Blackout fabric is a curtain fabric that has been made opaque through special coatings or weaving techniques, offering complete light-blocking properties. With its ability to block 100% of sunlight and external illumination, it improves sleep quality, saves energy, and provides privacy.

Blackout fabric, produced in a weight range of 200–400 g/m², typically features a three-layer structure (outer surface + blackout layer + inner surface). Premium types that also provide sound insulation are available. Its moisture and dirt-repellent properties make it easy to maintain.

Used as curtains for bedrooms, nurseries, cinema rooms, and offices, blackout fabrics are offered by Çerçiler Kumaş in plain color options, 280–300 cm wide, per meter.
