I buy glass every now and then to build missing storm sashes in my old house (ever continuing fix up projects), picture framing or other projects. I have noticed what they call "single strength" has gotten a sliver thinner. Not as thin as the small photoframe stuff though. It is not that hard to see the difference if you bring to pieces together. I'm sure I'm not comparing it with double strength because DS is quit noticably thicker and heavier. Seems like the makers are skimming to lower materials cost.
