# Duette Blind Systems

A cell-within-cell architecture — a two-stage thermal barrier and full blackout with double-layer honeycomb fabric.

## Double-Layer Components

The double-layer fabric is the centre of the system — the mechanism and rail are balanced to carry it.

### Double-Layer Fabric

A cell-within-cell architecture — two honeycomb layers are woven back to back. Air is trapped on two separate floors.

### Blackout Compatibility

Blackout fabric + double cell cuts both light and the thermal bridge — the highest-performance structure at night.

### Lift Mechanism

Chain, cord and TD/BU options plus motorised drive — carrying balanced for the double-layer weight.

### Two-Way Folding

The upper half folds while the lower stays fixed, or two ends meet in the middle — on sloped and ceiling glazing.

## Folding Modes

Four working styles of the double layer — chosen by glass position and night-time need.

Operation and use of duette blind folding modes
Mode — Operation — Ideal Use
Bottom-Up/Top-Down — Bottom and top bars move freely — Standard windows, partial opening
Fixed Bottom — The upper layer folds — the bottom stays fixed — Sloped roof glazing
From Two Ends — Folds from both ends and stops in the middle — Winter-garden ceilings
Fully Closed — The double layer opens fully — Night darkening, maximum insulation

## Where the Double Layer Is Strongest

Three examples where the double layer makes the difference.

### Bedroom

Double cell + blackout = full darkness and a barrier holding the night warmth inside.

### Winter Garden

On wide glass surfaces the double layer balances both summer heat and winter loss.

### Roof and Sloped Glass

Guided folding on horizontal and angled surfaces — the fabric keeps its position.

## Duette System Variants

The same duo section, nine different working layouts — the geometry of the opening chooses the variant.

## Questions About the Duette Blind System

What does the double layer of a duette blind add?

Two honeycomb layers working back to back split the air pocket in two — the thermal bridge travels a longer path than on a single layer. Darkening comes out cleaner and the fabric surface sits fuller.

Is the highest blackout result achieved with a duette?

Blackout fabric + double cell is the strongest darkening combination among mechanical blinds — side-guided mounting is recommended to reduce edge leakage.

What is its effect on heat?

The double-layer air pocket forms a two-stage barrier between the glass and the room. The industry speaks of heat-loss reduction in the 25–40% band — we do not promise an exact figure, we present it as a contribution.

Should motorised operation be preferred?

Double-layer fabric is heavier than a single layer — on wide sizes or hard-to-reach glazing, motorised operation is recommended both for comfort and for mechanism life.

How the connection options are applied to the double-layer system is explained on the [Duette Blind Installation Types](https://www.fenetresystems.com/en/duette-blind-installation-types/) page; the spaces each model works in are listed in the [application areas](https://www.fenetresystems.com/en/duette-blind-application-areas/).
