We've updated our classic insulated window treatments with curtains that have a more attractive finish, substantial weight and a softer feel. ThermalogicTM Energy Efficient Insulated Tab-Top Curtains are made of 100% cotton with a rich, woven texture similar to sailcloth. Each is backed with a lining of 100% acrylic foam that creates a barrier against sunlight and drafts, helping you maintain a constant room temperature year-round. Foam backing blocks out up to 95.3% of light, reduces outdoor sound by up to 46.3% and reduces heat loss as much as 44%. These drapes have white backs, and are great for protecting carpets, eliminating unwanted noise and reflections. Imported. ThermalogicTM triple stripe curtains. Money-saving insulating layers.
