A stapling flange and a flashing flange extend widthwise from the top and bottom cover strips respectively along a first side of the insulation strip and are sealed to each other along a bond line near the first side. An interior flange extends widthwise from the top cover strip, along the other side of the insulation strip. The flanges are usable to seal the thermal insulation pad against the weather and air barrier on the outside of a building wall and against the vapour barrier on the inside of a building wall. The flanges extending from the top cover strip are usable to stretch the top cover strip over the insulation strip to form a cushioned liner around a wall opening. ## Claims ### Claim 1 A thermal insulation pad for insulating a gap space between a window or door frame and a wall opening, said thermal insulation pad comprising: a compressible insulation strip having a rectangular cross-section, a length, a width, a top surface and a bottom surface, a first and second opposite sides defining said width, and a thickness; a top cover strip covering said top surface; a bottom cover strip covering said bottom surface; a stapling flange extending widthwise from said bottom cover strip, from said first side, and a flashing flange extending widthwise from said top cover strip, from said first side, and extending in a spaced-apart relationship with and over said stapling flange; said stapling flange and said flashing flange being bonded to each other along a bond line adjacent said compressible insulation strip; said stapling flange and said flashing flange extending away from said bond line; said bond line constituting a seal to prevent an infiltration of moisture into said insulation strip. ### Claim 2 (depends on 1) The thermal insulation pad as claimed in claim 1, further comprising an interior flange extending widthwise from said top cover strip, from said second side. ### Claim 3 (depends on 2) The thermal insulation pad as claimed in claim 2, wherein said top cover strip, said flashing flange and said interior flange extend lengthwise beyond said length and jointly define an end flap. ### Claim 4 (depends on 1) The thermal insulation pad as claimed in claim 1, wherein said top and bottom cover strips are made of strong weather-resistant paper. ### Claim 5 (depends on 2) The thermal insulation pad as claimed in claim 2, wherein said top cover strip, said flashing flange and said interior flange have transverse lines printed thereon. ### Claim 6 (depends on 1) The thermal insulation pad as claimed in claim 1 wherein said stapling flange has a strip of adhesive thereon. ### Claim 7 (depends on 2) The thermal insulation pad as claimed in claim 2, wherein said interior flange has a strip of adhesive thereon. ### Claim 8 (depends on 1) The thermal insulation pad as claimed in claim 1, wherein said flashing flange has a bead of caulking and a peeled-off protective paper strip thereon. ### Claim 9 (depends on 1) The thermal insulation pad as claimed in claim 1, wherein said bond line has a width of about ½ inch. ### Claim 10 (depends on 1) The thermal insulation pad as claimed in claim 1, wherein said insulation strip is made of fibreglass insulation. ### Claim 11 (depends on 1) The thermal insulation pad as claimed in claim 1, wherein said width is about 5-/2 to 6 inches, and said thickness is about ¾ of an inch. ### Claim 12 (depends on 1) The thermal insulation pad as claimed in claim 1, wherein said stapling flange and said flashing flange extend from said bottom cover strip and said top cover strip respectively, a distance of about 1½ to 2 inches. ### Claim 13 (depends on 2) The thermal insulation pad as claimed in claim 2, wherein said interior flange extends from said top cover strip over a distance of about 1½ to 2 inches. ### Claim 14 (depends on 1) The thermal insulation pad as claimed in claim 1, further comprising a transverse notch in said top cover strip and said insulation strip for defining a shim pocket in said gap space. ### Claim 15 A thermal insulation pad for insulating a gap space between a window or door frame and a wall opening, said thermal insulation pad comprising: a compressible insulation strip having a rectangular cross-section, a length, a width, a top surface and a bottom surface, a first and second opposite sides defining said width, and a thickness; a flexible top cover strip covering said top surface; a flexible bottom cover strip covering said bottom surface; a stapling flange extending widthwise from said bottom cover strip, from said first side, continuously along said length; a flashing flange extending widthwise from said top cover strip, from said first side, continuously along said length, and a plurality of spaced-apart empty spaces in said insulation strip and said top cover strip wherein each of said empty spaces is defined between said first and second sides. ### Claim 16 (depends on 15) The thermal insulation pad as claimed in claim 15, further having patches removably covering at least some of said empty spaces. ### Claim 17 In combination, a wall having a wall thickness, an outdoor surface, an indoor surface and a wall opening therein, and a thermal insulation pad circling said wall opening, said thermal insulation pad comprising: a compressible insulation strip having an insulation thickness, a rectangular cross-section, a width substantially similar to said wall thickness a top surface and a bottom surface, and a first and second opposite sides defining said width said width extending perpendicular to a plane of said wall opening; a flexible top cover strip covering said top surface; a flexible bottom cover strip covering said bottom surface; said flexible top cover strip having a flashing flange extending widthwise therefrom, from said first side, and an interior flange extending widthwise therefrom, from said second side; said flashing flange being affixed to said outdoor surface and said interior flange being affixed to said indoor surface and said flexible top cover being stretched over said compressible insulation strip, and defining a perimeter of said wail opening. ### Claim 18 (depends on 17) The combination as claimed in claim 17, wherein said wall further comprises a weather and air barrier on said outdoor surface and said thermal insulation pad further has a stapling flange extending widthwise from said bottom cover strip, from said first side, and said weather and air barrier being partly enclosed between said stapling flange and said flashing flange. ### Claim 19 (depends on 18) The combination as claimed in claim 18, wherein said wall further comprises a vapour barrier on said indoor surface, and said interior flange partly overlaps said vapour barrier. ### Claim 20 (depends on 18) The combination as claimed in claim 18, wherein said flashing flange and said stapling flange being sealed to each other along a bond line extending along said first side of said compressible insulation strip.
