This winter, try thermal drapes.  The shading technology that eliminates up to 90% of light, and keeps height from escaping your residence. 

Whether you are talking about insulating the walls of your home or insulating your curtains, insulation is measured using what is called the R-value. The higher the R-value, the better the insulation quality of the material. R-values typically range from 0 (open air) to attic insulation (which has an R-value of up to 60).

Windows also have an R-value. Single pane windows have an R-value of 1, while Energy Star rated windows typically have an R-value of 3. Properly installed, insulated shades can increase the R-value of a window to as high as 6.
