Sunscreen Zebra Blind

Yes, and this surprises people. Sunscreen mesh works by contrast: in daylight the bright side is outside, so you can see out and passers-by cannot see in. After dark the bright side is inside and that reverses — with the lights on, silhouettes are visible from the street. For a street-facing bedroom or a ground floor, pair sunscreen with a blackout blind on the same window, or choose a light-filtering fabric instead.

The fabric is one continuous loop with alternating sheer and solid horizontal stripes, running over a roller tube. Pulling the chain moves the front layer against the back layer. When solid sits over solid, the window is closed and light drops to a dim glow. When solid sits over sheer, you get an even band of filtered daylight across the whole window instead of a single gap at the top or bottom, which is what makes it more useful than a plain roller in a room you use all day.

Every fabric fades eventually under direct sun; the question is how fast and how evenly. Solution-dyed polyester and sunscreen mesh hold colour far better than printed cotton-look fabrics, and mid tones show fading less than deep navy or black. A west or south-west window is the harshest position in a Dhaka flat, so if that is where the blind goes, choose a lighter mid tone and expect the visible side to soften slightly over several years rather than patch unevenly.

Lower the blind fully and go over both faces with a vacuum brush head or a dry microfibre cloth, top to bottom. Do that monthly and Dhaka dust never builds into a grey film. For a mark, dab with a barely damp cloth and mild soap, then leave the blind down until it is completely dry — rolling up a wet blind is what causes streaks and a musty smell. Never soak the fabric, never scrub, and never machine-wash a blackout blind: the coating on the back is what blocks the light and it will crack.
