an outer member surrounding the plurality of ribs and joined to the plurality of ribs at an outer lateral end of the plurality of ribs; and

a central member extending along a vertical lateral axis through the center of the frame insert within the outer member and joined to the outer member.

2. The frame insert of claim 1 , wherein the plurality of voids comprise a plurality of slots.

3. The frame insert of claim 1 , wherein the plurality of voids are laterally staggered across the plurality of ribs.

4. The frame insert of claim 1 , wherein each of the plurality of voids are formed in a longitudinal face of the single corresponding rib.

5. The frame insert of claim 1 , wherein the plurality of voids are near or adjacent to upward most lateral ends of the plurality of ribs.

6. The frame insert of claim 1 , wherein a majority of the plurality of ribs extend from the central member to the outer member.

7. The frame insert of claim 6 , wherein the outer member laterally surrounds the plurality of ribs and is joined to the plurality of ribs at the outer lateral end of the ribs, and wherein the central member extends from a first position of the outer member to a second position of the outer member and the central member is joined to a majority of the plurality of ribs at an inner lateral end of the ribs.

8. The frame insert of claim 7 , wherein joints between the plurality of ribs and the outer member and joints between the plurality of ribs and the central member are rounded, such that the plurality of chambers defined by the plurality of ribs, the outer member, and the central member have rounded corners.

9. The frame insert of claim 7 , wherein a majority of the plurality of chambers defined by the plurality of ribs, the outer member, and the central member have a cross-sectional shape that is substantially parallelogrammatic or trapezoidal.
