# Round Duette Blind

Double-layer honeycomb fan on circular glass. The form-completing cover arrives with nested cells.

## How Does the Double-Layer Fan Work on a Circle?

Fan folding’s purest radial form; every slice carries a double pocket.

On round glass the double-layer honeycomb opens from the centre point toward the rim — like a wheel spoke. In each radial slice two nested cells come stacked; a double pocket forms over the whole circular plane.

The panel can stay as a fixed fan or gather at the centre; in the open state the circle’s line shows fully. Even on a fixed fan the double cell keeps working on the glass line.

On the circular glass of churches, villas and classic façades the cover follows the geometry; a square cut breaks the glass’s shape while the radial fan completes it.

## Standout Parts of the System

Radial fan, rim rail and double-layer panel are the system’s identity.

- Radial Fan The double-layer honeycomb opens like a wheel from centre to rim.
- Circular Double Pocket In each radial slice the nested cells come stacked; the double buffer stays while the fan is closed.
- Geometry Preserved The panel highlights the circle’s outline instead of cutting it.
- Diameter-Specific Every circle is produced to its measured diameter and depth.

## Who Is the Round Duette For?

Places wanting insulation along with the cover on a circular window.

On a rose or rose-window glass the radial fan completes the circle; a straight blind leaves gaps at the diagonal corners. On wide circles along the façade line the double cell raises an extra buffer.

On bathroom and stairwell circular glass the privacy fan opens; the soft light filtered through two layers diffuses inside.

On a large-diameter circle motorised gathering is chosen; on a small circle a fixed fan suffices. For the thin single-cell alternative the [round honeycomb blind](https://www.fenetresystems.com/en/round-honeycomb-blind/) is described on a separate page.

## Frequently Asked

Does the round duette open?

A centre-gathering variant is offered; most circles also take a fixed fan.

Is the diameter enough?

The diameter and the frame depth are recorded; production then works off the circle template.

Does it cut light?

Light filtering through two layers diffuses softly; the cut deepens with blackout fabric.

Does it fit a semicircle?

Semicircle and transom glazing take the same radial arrangement.

The glasses where circle forms are applied are shown in the [special window group](https://www.fenetresystems.com/en/duette-blinds-for-geometric-sloped-windows/); the oval counterpart is given on the [oval system](https://www.fenetresystems.com/en/oval-duette-blind/).
