Ballistic assault barrier system

Abstract

An armored window system can include a window frame; a glass pane positioned in the window frame; a first fragment retention film attached to a first side of the glass pane; a second fragment retention film attached to a second side opposite the first side of the glass pane; at least one layer of foam tape adhered to the second fragment retention film; and a layer of polycarbonate adhered to the at least one layer of foam tape. A silicone based sealant can be applied to fill any gaps between the frame and each of the second fragment retention film, the at least one layer of foam tape, and the layer of polycarbonate.

         8 . The armored window system of  claim 1 , wherein:
 the second fragment retention film is separated from the frame by approximately a sixteenth of an inch.   
     
     
         9 . The armored window system of  claim 1 , wherein:
 the first fragment retention film is separated from the frame by approximately a sixteenth of an inch; and   the second fragment retention film is separated from the frame by approximately a sixteenth of an inch.   
     
     
         10 . The armored window system of  claim 1 , wherein:
 the at least one layer of foam tape is separated from the frame by approximately a sixteenth of an inch.   
     
     
         11 . The armored window system of  claim 1 , wherein:
 the layer of polycarbonate is separated from the frame by approximately a sixteenth of an inch.   
     
     
         12 . The armored window system of  claim 1 , wherein:
 the first fragment retention film is at least partially transparent;   the second fragment retention film is at least partially transparent;   the at least one layer of foam tape is at least partially transparent; and   the layer of polycarbonate is at least partially transparent.   
     
     
         13 . The armored window system of  claim 1 , wherein:
 the glass pane has a thickness of approximately a quarter of an inch.   
     
     
         14 . An armored window system comprising:
 a window frame;   a glass pane positioned in the window frame;   a first fragment retention film attached to a first side of the glass pane;   a second fragment retention film attached to a second side opposite the first side of the glass pane;   at least one layer of foam tape adhered to the second fragment retention film; and   a layer of polycarbonate adhered to the at least one layer of foam tape, wherein an air gap is positioned between the second fragment retention film and the layer of polycarbonate.   
     
     
         15 . The armored window system of  claim 14 , wherein:
 the first fragment retention film has a first thickness in the range from approximately 8 mils to approximately 23 mils; and   the second fragment retention film has a second thickness in the range from approximately 8 mils to approximately 23 mils.   
     
     
         16 . The armored window system of  claim 14 , wherein:
