Sleep deeper. Pay less for power. Hear less of the world outside.
Most "blackout" curtains let light bleed through the seams. Most "soundproof" curtains barely soften an echo. The KK1145 is built for people who want all three jobs done at once — total darkness, lower energy bills, and a quieter room — without a contractor or a renovation.
How it works Three layers of dense, tightly woven fabric stop light, slow heat transfer through the window, and absorb mid-frequency sound reflections inside the room. Heavier than a standard blackout panel, lighter than acoustic theater drapes. Hangs on any standard curtain rod.
99.9% Light blocked Tested in a sealed bedroom at noon. The room reads pitch black to the human eye — ideal for shift workers, night-shift parents, and home theaters.
~25% Energy savings Thermal lining slows heat loss in winter and heat gain in summer. Independent studies on insulated curtains show heating & cooling savings up to 25%.

Frequently asked questions (click to expand ▾) Is this curtain truly soundproof? It is sound-dampening, not soundproof. It reduces echo inside the room and softens outside noise like traffic, voices, and lawnmowers. For studio-grade soundproofing you'd also need to seal the door and treat the walls.

How much light does it actually block? 99.9% through the panel itself. To get total darkness, mount on a wraparound rod and let the panel overlap the window frame by ~6 in (15 cm) on each side — that closes the gap where most curtains leak light.
Will it really save up to 25% on energy? Yes — up to 25% on heating and cooling, based on independent studies of insulated curtains. Real-world savings depend on your window, climate, and how much sun the room gets. The thermal lining is real either way — you'll feel the temperature shift within an hour of hanging it.
What do I need? (US & metric) Match width to your window plus 6 in (15 cm) on each side for full light seal. For length, floor-length panels block more light and look better than mid-length. If you're between s, go up. Need exact fit? servicearrowzoom.com.
How heavy is it? Will my rod hold it? About 3.3 lb (1.5 kg) per panel for the Wide-Tall — heavier than a standard blackout curtain because it's three layers thick. Use a metal rod (not plastic) and anchor brackets into a stud or with proper drywall anchors. A standard 1 in (25 mm) rod is fine.
Can I wash it? Yes — cold gentle cycle, mild detergent, low tumble or hang dry. Don't bleach. Don't iron the thermal lining directly.
Is the fabric safe / non-toxic? Yes. The fabric is OEKO-tested and free of harmful chemicals. Safe for nurseries, kids' rooms, and bedrooms.
