Since the increase in energy prices, many people are wondering what to do about their inefficient windows. The windows can be a significant area of heat loss.
It would be nice to call a contractor and have all the windows replaced with new ones, but that can be a very expensive proposition. There is another step homeowners can take that will save energy.
Installing insulated shades or curtains is an excellent way to improve the efficiency of older windows. A single-pane window has an insulation value of R-1. The insulation value of the best insulated window shades is R-6. They also reduce drafts.
The Roman shade is popular and efficient because it can be quite thick. The best ones have four insulating layers, including reflective, Mylar, and a vapor barrier in the center. A magnetic-edge strip is used so they seal well against the wall.
You can also add your own material to the shade so it will complement your decor. Kits include special adhesive strips that are activated with a steam iron. If you are handy with sewing, you can sew your own material onto the shade.
