A lightweight multilayer heat reflective concrete cure blanket having a moisture-impervious top outer layer, a moisture-impervious bottom outer layer, and the top and bottom layers sealingly connected to each other at the boundaries of the layers to form a moisture-impervious chamber between the first and second layers. The chamber includes at least one bubble type insulative layer therein, and the bottom surface of the blanket comprises a heat reflective material to reflect heat emanating from the concrete when the blanket is placed over the concrete. In a further embodiment, heat reflective material is applied to at least one inner bubble type layer to reflect additional heat which radiates from the concrete through the insulative layer and back towards the concrete.

What is claimed is: 1. A lightweight multilayer heat reflective concrete cure blanket, comprising: a first flexible structure having a first outer peripheral edge and comprising a first moisture-impervious outer film and a first flexible undulating film heat sealed to the first moisture-impervious outer film forming a plurality of first air-filled insulative pockets and a plurality of first open spaces between the first air-filled pockets; a second flexible structure having a second outer peripheral edge and comprising a second moisture-impervious outer film and a second flexible undulating film heat sealed to the second moisture-impervious outer film forming a plurality of second air-filled insulative pockets and a plurality of second open spaces between the second air-filled insulative pockets, wherein the second moisture-impervious outer film includes a reflective material applied to the second moisture-impervious outer film; and the first flexible structure sealed to the second flexible structure about the first and second outer peripheral edges including a chamber space formed between the first air-filled insulative pockets and the second air-filled insulative pockets, wherein the first and second open spaces face the second and first air-filled pockets, respectively, and communicate in a heat transfer path as to form a flexible heat reflective concrete cure blanket. 2. The heat reflective concrete cure blanket of claim 1, wherein the second undulating film includes a reflective material applied to the second undulating film. 3. The heat reflective concrete cure blanket of claim 1, wherein the first moisture-impervious outer film includes a reflective material applied to the first moisture-impervious outer film. 4. The heat reflective concrete cure blanket of claim 1, wherein the first moisture-impervious outer film is substantially dark in color to absorb ambient heat into the concrete cure blanket. 5. The heat reflective concrete cure blanket of claim 1, wherein the second outer film includes a nonstick smooth surface. 6. A lightweight multilayer heat reflective concrete cure blanket, comprising: a first flexible structure comprising a first unslitted moisture-impervious outer film and a first flexible undulating film heat sealed to the first unslitted moisture-impervious outer film forming a first bubble-type insulative layer; a second flexible structure comprising a second unslitted moisture-impervious outer film and a second flexible undulating film heat sealed to the second unslitted moisture-impervious outer film forming a second bubble-type insulative layer, wherein the second unslitted moisture-impervious outer film includes a reflective material applied to the second unslitted moisture-impervious outer film as to reflect heat away from the second flexible structure; the first bubble-type layer comprising a plurality of first insulative pockets and a plurality of first open spaces between the first insulative pockets, and the second bubble-type layer comprising a plurality of second insulative pockets and a plurality of second open spaces between the second insulative pockets, wherein the first and second insulative pockets alternately face the second and first open spaces, respectively, forming a chamber space between the first and second insulative pockets; and the first flexible structure heat sealed to the second flexible structure, wherein the second open spaces between the second insulative pockets communicate with the first insulative pockets in a heat transfer path as to form a flexible heat reflective concrete cure blanket. 7. The lightweight multilayer heat reflective concrete cure blanket of claim 6, wherein the second bubble-type insulative layer comprises a reflective material applied to the second bubble-type insulative layer. 8. The lightweight multilayer heat reflective concrete cure blanket of claim 6, wherein the second unslitted moisture-impervious outer film is not covered by any material. 9. The lightweight multilayer heat reflective concrete cure blanket of claim 6 further comprising a third flexible structure comprising a third unslitted moisture-impervious film and a second flexible undulating film heat sealed to the third unslitted moisture-impervious film forming a third bubble-type insulative layer, wherein the unslitted moisture-impervious film includes a reflective material applied to the third unslitted moisture-impervious film; and, the third flexible structure heat sealed in between the first flexible structure and the second flexible structure. 10. A lightweight multilayer heat reflective concrete cure blanket, comprising: a first flexible structure having a first outer peripheral edge and comprising a first moisture-impervious outer film and a first flexible undulating film heat sealed to the first moisture-impervious outer film forming a plurality of first air-filled insulative pockets and a plurality of first open spaces between the first air-filled pockets; a second flexible structure having a second outer peripheral edge and comprising a second moisture-impervious outer film and a second flexible undulating film heat sealed to the second moisture-impervious outer film forming a plurality of second air-filled insulative pockets and a plurality of second open spaces between the second air-filled insulative pockets, wherein the second undulating film includes a reflective material applied to the second undulating film; and the first flexible structure sealed to the second flexible structure about the first and second outer peripheral edges including a chamber space formed between the first air-filled insulative pockets and the second air-filled insulative pockets, wherein the first and second open spaces face the second and first air-filled pockets, respectively, and communicate in a heat transfer path as to form a flexible heat reflective concrete cure blanket. 11. The heat reflective concrete cure blanket of claim 10, wherein the second moisture-impervious outer film includes a reflective material applied to the second moisture-impervious outer film. 12. The heat reflective concrete cure blanket of claim 10, wherein the first moisture-impervious outer film includes a reflective material applied to the first moisture-impervious outer film. 13. The heat reflective concrete cure blanket of claim 10, wherein the first moisture-impervious outer film is substantially dark in color to absorb ambient heat into the concrete cure blanket. 14. The heat reflective concrete cure blanket of claim 10, wherein the second outer film includes a nonstick smooth surface.
