Is condensation between panes a problem with 26-116

Question

I want to add window sash lift handles (26-116) to our thermo pane windows, but I'm concerned about introducing condensation between the panes when I screw the handles on. Should I be concerned?

If the screws are too long, you could accidentally crack the glass, which would definitely lead to condensation. Besides that, the handle installation shouldn't cause any glass failure. Just be wary of where you drill and you should be good to go.
