Types of Curtain Lining: How to Choose the Right Option

Curtain lining is an additional layer attached to the back of a curtain panel. It can improve light control, privacy, insulation, fabric protection and drape. REGAL offers three primary options: unlined curtains for a lighter appearance, 90% blackout lining for strong light reduction, and 100% blackout lining for maximum light blocking through the fabric.

Choose unlined curtains when you want more natural light or when the main fabric already provides the required opacity. Choose 90% blackout lining for balanced light control and insulation. Choose 100% blackout lining for bedrooms, nurseries and home theaters where maximum darkness is the priority.
