Blackout Fabric

Blackout fabric is specially engineered to block 100% of light from passing through, creating complete darkness in interior spaces. This light-blocking capability is achieved through dense weaving constructions, specialized coatings, or multi-layer fabric structures.

Three primary types of blackout fabric serve the market. Three-pass blackout fabric features a foam backing applied in three layers, with a white layer facing the window, a black middle layer for light absorption, and a colored or white layer facing the room. Woven blackout achieves opacity through extremely dense construction, using tightly packed yarns to prevent light penetration without additional coatings. Coated blackout applies an acrylic or other polymer coating to standard fabric to create the light-blocking barrier.

The industry distinguishes between different levels of light control. True blackout fabric blocks 100% of light, creating complete darkness even in bright daylight. Dim-out fabrics block 95-99% of light, suitable for applications where some ambient light is acceptable. Light filtering fabrics reduce light transmission by 50-80%, softening harsh sunlight while maintaining visibility.

Blackout fabrics typically range from 180 to 280 GSM and are produced in widths up to 300cm to accommodate wide window treatments. Many blackout fabrics are available with flame retardant treatments, which are often required for commercial installations in hotels, hospitals, and public buildings.

The primary applications for blackout fabric include bedroom curtains where complete darkness improves sleep quality, hotel window treatments where guests expect effective light control, home theater rooms requiring darkness for optimal viewing, and bedrooms for shift workers who sleep during daylight hours.
