Blackout vs Dimout Fabrics for Hotel Guest Rooms

Both blackout and dimout fabrics reduce light in guest rooms, but they do different jobs and suit different rooms.

Blackout

Blackout fabrics are designed to block light almost completely. Common constructions are two-pass or three-pass coated fabrics. They suit rooms exposed to street light or strong sun, and guests who need a dark room to sleep.

Dimout

Dimout fabrics soften daylight and reduce glare while keeping the room feeling bright and airy. They suit rooms where total darkness is not wanted or where a lighter feel is part of the design.

Choosing for a hotel

• Room orientation: sun-facing or light-exposed rooms usually need blackout.
• Layering: many hotels pair a sheer with a blackout or dimout drape for flexibility.
• Edge light: fullness, side returns and track design affect light leakage as much as the fabric.
• Handle and weight: coated blackouts can feel stiffer, so check drape on a sample.

Fire performance is separate

A fabric being blackout or dimout says nothing about its flame retardancy. Blackout is not automatically IFR, and compliance depends on the construction and test evidence for the exact article. State the required standard in the specification (see our guides to BS 5867-2 and NFPA 701).
