Blackout Veri Shade

Because "blackout" describes the fabric, not the installation. The cloth itself passes no light, but a blind mounted inside the reveal must be cut a few millimetres narrower than the opening in order to move, and daylight finds that gap. If total darkness is the goal, mount outside the frame with a two to three inch overlap on each side and a deeper drop below the sill. Say so before we measure and we will size it that way from the start.

Not if it is the right type. Anything that rolls down in one piece has to be raised every time you walk through, which nobody keeps doing. Vertical blinds and veri shades draw sideways instead, so the panels stack at one end and the doorway is clear while the rest of the glass stays covered. Tell us which side you walk through and we will set the stack on the other one.

It depends on the mechanism, and every product page states its own limit in the specification table. Vertical blinds and veri shades go widest because the weight hangs from a track rather than winding onto a tube. A roller past about eight feet has to be made as two blinds sharing one bracket line — the calculator says so as soon as you enter a width that needs it, rather than surprising you on installation day.

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. Tell us which you want and measure accordingly — our /measure guide walks through both with the exact points to record.
