Horizontal insulating structures can be vertically spaced apart from one another along the vertical pillar structure to define first vertical gaps therebetween at first locations away from the outer wall and to define second vertical gaps therebetween at the outer wall, where the second vertical gaps are wider than the first vertical gaps.
