Double up on the double pane glass = savings

MetroMPG is thinking about doing this as well. My main concern would be moisture build up between the two windows. You'd ideally want to vacuum the space between the windows or something to get the moisture out of there. There is also the fact that doing this will reduce the VT (visual transmittance - the amount of light you get) through the opening. Otherwise, it should work rather well. Its basically the principle of the super high performance windows like Serious windows where they have 2 panes of glass and multiple sheets of plastic between the glass to create more chambers in the window to reduce heat loss.

This might be cheaper and would have a similar result, I think. It worked for Guy Mardsen. This is what I want to do.

My neighbor has a 100 year old house with big pitcher windows and he has double pain windows installed on the outside as if they were storm windows, they look great and work great, not sure if they have drains on the bottom or not.

moisture drainage is an issue, I would have the drains open to the outside, that way any fresh air that gets in there will be dryer in those seasons when water could condense and the warm humid air from inside the house never gets in that space, to that point you also want to make sure that the windows are sealed well from warm humid air from the inside, making sure that the trim around the window is even caulked tight, everything is painted well and that the sill is not rotting.

Other option that might work is a tiny solid state dehumidifier in each space, you can buy a whole unit for $40 or buy the parts for about $15.

Unless he put the windows in upside down they would have the vents on the bottom( my neighbor hired a guy who installed his bathroom window upside down). Which has giving me good ? idea .
With the 2nd window mounted on the inside the vents would drain inside the house, if it was to condensate in between the two windows.
But if i mounted it upside down it may allow the windows to breath a tiny bit. From the outside bottom vents threw to the inside reversed drain holes
at the top, and prevent condensation. My theory, it would have to be actually done to know.

I have just remembered I have two twin 4x5ft full double pane windows giving to me by a neighbor who did not use them, instead opting for windows that could open. I could remove one window from the living room, put it on the inside of the other matching window and install the two free matching windows together. So i could have two 4x5 windows double double paned for free, or next to it.

That would work well, The costs to do each of my three 4x5 windows would be $25 @ $1.25 sq.ft
The construction would be simple enough.

The double pane window would be easy and have a higher R value then the plastic window build. It would be a two man job, windows towed behind my Car on the utility trailer. They would fit in my window openings with no modification needed(standard size opening) just require proper sealing of the windows frame with the houses window opening.
It is superior ,IMO. But I still like your idea, it could be done by someone without a vehicle / spare cash or anyone to help move/install the windows.
A good option.
