I recently purchased a house with sears super K (krypton filled)heat mirror windows installed in 1994. We have now had 3 windows explode for no reason. The inner pane of the bottom windows keep breaking. All three windows have been in separate rooms and this occurred at different times. Two in daylight one at night.
There are no signs of settling or movement.
the glass guy who came to repair the windows previously said something must be hitting them, but this is not the case. They are just exploding on their own. I watched one explode across from me tonight. There was a loud pop, and then you see the glass all over the ground. Again it was just the inner pane of the bottom window.
Do you know why this is happening?

Here's a window mans opinion. This is an interesting problem since I once was a glazier. http://www.thewindowman.co.uk/explode.htm
As a former glazer, what would you do? Everything I've read says there is no way to know when it will stop happening, no in my case it clearly has no predictable cause. The windows all were on different sides of the house. One happened in August (when hot) one in October ( when mild) and now one in Noevember( when cooler).
Number one, I would check to see if any of the windows show signs of a vacuum pulling the panes together. Number two, see if the window frames show signs of deteorioration that would stress the glass. I have not seen this problem myself, and I would have just have replaced the glass unit and moved on. I didn't do anything but repairs and replacement of glass and screens, automotive and industrial, storefronts etc.
