Woven Insulated Curtains are Energy Saving Thermalogic Draperies that have No foam backing bonded to them and No separate layer of lining attached to them. Woven Thermalogic Curtains are just one layer of fabric, thus they are the same color from the back side. Their Insulation value comes from a special weave of the fabric. Most of these Thermal Panels are Woven Jacquard, like Belgique, Darcy, etc. Navar is Woven Faux Suede.
