Abstract
Abstract A novel and highly efficient insulating wall structure for a building comprises a generally closed wall with a top venting structure only. The wall structure generally comprises two substantially moisture and air impervious barriers spaced from each other by intervening framing members, a bottom substantially moisture-and-air impervious closure sealing the bottom of said barriers and a venting structure locating only at the top of said wall to release water vapor from the interior of said wall.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
90 words
A top-vented, insulating wall in a building structure comprising spaced vertical framing members and interior and exterior face-forming layers, a first substantially moisture- and air-impervious barrier located on one side of said framing members, a second substantially moisture- and air-impervious barrier located on the other side of said framing members, a substantially moisture- and air-impervious closure substantially sealing said barriers at the bottom of said wall and a venting structure located only at the top of said wall to permit release of water vapor from the interior of said wall.
Claim 2
Dependent Claim
90 words
A top-vented, insulating wall in a building structure comprising spaced vertical framing members and interior and exterior face-forming layers, a first substantially moisture- and air-impervious barrier located on one side of said framing members, a second substantially moisture- and air-impervious barrier located on the other side of said framing members, a substantially moisture- and air-impervious closure substantially sealing said barriers at the bottom of said wall and a venting structure located only at the top of said wall to permit release of water vapor from the interior of said wall.
Claim 3
Dependent Claim
21 words
A wall as recited in claim 1 in which one of said substantially moisture- and air-impervious barriers is thermal insulation board.
Claim 4
Dependent Claim
19 words
A wall as recited in claim 2 in which said thermal insulation board is a plastic foam insulation material.
Claim 5
Dependent Claim
24 words
A wall as recited in claim 2 in which said thermal insulation board has a major surface covered with a moisture- and air-impervious sheet.
Claim 6
Dependent Claim
24 words
A wall as recited in claim 2 in which both sides of said thermal insulation board are covered with a moisture- and air-impervious sheet.
Claim 7
Dependent Claim
20 words
A wall as recited in claim 1 in which one of said moisture- and air-impervious barriers is a flexible sheet.
Claim 8
Dependent Claim
13 words
A wall as recited in claim 6 which said flexible sheet is polyethylene.
Claim 9
Dependent Claim
16 words
A wall as recited in claim 6 in which said flexible sheet is supported aluminum foil.
Claim 10
Dependent Claim
21 words
A wall as recited in claim 1 in which one of said moisture- and air-impervious barriers is foil laminated gypsum wallboard.
Claim 11
Dependent Claim
27 words
A wall as recited in claim 1 in which said wall has cavities between said framing members and said cavities are substantially filled with thermal insulation material.
Claim 12
Dependent Claim
34 words
A wall as recited in claim 10 wherein said thermal insulation material is thermal insulation granules, mineral fiber thermal insulation, cellulose fill material, foam plastic material, polyurethane foam, polyisocyanurate foam, or urea formaldehyde foam.
Claim 13
Dependent Claim
31 words
A wall as recited in claim 1 in which said venting structure comprises a corrugated member located between one of the said substantially moisture- and air-impervious barriers and said framing members.
Claim 14
Dependent Claim
22 words
A wall as recited in claim 12 in which said corrugated member is high density polyethylene, polypropylene, rigid polyvinyl chloride or metal.
Claim 15
Dependent Claim
