100% Blackout Curtains for Bedroom (Black / 21"W x 78"L (Pack of 1))

⭐ Key Features

•100% Blackout - Made of ultra-dense triple-layer polyester fabric and integrated with innovative nano-coating technology, these blackout blinds block all sunlight, UV rays, and artificial light sources. The innovative coating reflects 135% of heat, ensuring a cool environment while creating a pitch-black space. They are ideal for shift workers, nurseries, and those prioritizing privacy, as they transform any room into a serene, light-free haven

•Upgraded Hook & Loop Installation - Featuring industrial-grade Hook & Loop tape, no drilling or professional tools are needed. Simply fix the patches on the window frame (suitable for both flat and curved surfaces), align the window curtains, and press to complete the installation in just a few minutes. For creases, iron at 120℃–195℃ with a cloth to maintain the durability of the fabric and fastener

•Multiple Sizes Available - Offering a range of width and height specifications to precisely fit various window types, from small bathroom windows to standard bedroom windows and large living room floor-to-ceiling windows. It is recommended to choose a width 2–5 inches wider than the window and a length with a 1–2 inch drape. Combined with the hook-and-loop tapes to seal the edges, it achieves 145% light-proof shading

•Dual-Function Thermal & Noise Control - The dual-layer design features a silver reflective layer that repels 90%+ solar heat (providing 5–8℃ summer cooling) and a black core that reduces winter heat loss by 30%. With 10–60dB noise dampening, it creates a quieter, climate-controlled space for urban living, nurseries, and bedrooms

•Full-Scene Portable Application - The blackout curtain is compact and lightweight when folded, suitable for carrying during travel, camping, or temporary hotel shading. It supports multi-panel hook-and-loop splicing with a 50 cm overlap to cover extra-wide windows. Whether for bedroom sleep, living room movie viewing, office partitions, or RV space renovations, it meets diverse scene requirements

⚠️ Safety Warning

Surface Preparation Before Installation: 1. Clean the window frame thoroughly with alcohol wipes or a damp cloth to remove dust, grease, or stains. (Avoid soap water/cleaners, as they may leave a slippery residue.) 2. Ensure the surface is completely dry before applying. (Allow at least 30 minutes of drying time in humid environments.) Rough surfaces (e.g., diatom mud, sand-textured walls) may reduce adhesion – smooth materials (glass, tile, metal, latex-painted walls) are recommended. Size Measurement & Cutting Guidelines: 1. Width Selection: Curtains must cover 2–3 inches beyond both sides of the window frame. (Recommended: 4–6 inches wider than the window to prevent light leakage.) 2. Cutting Instructions: Use a straight edge to cut along fabric edges (do not tear). Fold raw edges after cutting and secure with hook-and-loop tape to prevent fraying. Temperature & Care Restrictions: 1. Ironing Limits: Use only medium-low heat (120–150℃) and always place a thin cotton cloth between the iron and fabric. (Direct heat may melt or discolor the coating.) 2. Wash in cold water by hand or use a gentle machine wash (place in a laundry bag). Avoid bleach or strong alkaline detergents. 3. Do not tumble dry or expose to direct sunlight. (Prolonged sun exposure may accelerate coating aging.) Air dry flat.
