Light Filtering Roller 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.

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.

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.

Both are valid, and they give different results. An inside (reveal) mount looks tidier and keeps the sill usable, but a little light always escapes at the edges. An outside mount overlaps the frame by two to three inches on each side and is the only way to get a genuinely dark bedroom.
