# Horizontal Duette Blind

Double-layer honeycomb sliding on the side axis. The double-buffered companion to the sliding opening’s biggest heat leak.

## How Does the Horizontal Double Layer Work?

Its fundamental difference from the vertical duette is travel direction.

In this arrangement the double-layer honeycomb folds left-right rather than up-down. The panel stays suspended in the side rails; pulled, both layers gather to one edge together.

It shares the sliding door’s logic: the panel slides toward the wall or fixed glass and the passage opens completely. Closed, the nested cells raise a double buffer over the entire glass surface.

Wide glass doors are the façade’s biggest heat leak; even in the horizontal arrangement the double-cell geometry does not break — a two-layered barrier remains along the glass.

## Standout Parts of the System

Side rail, double-layer panel and gathering cassette are the system’s identity.

- Side-Axis Travel The double-layer panel moves on the horizontal axis, not vertically; the passage stays free.
- Double Pocket on the Sliding Façade Closed on wide glass doors, the nested cells raise a double buffer over the huge glass surface.
- One-Hand Passage The panel is pushed open; the path to the door clears completely.
- Cased Gathering The panel stores in the side cassette, protected from impact and dust.
- Made to Measure Exact-measure production for wide sliding openings.

## Who Is the Horizontal Duette For?

Places wanting cover + insulation on sliding and wide façades.

On sliding balcony and garden doors a vertical panel wants swing room; the horizontal duette slides in the door’s own direction and asks no extra space — and closed, the double cell wraps the glass’s weakest point.

On a wide glass façade the panel splits in two or gathers on one side; on twin rails two panels can meet in the middle.

For the lightweight single-cell alternative the [horizontal honeycomb blind](https://www.fenetresystems.com/en/horizontal-honeycomb-blind/) is described on a separate page; on a vertically opening window the standard vertical arrangement is preferred.

## Frequently Asked

Does the horizontal duette panel block passage?

The gathered panel stays a slim bundle on one edge; the passage clears almost completely.

What does the double cell add on a sliding door?

The balcony and garden door is the façade’s biggest glass surface; two nested cells raise a double buffer on that line and keep the glass’s winter chill outside.

Can it be double-panel?

Two panels slide opposite each other on two rails; a centre-meeting arrangement is built on wide façades.

Does it fit a glass balcony?

The rail arrangement adapts to the glass-balcony profile; rail measurements are stated on the order.

The window types where horizontal gathering is used are given in the [application pages](https://www.fenetresystems.com/en/duette-blind-application-areas/); its vertically opening sibling form works on the [vertical system](https://www.fenetresystems.com/en/vertical-duette-blind/).
