# Between-Glass Duette Blind

Double-layer honeycomb panel inside the glazing unit. The system carrying insulation into the glass itself.

## How Does the Double Layer Work Between Glass?

The double-cell honeycomb panel embeds into the glass cavity; insulation moves inside the glass.

In the between-glass duette system the panel made of two nested pocket layers lives in the cavity between two glass sheets. From outside only the glass is seen; the panel travels in the inner cavity.

The glass cavity itself is an air buffer; the double-cell fabric arriving above it adds the second and third pockets. The insulated-glass + double-layer pair is the strongest passive section that can be produced on the glass line.

Control is done by magnetic slider or motor; it is managed from inside without drilling the glass surface. In the sealed cavity free of dust, moisture and contact the fabric stays new for years.

## Standout Parts of the System

Glazing unit, magnetic slider and double-layer panel are the system’s identity.

- Inside the Glass The double-layer honeycomb panel works in the cavity between two panes; no element on the outer surface.
- Triple Air Buffer Two nested cells are added above the glass cavity; a three-layered section forms on the façade line.
- Magnetic Control The slider on the glass surface moves the panel from inside; no hole is drilled in the unit.
- Glass-Unit Specific Produced panel-integrated at the double-glazing unit change.

## Who Is the Between-Glass Duette For?

The answer for spaces wanting insulation and hygiene together.

On north façades, wide shopfronts and glass surfaces where heat loss is felt, the double-layer difference is meaningful; the cells uniting with the glass cavity take the window line out of being the space’s weakest point.

In bedroom and study the soft light filtered through two layers cuts glare; in kitchens and bathrooms where hygiene is wanted the sealed cavity never soils the panel — wiping stays limited to the glass surface.

On joinery getting new glass or due a glass change, the unit is ordered with the panel; later addition is limited. For projects where the single cell suffices, the [between-glass honeycomb blind](https://www.fenetresystems.com/en/between-glass-honeycomb-blind/) is described on a separate page.

## Frequently Asked

Can it be retrofitted to existing glass?

A glazing-unit change is required; the panel arrives embedded in the insulated unit.

What does the double cell add between glass?

Two nested honeycomb layers add the second and third air pockets above the glass cavity; heat passage slows further than a single-cell panel.

How is the light passage?

Light filtered through two fabric layers enters the space soft and diffused; it leaves no sharp shadow line.

What if the panel fails?

The glazing unit is a service part; the unit is opened and the panel repaired or replaced.

The connection styles of the between-glass system are described on the [installation types](https://www.fenetresystems.com/en/duette-blind-installation-types/); fabric options are listed in the [product catalogue](https://www.fenetresystems.com/en/duette-blinds/).
