Abstract: 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.
