8. The window unit of claim 1 further comprising at least one filler arranged between the outer elongate strip and the inner elongate strips, the filler including a desiccant.

9. The window unit of claim 1 further comprising an elongate gasket disposed between the first inner elongate strip and the second inner elongate strip, wherein the elongate gasket further defines the intermediate pane gap.

10. A window unit comprising:

a first pane, a second pane, and an intermediate pane disposed between the first pane and the second pane;

a spacer comprising:

an outer elongate strip (i) extending between inner surfaces of the first and second panes, (ii) having a first surface, and (iii) having a second surface contacting and supporting the intermediate pane;

first and second inner elongate strips, each having a first surface and a second surface, the inner elongate strips arranged so that each of the first surfaces of the inner elongate strips are spaced from the second surface of the outer elongate strip towards an interior of the window unit, the inner elongate strips being spaced from each other to form an elongate intermediate pane gap;

a first outer support leg extending between the outer elongate strip and the first inner elongate strip;

a second outer support leg extending between the outer elongate strip and the second inner elongate strip;

a first inner support leg extending between the outer elongate strip and the first inner elongate strip, the first inner support leg positioned between the two outer support legs; and

a second inner support leg extending between the outer elongate strip and the second inner elongate strip, the second inner support leg positioned between the two outer support legs,

wherein the spacer defines a first sealant cavity comprising sealant between the first pane and the first outer support leg and a second sealant cavity comprising sealant between the second pane and the second outer support leg,

wherein the outer elongate strip and the first inner elongate strip each extend a first distance from the first outer support leg to the inner surface of the first pane, and wherein the outer elongate strip and the second inner elongate strip each extend a second distance from the second outer support leg to the inner surface of the second pane.

11. A window unit comprising:

a first pane, a second pane, and an intermediate pane disposed between the first pane and the second pane;

a spacer comprising:

an outer elongate strip extending from an inner surface of the first pane to an inner surface of the second pane and contacting and supporting the intermediate pane;

first inner elongate strip extending from the first pane to the intermediate pane;

a second inner elongate strip extending from the intermediate pane to the second pane;

a first support leg extending between the outer elongate strip and the first inner elongate strip; and

a second support leg extending between the outer elongate strip and the second inner elongate strip,

wherein the outer elongate strip and the first inner elongate strip each extend a first distance from the first support leg to the inner surface of the first pane, and wherein the outer elongate strip and the second inner elongate strip each extend a second distance from second support leg to the inner surface of the second pane.

12. The window unit of claim 11 , further comprising an elongate gasket disposed between the first inner elongate strip and the second inner elongate strip, wherein the elongate gasket frictionally receives the intermediate pane.

13. The window unit of claim 11 , further comprising:

a third support leg extending between the outer elongate strip and the first inner elongate strip and arranged between the first support leg and the intermediate pane; and

a fourth support leg extending between the outer elongate strip and the second inner elongate strip and arranged between the second support leg and the intermediate pane.

14. The window unit of claim 11 , wherein the outer elongate strip, the first inner elongate strip, and the second inner elongate strip have an undulating shape.

15. The window unit of claim 13 , wherein:

the first support leg, the outer elongate strip and the first inner elongate strip define a first sealant cavity having a sealant disposed therein, wherein the sealant sealably contacts the first pane; and

the second support leg, the outer elongate strip and the second inner elongate strip define a second sealant cavity having the sealant disposed therein, wherein the sealant sealably contacts the second pane.

16. The window unit of claim 2 , wherein the first and second inner support legs are arranged at the non-perpendicular angle with respect to the outer elongate strip such that first ends of the first and second inner support legs proximate the outer elongate strip are closer to the intermediate pane than second ends of the first and second inner support legs proximate the first and second inner elongate strips, respectively.

17. The window unit of claim 16 , wherein the non-perpendicular angle of the first and second inner support legs with respect to the outer elongate strip provides for easier alignment of the intermediate pane within the elongate intermediate pane gap of the spacer.

18. The window unit of claim 15 , wherein the third and fourth support legs, the first and second inner elongate strips, and the outer elongate strip define an intermediate sealant cavity having a sealant disposed therein, wherein the sealant sealably contacts the intermediate pane.
