Do you have any pictures of your insulation job? Sounds like a great idea.
Haven't got pics, Spur, but I'll explain how I made the insulating window inserts. One 4 x 8 foot sheet of 3/4 inch foil backed styrofoam insulation board was enough for every window in my 26BH.
First, measure each window for width and height. Carefully cut out the rectangles of insul-board with a sharp utility knife blade, using a carpenter square to keep things, well, square.
Find something that has the same radius as the window corners, like a pot or pan lid, or some other container. I think I found a large yogurt lid that matched. Use the edge of the radius guide to mark the curve of the corners. Again, cut carefully.
After cutting, I went around the entire perimeter of the inserts with duct tape. This prevents the styrofoam from breaking away, and makes the edge stronger. (do a test fit before adding the tape).
The insert should fit snugly into the window frame (foil side out is what I do). Over time, it will fit a little looser. To remove, I just use the point of a knife to gently pry one corner out.
For the egress windows, it's necessary to cut a notch out where the latching mechanism is attached. On my egress windows, I inserted the insul-board and taped it in place. I pretty much leave the insul-board in the egress windows full time.
Hope that gives you some idea on how to insulate your single pane windows. They do work great for keeping heat in or out, whichever you need at the moment. To hold in the heat and prevent condensation, I put mine in in the evening, and remove in the morning after it warms up a little. If a window is in direct sun, it really blocks out the heat well, too.
