# Triangular & Trapezoid Window Venetian Blind

Venetian blind on the triangular and the trapezoid window: the slat limit on the slanted edge, a custom-production condition.

## Triangular & Trapezoid Window Analysis

On the triangular and the trapezoid glass the venetian is limited: the horizontal slats leave a gap on the slanted edge or break the form — the standard system does not fit this geometry. Custom-production and fixed-cut variants work within a narrow measure; letting the slanted edge stay free or [having the cellular fabric follow the form](https://www.fenetresystems.com/en/triangular-duette-blind/) gives a righter result in most projects. The suitability is evaluated per the window form.

### Slanted Edge

The horizontal slat does not overlap the slanted edge; a form gap or a cut problem arises.

### Limited Variant

The custom-production and fixed-cut variant works within a narrow measure.

### Alternative

Leaving the slanted edge free or having the cellular fabric follow the form is right in most projects.

### Evaluation

The window form decides the suitability; the standard system does not fit.

## The Slats’ Reality on the Slanted Edge

The triangular and the trapezoid glass is an architectural form; the horizontal slats do not overlap the slanted edge. The standard venetian does not fit this geometry — the limit is clear.

Custom-production and fixed-cut variants work within a narrow measure, but in most projects leaving the slanted edge free or having the cellular fabric follow the form gives a righter result.

The suitability is evaluated with the window form; the slope angle and the edge length give the decision.
