# Sloped Duette Blind

Double-layer honeycomb on the sloped glass plane. A two-cell answer to the roof line’s heat loss.

## How Does the Double Layer Work on a Slope?

The rail beats gravity’s angle; nested cells follow the plane.

On sloped glass the panel cannot work vertically; gravity would hang it off the plane. Side rails hold the double-layer honeycomb to the angular plane — the system slides along the slope.

A roof slope takes the sun square and the winter head-on; it is the space’s fastest heat-losing face. Two nested cells raise a double buffer on the glass plane in this harsh condition.

The panel inside the rail holds position on the slope; tension cords prevent sagging, and whatever the angle the double pocket stays flush to the plane.

## Standout Parts of the System

Slope rail, tensioning and double-layer panel are the system’s identity.

- Rail Grip On the sloped plane the double-layer panel grips the side rails; no sagging.
- Sloped Sun Break Heat striking square to the roof slope is met by two nested cells at the glass plane.
- Double Pocket on the Slope Even on the sloped line two honeycomb layers stay stacked; the buffer follows the plane.
- Angle-Specific Slope angle and size measured to produce.

## Who Is the Sloped Duette For?

Places wanting both cover and heat break on sloped glass.

On the attic’s sloped window the sloped duette unites cover and insulation on one plane; a vertical blind sags while the double layer stays in the cavity.

On the stairwell’s sloped glass the railed panel follows the angle; the nested cells hold on this line the heat escaping the upper floor.

On fully vertical windows the sloped system is unnecessary; on sloped glass where the single cell suffices, the [sloped honeycomb blind](https://www.fenetresystems.com/en/sloped-honeycomb-blind/) is described on a separate page.

## Frequently Asked

Does the sloped duette panel sag?

Side rails and tension cords hold the plane; whatever the slope angle, there is no sagging.

How is the angle measured?

The slope degree and glass size are measured; the rail angle goes into production.

Why does the double cell matter on roof glass?

The sloped glass line is the space’s fastest heat-losing face; two nested cells raise a double buffer on this plane.

Does it stay fully open?

Inside the rail the panel holds at any position; partial coverage is possible too.

This page is the system’s mechanism, configuration and mounting; the duette-or-honeycomb decision on a sloped window is compared in the [application decision guide](https://www.fenetresystems.com/en/sloped-window-duette-blind/). The attic scenarios where the slope rail works are detailed in the [attic application](https://www.fenetresystems.com/en/attic-duette-blind/); the fully horizontal plane is solved on the [ceiling system](https://www.fenetresystems.com/en/ceiling-duette-blind/).
