1. A skylight assembly for use on a building to allow transmission of light from a building exterior to a building interior while limiting heat transfer, the skylight assembly comprising: a translucent glazing unit including a top plastic layer having a surface facing the building exterior and a bottom plastic layer having a surface facing the building interior spaced apart from the top plastic layer, the top and bottom plastic layers having a sealed outer periphery defining an enclosed cavity, at least a portion of the enclosed cavity being filled with insulating aerogel particles which allow light transmission and limit heat transfer and wherein a plurality of alternating depressions are disposed in the top and bottom plastic layers to retain said aerogel particles in a substantially uniform thickness; anda peripheral frame having polymeric material formed in-situ entrapping and directly bonding to a peripheral region of the translucent glazing unit, the polymeric material contacting the sealed outer periphery, the frame overlying the top plastic layer being a first thickness, and the frame being in direct contact with the bottom plastic layer being a second thickness and forming a leak-tight joint between the periphery region of the translucent glazing unit and the frame while leaving a center region of the translucent glazing unit free to transmit light. 2. The skylight assembly of claim 1, further defining a plurality of inner web members disposed between the top and bottom plastic layers of the glazing unit defining a plurality of internal channels within the enclosed cavity. 3. The skylight assembly of claim 2, wherein the internal channels are elongated and substantially parallel. 4. The skylight assembly of claim 3, wherein the sealed outer periphery of the glazing unit is defined at least in part by a capping material sealing closed opposed ends of the internal channels to trap aerogel therein while prevent intrusion of polymeric material during in-situ forming of the peripheral frame. 5. The skylight assembly of claim 2, wherein the glazing unit further comprises a second plurality of web members disposed between the top and bottom plastic layers defining a grid within the enclosed cavity to limit movement of the aerogel particles. 6. The skylight assembly of claim 1, further comprising a light transmitting domed polymeric panel mounted to an outer peripheral region of the top plastic layer of the translucent glazing unit defining an enclosed space therebetween. 7. The skylight assembly of claim 1 wherein the polymeric material comprises a condensation-polymerization-reaction-derived heteronuclear polymer having, before combination, a first precursor and a second precursor adapted to combine in a condensation polymerization reaction. 8. The skylight assembly of claim 7, wherein the condensation-polymerization-reaction-derived heteronuclear polymer comprises a RIM-injected polyurethane. 9. The skylight assembly of claim 1, wherein the frame includes a curb and a flashing capable of being mounted on a pitched roof, the translucent glazing unit having at least one channel within the enclosed cavity, the channel having a longitudinal axis transversely to the roofs pitch. 10. The skylight assembly of claim 1, wherein the top plastic layer of the glazing unit is thicker than the bottom plastic layer. 11. The skylight assembly of claim 1, wherein the first thickness is different from the second thickness. 12. The skylight assembly of claim 1, wherein the glazing unit has visible light transmission through the glazing unit ranging from 10% to 75% of initial visible light impinging on the top plastic layer. 13. A skylight assembly for use on a building to transmit light from a building exterior to a building interior while limiting heat transfer, the skylight assembly comprising: a translucent glazing unit including a center region, a top layer having a top layer surface facing the building exterior and a bottom layer having a bottom layer surface facing the building interior spaced apart from the top layer surface, the top and bottom layers having a sealed outer periphery defining an enclosed cavity, at least a portion of the cavity being filled with insulating aerogel which allow light transmission and limit heat transfer and wherein a plurality of alternating depressions are disposed in the top and bottom layers to retain said aerogel in a substantially uniform thickness;a light transmitting polymeric domed panel having a domed panel surface facing the building exterior mounted to an outer peripheral region of the top layer of the translucent glazing unit defining an enclosed space therebetween; anda peripheral frame formed in-situ from a polymeric material, the frame entrapping the translucent glazing unit including the bottom layer surface and at least one of the top layer surface and the domed panel surface, the frame being adapted to attach directly to the domed panel forming a leak-tight joint frame while leaving the center region of the translucent glazing unit free to transmit light. 14. The skylight assembly of claim 13 wherein the skylight assembly has a ratio of solar heat gain coefficient to fractional light transmittance ranging from 0.95 to 1.5. 15. The skylight assembly of claim 14, wherein the ratio is capable of variation when a plurality of depressions or protrusions are in the top layer of the translucent glazing unit. 16. The skylight assembly of claim 13, wherein the skylight assembly has a U-value from 0.25 to 1.5 W/(m2*° K) when using a 1 inch thick section of aerogel in the cavity. 17. The skylight assembly of claim 13, wherein the sealed outer periphery of the glazing unit resists intrusion into a cavity of moldable polymeric material during in-situ forming of the frame. 18. The skylight assembly of claim 13, wherein the skylight assembly hingedly connects to a curb, the skylight assembly being capable of opening from the curb when providing ventilation. 19. A skylight assembly for use on a building to allow transmission of light from a building exterior to a building interior while limiting heat transfer, the skylight assembly comprising: a translucent glazing unit including a center region, a plastic top layer having a top surface facing the building exterior, and a plastic bottom layer having a surface facing the building interior spaced apart from the plastic top layer, and end caps, the top and bottom layers having a sealed outer periphery defining an enclosed cavity, at least a portion of the cavity being filled with insulating aerogel particles which allow light transmission and limit heat transfer and wherein a plurality of alternating depressions are disposed in the plastic top and plastic bottom layers to retain said aerogel particles in a substantially uniform thickness; anda peripheral frame having a polymeric material formed in-situ entrapping a peripheral region of the translucent glazing unit including at least the bottom layer surface forming a leak-tight joint directly between the periphery region of the translucent glazing unit and the frame while leaving the center region of the translucent glazing unit free to transmit light, wherein the peripheral frame includes a curb contacting the building exterior, the polymeric material of the frame exerting a force on the end cap exceeding 1 lbf/in2 relative to atmospheric pressure.
