Abstract
An insulated glazing unit including a first glass element and a second glass element having congruent shapes. The insulated glazing unit also includes a plurality of elongated spacers disposed between the first glass element and the second glass element to space the first glass element from the second glass element. The spacers are in rolling, line contact with a surface of one or both of the first glass element and the second glass element, and each spacer is elongated along an axis. The spacers are oriented on the surface such that the axis of each of the spacers is tangent to one or more imaginary circular lines superimposed on the surface and having a common center.
