What is claimed is: 1. The apparatus for retaining an impact resistant window within a frame, said impact resistant window includes a window pane and a film adhesively secured to said window pane, said frame includes a substantially U-shaped groove having a plurality of legs and extending around an inner perimeter of said frame for positioning said impact resistant window within said frame, each said leg of said U-shaped groove included at least one elastomeric member positioned therein and cooperating with said impact resistant window sealing said impact resistant window within said frame; said film extends along a surface of said window pane but does not extend over said at least one elastomeric member; one or more window bolsters having a total length substantially equal to said inner perimeter of said frame, said one or more window bolsters being separate and distinct from said at least one elastomeric member, said window bolsters including a first bead of adhesive, said first bead of adhesive providing securement of said bolster to said frame, said bolster including a second bead of adhesive, said second bead of adhesive bonding said impact resistant window to said one of more of said window bolsters, said impact resistant window is structurally bonded to said one or more of said window bolsters and said one or more of said window bolsters are structurally bonded to said frame; said one or more window bolsters each include an integrally formed first adhesive channel, said first adhesive channel is constructed and arranged to control flow of said first bead of adhesive providing securement of said bolster to said frame; said first adhesive channel includes at least one air conduit allowing air to flow to said first bead of adhesive curing said first bead of adhesive, said at least one air conduit extends the length of said one or more bolsters; said one or more window bolsters each include an integrally formed second adhesive channel, wherein said second adhesive channel is constructed and arranged to control flow of said second bead of adhesive for securement of said bolster to said frame; and said second adhesive channel includes at least one air conduit allowing air to flow to said second bead of adhesive curing said second bead of adhesive, said at least one air conduit extends the length of said one or more bolsters. 2. The apparatus for retaining an impact resistant window within a frame as cited in claim 1 wherein said bolster includes at least one integrally formed support leg, wherein said at least one support leg is constructed and arranged to cooperate with a first adhesive channel to maintain a predetermined thickness of said adhesive between said first adhesive channel and said frame. 3. The apparatus for retaining an impact resistant window within a frame as cited in claim 2 wherein said bolster includes a pair of integrally formed support legs, wherein said pair of support legs are constructed and arranged to cooperate with said first adhesive channel to maintain a predetermined thickness of said adhesive between said first adhesive channel and said frame. 4. The apparatus for retaining an impact resistant window within a frame as cited in claim 3 wherein at least one of said support legs include an integrally formed foot, wherein said foot has an increased cross section with respect to said pair of support legs, wherein said foot is constructed and arranged to disperse loads exerted on said bolster across an increased area of said frame. 5. The apparatus for retaining an impact resistant window within a frame as cited in claim 2 wherein said adhesive includes elastomeric properties for absorbing impact delivered to said bolster. 6. The apparatus for retaining an impact resistant window within a frame as cited in claim 1 wherein said bolster includes an integrally formed impact absorber arm, wherein said impact absorber arm is constructed and arranged to maintain a predetermined thickness of said adhesive between a second adhesive channel and said impact resistant window. 7. The apparatus for retaining an impact resistant window within a frame as cited in claim 6 wherein said adhesive is about three sixteenths of an inch thick. 8. The apparatus for retaining an impact resistant window within a frame as cited in claim 6 wherein said adhesive includes elastomeric properties for absorbing impact delivered to said bolster. 9. The apparatus for retaining an impact resistant window within a frame as cited in claim 1 wherein said bolster includes an integrally formed impact absorber arm, wherein said impact absorber arm is constructed and arranged to dissipate loads exerted on said bolster from said impact resistant window. 10. The apparatus for retaining an impact resistant window within a frame as cited in claim 1 wherein said bolster includes at least one crumple zone, wherein said crumple zone is constructed and arranged to dissipate and redirect impact loads encountered by said impact resistant window. 11. The apparatus for retaining an impact resistant window within a frame as cited in claim 10 wherein said at least one crumple zone is an integrally formed thin section. 12. The apparatus for retaining an impact resistant window within a frame as cited in claim 1 wherein said bolster includes at least one frangible connecting link, wherein said at least one frangible connecting link is constructed and arranged to dissipate and redirect impact loads encountered by said impact resistant window. 13. The apparatus for retaining an impact resistant window within a frame as cited in claim 12 wherein said at least one frangible connecting link is an integrally formed thin section which connects an impact absorber arm and said first adhesive channel.
