Breakages during Heat sock test

I have serious problems with HST, because all my glass plates break during the process (every 100 plates 80 are broken). The plates are 1500 x 2500 mm, glass tickness is 12 mm, the holes are D=12mm and are 24mm distant from the long sides. There are total 8 holes. At the corners the holes are 160mm and 30mm distant (from the edges). During the tempering process all is OK. In the HST process during the cooling phase the glass break.

I don't know if the problem is the tempering process or maybe the position and the diameter of the holes.What do you suggest me?

Low E Glass in Single Glazing

I am a developer in India and making a huge commercial project of 1 million sqft. We want to use hard coated low e glass in single glazing. Ours is a dry and hot climate, where temperature varies from 35 to 45 degrees most time of the year. Can we use low e glass in single glazing and will it give the required performance in single glazing ?
