Abstract:
1. A fenestration apparatus comprising: first and second glazing panes capable of being installed in an opening of a building envelope; a tessellated structure disposed between the first and second glazing panes, the tessellated structure comprising: at least one partition having a first face and a second face, the at least one partition defining a plurality of spatially separated cells within a substantially contiguous region of the opening, each of the plurality of spatially separated cells having a cell width, a cell area, and a cell depth, wherein the at least one partition has a thickness that is less than or equal to 0.01 inches; wherein the at least one partition comprises reflective film; wherein the tessellated structure comprises a honeycomb structure; wherein each of the plurality of spatially separated cells is at least partially surrounded by at least one face of the at least one partition, wherein the luminous reflectance of the first face of the at least one partition is greater than or equal to about 95% when measured with respect to CIE illuminant D wherein the fenestration apparatus has a visible light transfer efficiency greater than or equal to 85% when measured with respect to light entering the fenestration apparatus at an incident angle of 75°, and wherein a U-factor of the fenestration apparatus is reduced by at least 25% when compared to a fenestration device having a same configuration but no tessellated structure.
