Section: claims

1. Radiant barrier apparatus for reflecting long wave radiation, comprising, in combination: base means, including a flexible chip having a first substantially clear film substrate having a first side and a second side; and  metallized layer means including first and second layer secured to one of each of the first and second sides of the substrate for reflecting long wave infra red radiation. 2. The apparatus of claim 1 in which the chip is crinkled and the metallized layer means comprises a first metallized layer on the first side and a second metallized layer on the second side. 3. The apparatus of claim 1 in which the chip is fan folded, and the metallized layer means comprises a first metallized layer on the first side and a second metallized layer on the second side. 4. The apparatus of claim 1 in which the chip includes a second substantially clear film substrate, and each substantially clear film substrate has a first side and a second side. 5. The apparatus of claim 4 in which the first and second substantially clear film substrates include outer peripheries, and they are sealed together at their outer peripheries to defined bag means. 6. The apparatus of claim 5 in which the bag means is filled with a gas. 7. The apparatus of claim 6 in which the metallized layer means includes the first layer secured to the first side of the first film substrate and the second layer secured to the first side of the second film substrate. 8. The apparatus of claim 7 in which metallized layer means further includes a third layer secured to the second side of the first film substrate and a fourth layer secured to the second side of the second film substrate. 9. The apparatus of claim 6 in which the bag means comprises a plurality of gas filled bags. 10. The apparatus of claim 9 in which the plurality of gas filled bags are secured together at their outer peripheries to comprise a sheet of gas filled bags. 11. The apparatus of claim 4 in which the first and second clear film substrates are secured together at a plurality of horizontal connecting lines and a plurality of vertical connecting lines to define a plurality of bags in a sheet configuration. 12. The apparatus of claim 9 in which each bag is filled with a gas. 13. The apparatus of claim 4 in which the metallized layer means is disposed between the first and second substantially clear film substrate. 14. The apparatus of claim 13 in which the first substantially clear film substrate has a first thickness, and the second substantially clear film substrate has a second thickness, and the second thickness is greater than the first thickness. 15. The apparatus of claim 13 in which the base means further includes a support base, and the first substantially clear film substrate is disposed on the support base. 16. The apparatus of claim 1 in which the base means includes a first grooved surface, and the metallized layer means includes a first metallized layer secured to the first grooved surface. 17. The apparatus of claim 16 in which the base means includes a second grooved surface, and the metallized layer means includes a second metallized layer secured to the second grooved surface. 18. The apparatus of claim 17 in which the first and second metallized layers are secured together to define a single radiant barrier block. 19. The apparatus of claim 18 in which the base means further includes a first rectangular block and a second rectangular block, and the first grooved surface extends diagonally on the first rectangular block and the second grooved surface extends diagonally on the second rectangular block. 20. The apparatus of claim 1 in which the base means includes a first mesh layer. 21. The apparatus of claim 20 in which the base means further includes a second mesh layer, and the metallized layer means is secured to the first and second mesh layers.
