Blackout curtain fixing involves installing heavy, opaque curtains designed to block out light and provide privacy. The process starts with measuring the window to ensure the curtains fully cover it, often extending slightly beyond the frame for maximum light blockage. A sturdy curtain rod or track is mounted securely, as blackout curtains are typically heavier than regular ones. The curtains are then hung using hooks, rings, or directly onto the rod, ensuring they hang evenly and overlap slightly in the middle to prevent light leaks. Proper installation ensures an effective, polished look while improving insulation and reducing outside noise.
