Window pane systems which offer improved protection against blast and impact hazards, including contact blast caused by a bomb or a shell, with or without hollow charge and bullets. A window pane system of the present invention includes multiple glass layers, to absorb the ballistic impact of the explosion; a thick polymer such as polycarbonate, to absorb the kinetic energy of the blast including contact blast; and multiple elastic thin layers of polymer such as polycarbonate, to absorb the blast impact such as the shock wave and shrapnel. Optionally, the last layer is extended such that the last layer is covering up to the full width of the window pane system, preferably in all four sides of the window pane system.

1. A window pane system, comprising: multiple layers of glass sheet;a thick layer of elastic and transparent material adhered to at least one of the multiple layers of glass sheet;two or more thin layers of elastic and transparent material; anda gap disposed between the thick layer and the two or more thin layers so that the thick layer is configured to move inside the gap to absorb part of an impact of a blast;wherein the last thin layer of the two or more thin layers is adhered to another of the thin layers via an adhesive layer and the last thin layer comprises at least one folding part configured to wrap one or more sides of the window pane system, whereby said last thin layer provides an increased absorption capacity for the blast. 2. The window pane system of claim 1, wherein the window pane system has sufficient capacity to absorb the impact of the blast, and wherein the window pane system has sufficient capacity to substantially reduce an effective angle of a destructive movement of a liner created by detonation of a hollow charge. 3. The window pane system of claim 1, wherein said elastic and transparent material of said thick layer is selected from the group of polymers including Polyester, Polycarbonate and Acrylic. 4. The window pane system of claim 1, wherein said elastic and transparent material of each of said two or more thin layers is selected from the group of polymers including Polyester, Polycarbonate and Acrylic. 5. The window pane system of claim 1, wherein said glass layers have sufficient capacity to absorb the ballistic impact of said blast. 6. The window pane system of claim 1, wherein said thick layer has sufficient capacity to absorb the kinetic energy of said blast including contact blast. 7. The window pane system of claim 1, wherein said thin layers have sufficient capacity to absorb said blast shock wave and shrapnel. 8. The window pane system of claim 1, wherein all of said layers are adhered to each other by glues. 9. The window pane system of claim 8, wherein said glues are selected from the group of materials including Polyvinyl Butyrel, Polyurethane, Acrylic, SentryGlas, Noviflex, Ethylene Vinyl Acetate and Epoxy. 10. The window pane system of claim 8, wherein said glues increase the overall elasticity of the window pane system. 11. The window pane system of claim 1, wherein said gap is filled with gas which is treated to prevent condensation. 12. The window pane system of claim 11, wherein said gas is air. 13. The window pane system of claim 1, further including a slat armor device, wherein said slat armor device is disposed in front of the window pane system with respect to a flying path of a hollow charge device. 14. The window pane system of claim 1, wherein the multiple layers of glass sheet are directly bonded to each other.
