Tim,
I hope you're right. I am only going by what other have told me, but they could have installed them wrong. I just look at the 60 year old design and think to myself, 'man, you could drive a mack truck between the two panes'. Yes, there's felt there and it creates a seal, but nothing like a single pane could do.
49 bourbon, I think i'm good. I am going back to the sliders, but thanks
