day night shades

My low tech way cost $1.50 per window. At the end of the season I purchased some fan fold aluminum coloured sun shades (two different sizes available). In addition, I purchased the kind of sun shades that twist up, are black on one side, silver on the other. They were a bargain at two for $1.50. It depends on the window to which style I use.

I carefully slip these behind the day/night shades. They not only block the light, but also help to insulate from the cold or heat.
