The invention claimed is: 1. 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 f
The invention claimed is: 1. 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 description="In-line Formulae" end="lead"n=[h/d-1]횞[c/d-1]description="In-line Formulae" end="tail" and d is description="In-line Formulae" end="lead"d=f횞[6-h=(1/h)]횞√{square root over (e/4)}description="In-line Formulae" end="tail" 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. 2. The glazing of claim 1, wherein the substance comprises a polymeric solution. 3. The glazing of claim 1, wherein the spacers are fastened to the first glass sheet or the second glass sheet by adhesive bonding. 4. The glazing of claim 3, wherein the spacers are fastened with an adhesive or an enamel. 5. The glazing of claim 1, wherein the spacers are steel balls. 6. The glazing of claim 1, wherein the spacers are made of glass. 7. The glazing of claim 1, wherein the spacers have the shape of a ball or a cylinder. 8. The glazing of claim 1, wherein the spacers have the shape of a cruciform. 9. The glazing of claim 1, wherein h ranges from 0 to 4 m. 10. The glazing of claim 1, wherein f ranges from 1.3 to 2.3. 11. The glazing of claim 1, wherein the spacers are distributed on the first surface or the second surface in the shape of a first trapezoidal geometry and a second trapezoidal geometry, wherein the first trapezoidal geometry and the second trapezoidal geometry are distributed symmetrical with respect to a midline of the glazing, the first trapezoidal geometry is above the midline of the glazing and the widest part of the first trapezoidal geometry is closest to the upper edge, and the second trapezoidal geometry is below the midline of the glazing and the widest part of the second trapezoidal geometry is closest to the lower edge. 12. The glazing of claim 1, further comprising a seal around the upper edge, first side edge, lower edge, and second side edge, wherein the seal comprises a butyl rubber seal between the first face and the second face, a rigid acrylic bead, and a silicon seal. 13. The glazing of claim 1, wherein the glazing is a thermochromic glazing. 14. The glazing of claim 13, further comprising at least one laminated glass pane or at least one insulating glass pane. 15. 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 an inhomogenous distribution, wherein description="In-line Formulae" end="lead"n=c/d-1description="In-line Formulae" end="tail" wherein d is description="In-line Formulae" end="lead"d=f횞[6-g+(1/g)]횞√{square root over (e/4)}description="In-line Formulae" end="tail" wherein d is the distance between two spacers along a row parallel to a lower edge of the glazing at a height g above a bottom edge of the glazing, e is the thickness of the thinnest glass sheet, and f is the safety factor. 16. The glazing of claim 15, wherein h ranges from 0 to 4 m. 17. The glazing of claim 15, wherein f ranges from 1.3 to 2.3. 18. The glazing of claim 15, wherein the substance comprises a polymeric solution. 19. The glazing of claim 15, wherein the spacers are fastened to the first glass sheet or the second glass sheet by adhesive bonding. 20. The glazing of claim 19, wherein the spacers are fastened with an adhesive or an enamel. 21. The glazing of claim 15, wherein the spacers are steel balls. 22. The glazing of claim 15, wherein the spacers are made of glass. 23. The glazing of claim 15, wherein the spacers have the shape of a ball or a cylinder. 24. The glazing of claim 15, wherein the spacers have the shape of a cruciform. 25. The glazing of claim 15, wherein the glazing is a thermochromic glazing. 26. The glazing of claim 25, further comprising at least one laminated glass pane or at least one insulating glass pane.
