Abstract
Methods of making an insulated glass unit (IGU) are provided with a thin center pane in a triple IGU (regardless of CTE or glass type/composition), including various embodiments for reducing, preventing, and/or eliminating edge warp when a heated adhesive is utilized as the spacer material in the IGU.

-68. (canceled)
An insulating glass unit, comprising:
- a. a first pane of glass, having a first side and a second side, a first thickness of at least 2.5 mm, and a CTE 1;
- b. a second pane of glass, having a first side and a second side, a second thickness of at least 2.5 mm, and a CTE 2;
- and
- c. a third pane of glass, having a first side and a second side, having a third thickness of not greater than 2.5 mm, and a CTE3,
- d. a first thermoplastic spacer, positioned between the second side of the first pane and the first side of the third pane to define a first gas cavity having a first cavity depth;
- and
- e. a second thermoplastic spacer, positioned between the second side of the third pane and the first side of the second pane to define a second gas cavity having a second cavity depth,
- wherein the IGU has no visual distortion of observable edge warp on the third pane.
