Double up on the double pane glass = savings

[ecomodded]

I am leaning more and more to installing the 2nd window upside down.
The tiny amount of airflow from the outsides window lower drain holes to a flipped upside down 2nd window upper drain holes "should provided the needed breathing room" to prevent fogging.
When a Windows seal breaks allowing moist air in, they fog.
They sell tiny little valves that you install in drilled holes in the glass.
One in a upper corner other in a lower opposite corner.
To allow "some air flow" between the two pieces of glass.
Clearing the fog between the 2 panes.
So i am thinking the tiny drain holes will provide a similar effect.

I am going to read up on the valves and try to understand the function of them better.
I believe the valves are one-way. I will post a link to some information on them.
So we can all see how that "system" works.
Later, I have got to run now.

That doesn't make any sense. If you did this and were circulating outdoor air through the window in the summer, you will fog the inside facing pane of glass because the dew point inside the window would be lower than the temperature inside the house. You'll also get all of the dirty look to go with it too. If you have the indoor air breathe than you will fog the glass in winter and see frost between the panes. You are also going to lose the benefit of having a dual pane window.

Instructions do exist on how to disassemble dual pane glass in a wood frame window, separate the panes to clean them, reseal the glass, and put it back into its frame. It's best for a pro to do it though because if when resealing the glass you don't attach the strip with a perfect seal, you haven't fixed the glass.

Not sure if your factoring all of the aspects.

As i said earlier, one would have to try it to know for sure.Either way.
To discount a theory before actually trying it would be counter productive.
Not going to learn any facts by not trying, that's 4 sure.

Seeing how they have success defogging leaky double panes,already,
I will assume my theory has some weight to it.

As far as protecting air from moisture between the two windows have you considered a desiccant material in that space? Assuming the two windows are fairly well sealed, I'd think it would be able to take care of the issue without compromising the seal to the outside.

[ecomodded]

Generally a desiccant would eventually become useless, once its surface is saturated.
But
In this case it may well be a desiccant would never "fill up" with moisture. So I would say It should work well, even in the long term if I sealed the window frame with a tube of silicone spread with a putty knife.
I could use the Crystals that you use in gardening, and seal them inside.
Not sure how it would stand up to the UV rays.
Perhaps sealing the crystals in a mesh bag would protect them.

Edit:
I Think I would keep the drain holes open to dry out the Crystals on sunny days.
