The glass has to be fit for purpose but it may be the fixings that are failing, rather than the glass itself. My block had a problem with the pins holding the glass in place at the bottom of the frame corroding and dropping the glass so that it flipped out at the top. The simplest solution was to add aluminium “lips” at the top. It was still expensive though.
To answer your question, get a building surveyor to examine why the glass failed and then work out if that is likely to be replicated. If you are still within the claims period, get the developer on to it pronto.
