100% BLACKOUT & UV PROTECTION: The inner lining features a unique dual-layer construction, white sheer fabric bonded to black TPU backing, creating a grey composite that optimizes light blockage. This specialized structure effectively filters UV rays while significantly reducing light penetration, maintaining darker room conditions for better rest. The design also helps protect interior furnishings from sun damage. BUILT-IN TIE-BACKS: Each panel features 25.6-inch tie-backs sewn directly onto the curtains. Easily control light by fastening or loosening the ties - no need to purchase separate accessories. THERMAL INSULATED & SOUNDPROOF: The heavyweight fabric creates an effective barrier against outdoor temperatures, keeping your room cooler in summer and warmer in winter. Its dense construction also helps absorb outside noise for a more peaceful living space. CARE INSTRUCTION: Machine washable (hand wash recommended) or spot clean with a damp cloth. Air dry only - do not bleach or tumble dry. You can gently iron the outer fabric on low temperature if needed to smooth out wrinkles. 100% BLACKOUT & UV PROTECTION: The inner lining features a unique dual-layer construction, white sheer fabric bonded to black TPU backing, creating a grey composite that optimizes light blockage.
