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.

Horizontal Duette Blind

Duo panel sliding on a side rail

Sliding door and wide façade

Vertical Duette Blind

The classic up-and-down layout

Standard window

Ceiling Duette Blind

Horizontally tensioned ceiling panel

Skylight and winter garden

Cased Duette Blind

Closed system with side rails

Rooms where edge leakage is unwanted

Triangular Duette Blind

Fan-folding angular panel

Gable and triangular glass

Oval Duette Blind

Elliptical fan panel

Gable-top and oval glass

Between-Glass Duette Blind

Panel embedded inside the glazing

A unit that never gathers dust

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 page; the spaces each model works in are listed in the application areas.
