Just a few tidbits of major FUBAR glass jobs of the planet = (1) most often fuckup is at glass processor (the factory that takes giant stock sheets and converts those into glazing lites to be installed) and they can do that several ways. (2) Then major fuck #2 is architect who draws something fancy but fuck Engineer (people like me) and Glazier have no damn idea how to pull it off. (3) #3 then is glazier who installs and not much brighter than a smart monkey. Axiom = "glazing is a very angry trade" and I so wish I had never fallen into it for now for me at 44 years of it actually just past 20 years there's no turning back.
