Made with our proprietary YarnLock Seal Technology Yarns receive a unique fleece application that seals gaps in fabric and creates an increase in thermal resistance and insulation for the home, while also providing room darkening benefits. Beautiful white face fabric matches behind any curtain color and white backing is perfect for making curtains compliant with neighborhood association requirements. Liners can be used with clip rings, on a rod pocket pole, and with the use of drapery hooks. Extra wide liner provides more coverage for windows, allowing you to open and close your curtains as you normally would. 100% Polyester. Sold as a single liner. Easy care, machine washable.
