Apparently only I knew there are two different grades of glass. Though the boxes are marked as to what the glass is, those labels did not mean anything to my installer or his helper. One of the Super e-glass boxes was opened and five of the six glass panels were removed. At least three of those panels were used in the front wall where they should have been used only on the roof. Its a good thing I thought to check the boxes yesterday before more could be used incorrectly. Looking at the glass, I cannot tell what's what. I took a black magic marker and wrote "SIDE" AND "ROOF" on those still unopened boxes so this could not happen again. My installer and I will have a chat this AM.
