What Defines a 100% Blackout Curtain Fabric?

A true 100% blackout curtain fabric ensures zero light penetration. In the wholesale market, this is typically achieved through multi-layer constructions. For commercial projects, such as hotels or conference rooms, this level of light blocking is non-negotiable. Browse our blackout collections here.

Common Constructions in the B2B Market

We supply several main types of blackout fabrics:

• 3-Pass Coated Fabrics: A foam coating applied in three layers (white-black-white or similar) to the back of a base fabric. This offers 100% light block while keeping the front face soft and decorative.
• Woven Blackout (Dimout): These use a high-density black yarn woven into the middle layer. While extremely soft and durable, they typically reach 90-95% dimout. However, advanced weaving techniques can push this closer to 98%.
• FR (Fire Retardant) Blackouts: Essential for public spaces. Our FR blackouts meet international standards like NFPA 701 or BS 5867.
