# Oval Duette Blind

Double-layer honeycomb fan on oval glass. The form-underlining cover arrives with nested cells.

## How Does the Double-Layer Fan Work on an Oval?

The elliptic cousin of the round fan; in the two-axis opening every slice carries a double pocket.

On oval glass the double-layer honeycomb raises elliptic slices opening from two focal points toward the edge — the elliptic counterpart of the circle’s radial fan. In every slice the nested cells come stacked.

While the fan is closed a double pocket forms over the whole elliptic area; along with the cover, two buffer layers remain on the glass line. The panel is fixed or gathering; gathered, the oval line frees itself.

On over-door transoms and classic oval windows the cover tracks the geometry; a rectangular blind would leave gaps at the oval’s edges while the elliptic fan wraps the form itself.

## Standout Parts of the System

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

- Elliptic Fan The double-layer honeycomb slices open from the oval’s focal points toward the edge.
- Two-Layered Slice In each elliptic slice the nested cells come stacked; double-pocket insulation keeps on while the fan is closed.
- Form Accent The panel highlights the ellipse instead of hiding it.
- Axis Measurement Long axis, short axis and depth are taken for every oval.

## Who Is the Oval Duette For?

Places wanting insulation along with the cover on an elliptic window.

On a transom’s oval glass the elliptic fan rests above the form; while covering the doorway’s architectural detail the double cell raises a buffer on the glass line.

On the oval windows of villas and historic buildings the cover is solved only with an elliptic fan; the double layer keeps working behind the glass even on a fixed fan.

On a small oval a fixed fan suffices; on wide ellipses the gathering version is chosen. For the thin single-cell alternative the [oval honeycomb blind](https://www.fenetresystems.com/en/oval-honeycomb-blind/) is described on a separate page.

## Frequently Asked

Does the oval duette gather?

A centre-gathering variant is offered; compact ovals often go with a fixed fan.

How is measuring done?

Both axes plus the depth are recorded; production then works off the ellipse template.

What does the double layer add on an oval?

On transom and façade ovals the nested cells raise two buffer layers; while the fan is closed the heat passage on the glass line slows versus a single layer.

Does a half oval work?

A half ellipse or an over-door transom takes the same fan arrangement.

The windows where oval and circular forms mount are gathered in the [special window group](https://www.fenetresystems.com/en/duette-blinds-for-geometric-sloped-windows/); the triangular cut is described on the [triangular system](https://www.fenetresystems.com/en/triangular-duette-blind/).
