Cased Duette Blind

In the cased system the double-layer honeycomb travels up and down inside side channels; the rail is both guide and closure. The edge gap is covered by the rail — the only line seen from outside is the cassette and rail.

The closure produces two performances: edge light leak falls to the lowest allowance, and the air current around the two nested cells is braked so the barrier turns unbroken. On the open-edged arrangement the cells are open to air exchange at the edge; in the cased they are not.

The rail profile seats to the joinery’s bead plane or inside the casing; permanent installation is made with screwed mounting.

It is the bedroom’s natural match: the enclosed rail covers the edge lines, the double cell raises two buffers on the glass plane — morning light does not appear as a line, winter-night glass chill does not enter.

In meeting and presentation rooms edge leakage in front of the projection disturbs; the cased system provides visual cleanliness.

On frequently opened windows rail protection shields the fabric from side impact; fabric life lengthens over the open-edged system. For the thin single-cell alternative the cased honeycomb blind is described on a separate page.
