The insert is configured to fit within the spacer of the glazing unit. A typical glazing unit has at least two outer glazing sheets separated by a substantially rigid, U-shaped spacer disposed about the perimeter of the sheets to create an interior cavity between the outer sheets and the spacer. The width and height of the body of the insert are adapted to allow the insert to fit within the U-shaped spacer. The spacer has a longitudinal length dimension substantially equal to the perimeter of the glazing sheets. The body of the insert also has a longitudinal length dimension substantially equal to the length of the spacer. The body of the insert is fabricated from a non-flowable material having substantially stable dimensions. In one embodiment of the invention, the insert includes an inwardly facing, intermediate glazing sheet-receiving channel that is adapted to slidably receive and position an intermediate glazing sheet. ## Claims ### Claim 1 An insert for a glazing unit having at least two outer glazing sheets separated by a substantially rigid, U-shaped spacer disposed about the perimeter of the sheets to create an interior cavity between the outer sheets and the spacer; the spacer having an interior width and an interior height defining upper and lower corners and a lower wall; the insert comprising: a body having a width, a height, and a longitudinal length; said width and height of said body adapted to fit within the U-shaped spacer; the width and height of the body being adapted to cause the body to be positioned adjacent at least one upper corner and adjacent the lower wall; and said body being fabricated from a non-flowable material having substantially stable dimensions. ### Claim 2 (depends on 1) The insert of claim 1, wherein said body defines at least one intermediate glazing sheet-receiving channel; the sheet-receiving channel being longitudinally disposed and adapted to face the interior cavity; the sheet-receiving channel adapted to receive an intermediate glazing sheet. ### Claim 3 (depends on 2) The insert of claim 2, wherein the sheet-receiving channel has a depth and a width, said width of said sheet-receiving channel being adapted to be larger than the thickness of the intermediate glazing sheet in the channel. ### Claim 4 (depends on 1) The insert of claim 1, wherein the body defines an intermediate glazing sheet-receiving channel; the intermediate glazing sheet-receiving channel being adapted to receive an edge of an intermediate glazing sheet; the intermediate glazing sheet-receiving channel being at least partially defined by a pair of angled sidewalls. ### Claim 5 (depends on 4) The insert of claim 4, wherein the angled sidewalls are disposed on opposite sides of the channel. ### Claim 6 (depends on 5) The insert of claim 5, wherein the intermediate glazing sheet-receiving channel is centrally disposed in the body. ### Claim 7 (depends on 5) The insert of claim 5, wherein the intermediate glazing sheet-receiving channel is non-centrally disposed in the body. ### Claim 8 (depends on 1) The insert of claim 1, wherein the body defines at least one longitudinal void. ### Claim 9 (depends on 1) The insert of claim 1, wherein the body includes at least one retaining member; the retaining member being adapted to engage the U-shaped spacer. ### Claim 10 (depends on 9) The insert of claim 9, wherein the body includes a cover member that cooperates with each retaining member. ### Claim 11 (depends on 1) The insert of claim 1, wherein the body defines at least one inwardly-facing thermal channel disposed longitudinally in the body. ### Claim 12 (depends on 11) The insert of claim 11, wherein the thermal channel is V-shaped. ### Claim 13 (depends on 11) The insert of claim 11, wherein the body defines a second thermal channel disposed longitudinally in the body. ### Claim 14 (depends on 1) The insert of claim 1, wherein the body has a cross-section that is substantially V-shaped. ### Claim 15 (depends on 1) The insert of claim 1, wherein the body substantially fills the U-shaped spacer. ### Claim 16 (depends on 1) The insert of claim 1, wherein the body has a width and height adapted to cause the body to extend from one of the upper corners to one of the lower corners of the spacer. ### Claim 17 (depends on 16) The insert of claim 16, wherein the body is curved. ### Claim 18 An insert for a glazing unit having at least two outer glazing sheets separated by a substantially rigid, U-shaped spacer disposed about the perimeter of the sheets to create an interior cavity between the outer sheets and the spacer; the spacer having an interior width and an interior height; the insert comprising: a body having a width and a height; said body being adapted to fit within the U-spacer; and said body defining at least one longitudinal void. ### Claim 19 (depends on 18) The insert of claim 18, wherein the body is fabricated from a non-flowable material having substantially stable dimensions. ### Claim 20 (depends on 18) The insert of claim 18, wherein the body is fabricated from a cured foam. ### Claim 21 (depends on 18) The insert of claim 18, wherein the body defines an intermediate glazing sheet-receiving channel; said sheet-receiving channel being longitudinal and disposed to face the interior cavity; said sheet-receiving channel being adapted to receive the edge of an intermediate glazing sheet. ### Claim 22 (depends on 21) The insert of claim 21, wherein the sheet-receiving channel is defined by a pair of angled sidewalls. ### Claim 23 An insert for a glazing unit having at least two outer glazing sheets separated by a substantially rigid, U-shaped spacer disposed about the perimeter of the sheets to create an interior cavity between the outer sheets and the spacer; the U-shaped spacer having an interior width and an interior height; the insert comprising: a body having a width and a height; the body being adapted to fit within the U-shaped spacer; and the body having a cross-section that is substantially V-shaped. ### Claim 24 (depends on 23) The insert of claim 23, wherein the height of the body is adapted to be substantially equal to the interior height of the U-shaped spacer. ### Claim 25 (depends on 23) The insert of claim 23, wherein the body includes at least one retaining member; the retaining member being adapted to engage the U-shaped spacer. ### Claim 26 (depends on 25) The insert of claim 25, wherein the body includes a cover member cooperating with each retaining member. ### Claim 27 (depends on 23) The insert of claim 23, wherein the body is fabricated from a non-flowable material having substantially stable dimensions. ### Claim 28 (depends on 27) The insert of claim 27, wherein the body is fabricated from a cured foam.
