Blackout Curtains vs Dimout Curtains: Key Differences Buyers Should Know

Blackout curtains are engineered to block nearly all incoming light, typically achieving 90%–100% light blocking. This performance is achieved through dense fabric structures, coated backings, or multi-layer constructions. They are commonly used in bedrooms, hotels, hospitals, and spaces where complete light control and privacy are required.

Dimout curtains, by contrast, reduce light intensity without fully darkening a room. They usually offer 60%–80% light blocking, allowing some natural light to pass through. Dimout fabrics are often lighter in weight and provide a softer atmosphere, making them suitable for living rooms, offices, and decorative spaces.

From a buyer’s perspective, choosing between blackout and dimout curtains depends on functional requirements, fabric weight preferences, and cost considerations. Clear product classification helps wholesalers and project buyers select the right solution for different markets and end uses.
