For an inexpensive alternative to solar drapes, go to a camping store and buy emergency solar blankets. Tacky glue can be used to make a pocket for a tension rod to slip through. Fold the solar blankets to the length needed and then make the pockets for the tension rod. The new solar curtain can be put up behind the existing blinds or drapes.
And if you want to keep the heat in or out pelmets are a good idea too - www.yourgreendream.com/
Thank you so much for the great idea. I have used foil before but this is a fantastic idea.
Have a great cool summer!
Awesome, creative suggestion! I will try it. These tough economic times do indeed evoke creativity and bring to mind the saying that goes: "...necessity is the mother of invention." Thanks!
