Duette Blinds for Geometric and Sloped Windows

Duette blinds on sloped, roof and triangular or trapezoid windows: the strongest heat cut and a form-following custom cut.

Geometric and Sloped Windows Pages

In non-standard geometry the duette’s return is twofold: the tensioned system keeps the fabric straight on the slope, the double air pocket builds the strongest brake on the roof plane taking the most heat. On the triangular and trapezoid the custom cut follows the form. The triangular window’s narrowest angle decides the cut tolerance; at the sharp corner the fabric edge is calculated so it does not separate from the rail.

Window Form

With the slope, edge count and angle information, the system type is decided.
