Light Filtering Honeycomb Blind

The mechanism is real: the cells hold a layer of still air against the glass, and still air is a poor conductor, so heat crosses the window more slowly. What that is worth depends on your window — a west-facing pane in full afternoon sun benefits far more than a shaded north window, and a double-cell fabric does more than a single. It is a genuine improvement in comfort and AC cycling, not a replacement for the AC.

More than a roller, because the folds stack rather than wind onto a tube. On a tall window the stack can be a hand-span deep when the blind is fully raised, and that stack sits over the top of the glass unless the blind is mounted above the opening. If the reveal is shallow, mount it outside the frame or choose a honeycomb blind, which folds much flatter.

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.
