Triangular & Trapezoid Duette Blind
Duette blind on the triangular and trapezoid window: custom-cut double-layer fabric, strongest insulation and form fidelity.
Triangular & Trapezoid Window Analysis
The triangular and trapezoid glass is an architectural accent; the duette’s double layer fits the sloped edge with a custom cut — the strongest insulation and the softest filtering are given without distorting the form. On the trapezoid glass a moving bottom segment + a fixed sloped top section are planned together; on the triangle a fixed cut is also an economic solution.
Custom Cut
The double-layer fabric is cut per the window geometry; the sloped edge closes gap-free.
Double-Pocket Form
Even on the sloped edge two air pockets work; the strongest insulation is preserved on the special glass.
Segment Order
On the trapezoid the bottom flat section opens, the upper sloped section can stay fixed.
Architectural Fidelity
The triangular glass’s form is followed with the fabric; the blind does not cover the form, it follows it.
The Double Layer on the Sloped Edge
This page is for the space decision: is the duette suitable on a triangular or trapezoid glass? The fan-folding mechanism, the triangular rail and the configuration are detailed on the triangular duette system page.
The triangular and trapezoid window excludes the standard rectangular blind; the duette’s cellular fabric fits the sloped edge with a custom cut — the double air pocket gives the thickest insulation even on the special glass.
The movement is separated into segments: on the trapezoid the bottom flat section opens while the upper sloped section can be left fixed. On the triangle a single-piece fixed cut is also preferred.
The decision boundary is the look and the weight: the double layer’s cellular texture can sit thick on the small triangular glass; if a slim solution accentuating the form is wanted the single-cell honeycomb, if flat-fabric simplicity is wanted the pleated is compared.
The measurement is taken specially; the edge lengths and the angles enter the production plan directly.
Application Notes
Mounting & Selection for Triangular & Trapezoid Window
Cut
The fabric is cut per the template; the sloped edge follows the form.
Segment
A moving bottom + a fixed upper section are planned together.
Measurement
The edges and the angles are production data; the standard measurement is not sufficient.
Fixed
On the non-opening triangle the fixed panel is the economic solution.
