Thanks for posting. Some Nu-Air windows use glazing like our 55-029, but I can't be certain this is what you need without seeing a sample. I advise you compare the end profile illustration below with the glazing remaining on this window or from an identical window to see if it matches what you have. If anything differs, let me know in what way. Profile diagram of 55-029
