We are in a low-rise building, twelve storeys with window wall, and a taller component, of fifteen storeys with curtain wall. Our just completed Reserve Fund study, including consideration of the small amount of initial post-construction fall-out over the past few years, forecasts a window system lifespan, before complete refurbishment of the window and curtain wall components is needed, of 45 years.
This may not be typical of high rise towers, as my understanding is that building flex is one of the key contributors to window seal failure, however I suspect that the 10 - 20 years number is just someone's (perhaps) wild imagination.
