Microfiber Blackout Thermal Insulated Eyelet Curtains: Experience the darkness, silence, and beauty of Blackout Curtains. Microfiber blackout panels have been laboratory-tested to block out over 99 percent of outside light, and up to 40 percent of unwanted noise and can help to save up to 25 percent off home heating and cooling costs, combining functionality with the versatility and style needed to enhance any room in your home. Hang them in your media room for the ultimate home theatre experience, or in the dining area to create an intimate setting. Perfect in the bedroom, kid's room, or nursery to create the ideal sleep environment for the whole family. National Sleep Foundation studies show that blocking unwanted light and noise while you sleep helps create the optimal sleeping environment. The magic is in the Thermal weave construction. The innovative triple-weave design allows you to enjoy light-blocking, noise-reducing, and energy-saving benefits while providing the same style and elegance of naturally flowing curtains.
