A process of retrofitting an existing window that uses a gasket to secure a sacrificial member and a glazing. The sacrificial member forms a replaceable protective barrier between the glazing and occupants of a vehicle such as a bus. The gasket is traditionally used to secure the sacrificial member and the glazing to the window. Over time, after several removal and re-installations during replacement of the sacrificial member or the glazing, the gasket typically becomes unfit for subsequent use. The gasket is replaced with a rigid retainer member that fits into an existing recess that receives the gasket. The retainer member secures the sacrificial member and the glazing to the window so as to permit repeated changes of the sacrificial member without removal of the retainer member.

1. A method of retrofitting an existing window assembly in a mass transit vehicle with a replacement sacrificial member retention assembly, the method comprising:extracting a rubber gasket from at least one recess formed in a frame of the window so that the rubber gasket no longer retains the sacrificial member adjacent a first side of a glazing of the window assembly, wherein the rubber gasket also no longer retains the glazing in the frame; sizing at least one rigid retainer so as to allow the at least one rigid retainer to be positioned in the at least one recess to thereby be positioned adjacent at least two opposed edges of the glazing; positioning the at least one rigid retainer into the at least one recess in the frame such that the at least one rigid retainer is able to retain the sacrificial member adjacent the first side of the glazing, wherein the at least one rigid retainer is also able to retain the glazing in the frame; and positioning the sacrificial member adjacent the first side of the glazing so as to be retained by the at least one rigid retainer and wherein the at least one rigid retainer is sized such that when positioned in the at least one recess at opposed edges of the glazing, a space is defined adjacent a first edge of the sacrificial member and the at least one retainer wherein the space is sized so as to permit the first edge of the sacrificial member to be moved into the space a distance sufficient to expose an opposing edge of the sacrificial member from an opposing rigid retainer to thereby facilitate removal of the sacrificial member. 2. The method of claim 1 further comprising, prior to positioning a plurality of rigid retainers, positioning a replacement glazing in the frame.3. The method of claim 1, wherein the at least one rigid retainer comprises a first leg sized to fit into the at least one recess in the frame and a second leg that defines the space sized to receive the sacrificial member such that the sacrificial member is secured adjacent the first side of the glazing.4. The method of claim 3, wherein the second leg retains the glazing in the frame by engaging the portion of the first side of the glazing.5. The method of claim 3, wherein the space defined by the second leg is dimensioned such that the edges of the sacrificial member slide within the spaces of the rigid retainers positioned at opposite sides of the frame so as to facilitate removal and positioning of the sacrificial member.6. The method of claim 5, wherein the second leg is further adapted to permit a fastener to extend into the space so as to inhibit sliding of the sacrificial member.7. The method of claim 6, wherein the rigid retainer positioned in the recess in the frame remains in place when the sacrificial member is replaced.8. The method of claim 7, wherein the rigid retainer is formed from a resilient material to permit repeated use as sacrificial member is replaced repeatedly.9. The method of claim 8, wherein the rigid retainer is formed from a metal.10. The method of claim 1, wherein the mass transit vehicle is a bus.11. A method of replacing a sacrificial member of a window in a mass transit vehicle, the method comprising:removing a rubber gasket from a recess formed in a frame of the window so that the rubber gasket no longer retains the sacrificial member adjacent a first side of a glazing of the window; removing the existing sacrificial member from the first side of the glazing; substituting the rubber gasket with at least one rigid retainer that is dimensioned to fit into the recess formed in the frame of the window and retain the sacrificial member adjacent the first side of the glazing; and installing a new sacrificial member such that the at least one rigid retainer retains the new sacrificial member adjacent the first side of the glazing. 12. The method of claim 11, wherein the rigid retainer comprises a first leg sized to fit into the recess in the frame and a second leg that defines a space sized to receive the sacrificial member such that the sacrificial member is secured adjacent the first side of the glazing.13. The method of claim 12, wherein the space defined by the second leg is dimensioned such that the edges of the sacrificial member slides within the spaces of the plurality of rigid retainers positioned at opposite sides of the frame.14. The method of claim 13, wherein installing the new sacrificial member comprises sliding the upper edge of the sacrificial member into the space of the at least one rigid retainer positioned at the top of the frame so as to facilitate positioning of the lower edge of the sacrificial member into the space of the at least one rigid retainer positioned at the bottom of the frame.15. The method of claim 14, wherein the second leg is further adapted to permit a fastener to extend into the space so as to inhibit sliding of the sacrificial member.16. The method of claim 15, wherein the rigid retainer is formed from a resilient material to permit repeated use as sacrificial member is subsequently replaced repeatedly.17. The method of claim 16, wherein the rigid retainer is formed from a metal.18. The method of claim 11, wherein the mass transit vehicle is a bus.19. A method of replacing a glazing of a window in a mass transit vehicle, the method comprising:removing a rubber gasket from a recess formed in a frame of the window so that the rubber gasket no longer retains the glazing in the frame; removing the glazing from the frame; installing a new glazing in the frame; and substituting the rubber gasket with at least one rigid retainer that is dimensioned to fit into the recess formed in the frame and retain the glazing in the frame. 20. The method of claim 19 further comprising, after substituting the rubber gasket, installing a sacrificial member adjacent the glazing such that the sacrificial member is also retained by the at least one rigid retainer.21. The method of claim 19, wherein the rigid retainer comprises a first leg sized to fit into the recess in the frame and a second leg adapted to retain the glazing in the frame.22. The method of claim 21, wherein the rigid retainer is formed from a resilient material to permit repeated use as glazing is subsequently replaced repeatedly.23. The method of claim 22, wherein the rigid retainer is formed from a metal.24. The method of claim 19, wherein the mass transit vehicle is a bus.
