Patent ID: 7306833

Claim:
A glazing comprising: (i) a first glass sheet having a first surface and a second glass sheet having a second surface, wherein the first surface and the second surface face each other; (ii) spacers between the first glass sheet and a second glass sheet to separate the first surface of the first glass sheet and the second surface of the second glass sheet by a distance to provide a space wherein the space contains substantially no gas; and (iii) a liquid or solid containing substance containing substantially no gases at least partially filling the space; wherein the spacers are fastened to at least one of the first glass sheet or the second glass sheet; wherein the glazing has an upper edge, a lower edge, a first side edge, a second side edge, a width c, a height h, and a midline parallel to the lower edge and midway between the upper edge and the lower edge, wherein the spacers are non-randomly distributed on the first surface or the second surface without forming a peripheral rectangular shape, and wherein n spacers are distributed on the first surface or the second surface in a parallelepipedal shape in a homogenous distribution, wherein n=[h/d− 1 ]×[c/d −1] and d is d=f ×[6 −h= (1 /h )]×√{square root over ( e /4)} wherein d is the distance between two spacers along a row parallel to a lower edge of the glazing, e is the thickness of the thinnest glass sheet, h is the height of the glazing, and f is the safety factor.
