I think I'm going to try the foam and wrap the edges with gorilla tape, not very expensive. The side window will stay in place, the cab window sheet will be stored by the side window. Probably won't carry there cab insulation except in winter.
I'm think on only using 1/2" thick, with an R value of a little more than 3, but shouldn't stick out much if I cut it to fit inside the metal window frame.
Thanks for the suggestions.
The metal frames of the windows conduct a significant amount energy themselves. In my environment that's not a huge deal, but if I was dealing with really cold weather, I'd be inclined to position the board on top of the frame, overlapping enough to place a foam weather seal all the way around the edge of the foam board. Again, at mid to low 20s, the Reflectix solution worked just fine. I didn't feel the need to dive back into the covers with a stocking cap on after the middle of the night pee.Wallowa said:Good plan. Get up in middle of night to pee? Yup, like clock work.
What brand of foam board are you folks using? Can you buy it online?
Thanks...Phil
