Abstract
Abstract This invention relates to a flexible compressible sealing profile having thermal insulating properties for use in cavity wall construction. This profile comprises essentially an L-shaped cross-section, which is adapted to be compression fit into the cavity wall. The profile can be utilized as both the top and bottom of cavity walls, as well as around doors and windows in order to prevent convectional heat losses from occurring.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
137 words
An elongate cavity sealing profile comprised of a flexible compressible synthetic foam of polyethylene, polypropylene, polyurethane, ethylene, vinyl acetate, polyvinyl chloride, or polystyrene having thermal insulating properties wherein the sealing profile is characterized by having a longitudinal horizontal limb having an outer longitudinal face, an inner longitudinal surface, and a longitudinal edge; and a longitudinal vertical limb having an outer longitudinal face, an inner longitudinal face, and a longitudinal top face; wherein the vertical longitudinal limb and the horizontal longitudinal limb are integrated to form a substantially L-shaped cross-section, wherein the longitudinal horizontal limb and the longitudinal vertical limb have sufficient thickness to demonstrate insulating properties, wherein the cavity sealing profile is adapted to fit against the butt end of an insulating board and to prevent the circulation of air via natural convection around the insulating board.
Claim 2
Dependent Claim
137 words
An elongate cavity sealing profile comprised of a flexible compressible synthetic foam of polyethylene, polypropylene, polyurethane, ethylene, vinyl acetate, polyvinyl chloride, or polystyrene having thermal insulating properties wherein the sealing profile is characterized by having a longitudinal horizontal limb having an outer longitudinal face, an inner longitudinal surface, and a longitudinal edge; and a longitudinal vertical limb having an outer longitudinal face, an inner longitudinal face, and a longitudinal top face; wherein the vertical longitudinal limb and the horizontal longitudinal limb are integrated to form a substantially L-shaped cross-section, wherein the longitudinal horizontal limb and the longitudinal vertical limb have sufficient thickness to demonstrate insulating properties, wherein the cavity sealing profile is adapted to fit against the butt end of an insulating board and to prevent the circulation of air via natural convection around the insulating board.
Claim 3
Dependent Claim
106 words
An elongate cavity sealing profile comprised of a flexible compressible synthetic foam of polyethylene, polypropylene, polyurethane, ethylene, vinyl acetate, polyvinyl chloride, or polystyrene having thermal insulating properties wherein the sealing profile is characterized by having a longitudinal horizontal limb having an outer longitudinal face, an inner longitudinal surface, and a longitudinal edge; and a longitudinal vertical limb having an outer longitudinal face, an inner longitudinal face, and a longitudinal top face; wherein the vertical longtudinal limb and the horizontal longitudinal limb are integrated to form a substantially L-shaped cross-section, wherein the longitudinal horizontal limb and the longitudinal vertical limb have sufficient thickness to demonstrate insulating properties.
Claim 4
Dependent Claim
106 words
An elongate cavity sealing profile comprised of a flexible compressible synthetic foam of polyethylene, polypropylene, polyurethane, ethylene, vinyl acetate, polyvinyl chloride, or polystyrene having thermal insulating properties wherein the sealing profile is characterized by having a longitudinal horizontal limb having an outer longitudinal face, an inner longitudinal surface, and a longitudinal edge; and a longitudinal vertical limb having an outer longitudinal face, an inner longitudinal face, and a longitudinal top face; wherein the vertical longtudinal limb and the horizontal longitudinal limb are integrated to form a substantially L-shaped cross-section, wherein the longitudinal horizontal limb and the longitudinal vertical limb have sufficient thickness to demonstrate insulating properties.
Claim 5
Dependent Claim
32 words
An elongate cavity sealing profile as claimed in claim 2 characterized in that the top face of said profile extends obliquely downwards from its inner longitudinal face to its outer longitudinal face.
Claim 6
Dependent Claim
52 words
An elongate cavity sealing profile according to claims 2 or 3 characterized in that said profile is provided with a moisture-proof, tear resistant, flexible film, which is fastened to the top face of the vertical limb of said profile, said film extending in both directions beyond the top face of said profile.
Claim 7
Dependent Claim
34 words
An elongate cavity sealing profile in accordance with claims 2, 3 or 4, characterized in that the top surface of the horizontal limb of said profile is in the form of a tongue-and-groove joint.
Claim 8
Dependent Claim
34 words
An elongate cavity sealing profile in accordance with claims 2, 3 or 4, characterized in that the top surface of the horizontal limb of said profile is in the form of a ship-lap joint.
Claim 9
Dependent Claim
83 words
A method of construction thermally insulating cavity walls comprising A) inserting at the base of the cavity sealing profile of claim 2; B) inserting the edge of a thermal insulating board in the L-shaped portion of said profile; C) progressively constructing the inner and outer cavity walls while adding additional insulating boards until the desired height is obtained; and D) capping the upper edge of said insulating board with a second elongate sealing profile which is placed in opposition to the base profile.
Claim 10
Dependent Claim
28 words
A process according to claim 7 characterized in that the top face of said profile extends obliquely downwards from its inner longitudinal face to its outer longitudinal face.
Claim 11
Dependent Claim
48 words
A process according to claim 7 characterized in that said elongate sealing profile further comprises a moisture-proof, tear resistant, flexible film, which is fastened to the top face of the vertical limb of said profile, said film extending in both directions beyond the top face of said profile.
