This blackout single curtain panel blocks most outside light, offers noise reduction, and features thermal insulation to help save on energy costs and increase privacy. Made from polyester, it shows off a traditional geometric trellis pattern in muted gray-and-white tones for a classic look we love. Metal grommets are sewn onto the header, making it easy to hang on curtain rods with a diameter up to 1.5" (sold separately). A liner or backing are not included.
