I have a simple question about putting up Bubble foil insulation on windows with screens. I haven't been removing the inner screens, but simply putting the Bubble foil insulation behind the window shade. This makes it easier to remove the foil when wanted. It seems to be working but am I missing out on some R value protection by doing it this way? thanks
