Experience the darkness, silence and beauty of Eclipse curtains, without parting with your existing curtains. Eclipse Thermaliners bring your existing curtains from fashionable to functional. Eclipse Thermaliner panels have been laboratory-tested to block over 99% of outside light, unwanted noise, and can help to save on home heating and cooling costs. National Sleep Foundation studies show that blocking unwanted light and noise while you sleep helps create the optimal sleeping environment. Transform any room in your home with Eclipse Thermaliners. Hang them with your existing curtains in your media room for the ultimate home theater experience, or in your dining area to create an intimate date night. Add Thermaliners to any curtain to block the cold from entering your home through drafty windows and help keep hot sunrays out in the summer. Eclipse Thermaliners are perfect in the bedroom, kid's room or nursery to create the ideal sleep environment for the whole family. Blackout liners are versatile and can be attached to any window curtain using easy-to-use hooks included; or hung from a separate rod. Rod pocket fits up to a 1.5 in. diameter rod. Rod not included. When attaching the Thermaliner to your curtains, stagger the hocks, allowing the face curtain to gather in between each hook. The Thermaliner is narrower than the curtain width to allow for the natural gathered effect of the curtain. Each Thermaliner panel measures 27" wide to fit panels up to 54" wide. Available in your choice of 60," 80, or 92" lengths. Each package contains two 27" panels. 100% Polyester. Easy care - machine wash, tumble dry, do not bleach. Imported.
