set forth in claim 4 wherein said outer case assembly is a substantially flat assembly and wherein said first and said second sheets of reflective insulation are substantially flat.
Claim 7
Dependent Claim
41 words
A reflective insulation assembly as set forth in claim 4 wherein said outer case assembly is substantially curved and said first and said second sheets of reflective insulation are mounted therein to conform to the curve of the outer case assembly.
Claim 8
Dependent Claim
148 words
A combination sealer and spacer assembly for reflective insulation sheets comprising: a first reflective insulation sheet; a corrugated strip of material mounted on its edge along the perimeter of said first reflective insulation sheet by a series of clips, each clip having a triangular structure extending over the height of said corrugated strip at one point along said corrugated strip and having flat leg structures extending from the base of the triangular structure fastened to said first reflective insulation sheet to thereby retain said corrugated strip to said first sheet of reflective insulation; and a second reflective insulation sheet located on said corrugated strip of material to be spaced from said first sheet of reflective insulation by said corrugated strip of material and to thereby seal a volume of space between said first and second sheets of reflective insulation within the perimeter of said corrugated strip of material.
Claim 9
Dependent Claim
148 words
A combination sealer and spacer assembly for reflective insulation sheets comprising: a first reflective insulation sheet; a corrugated strip of material mounted on its edge along the perimeter of said first reflective insulation sheet by a series of clips, each clip having a triangular structure extending over the height of said corrugated strip at one point along said corrugated strip and having flat leg structures extending from the base of the triangular structure fastened to said first reflective insulation sheet to thereby retain said corrugated strip to said first sheet of reflective insulation; and a second reflective insulation sheet located on said corrugated strip of material to be spaced from said first sheet of reflective insulation by said corrugated strip of material and to thereby seal a volume of space between said first and second sheets of reflective insulation within the perimeter of said corrugated strip of material.
Claim 10
Dependent Claim
60 words
An assembly as set forth in claim 7 including corrugated spacer means extending horizontally across said first reflective insulation sheet to provide an enclosed volume between said first and second reflective insulation sheet having a height of substantially 12 inches whenever said first and second reflective insulation sheets are mounted in a vertical manner and spaced between 1/4" and 1/2".
Claim 11
Dependent Claim
52 words
An assembly as set forth in claim 8 wherein said corrugated spacer means includes a second strip of corrugated material mounted along its edge to said first sheet of reflective insulation to be substantially 12 inches from said corrugated strip mounted along the top edge of said first sheet of reflective insulation.
