Mullion and transom facade
VELLA
Vella is a wood-aluminium system designed for the construction of facades and winter gardens. The system consists of a wide variety of aluminium profiles, seals and insulators. It ensures permanent fixing of the glass, extraordinary tightness, high thermal parameters and guarantees excellent protection for wood.

The load-bearing structure is made of wooden mullions with a thickness of 50, 60 or 80 mm and a depth adopted based on static calculations.

Design & functionality
Complete gutter system.
Profile bending is possible in the case of transom 50.
High tightness thanks to the use of coat seals.
Compatible with Gemini window and door systems: Classic, Linear, Quadrat, Quadrat FB, Integral I and II.
Possibility of using glazing units of different thickness inside one mullion/transom thanks to the use of levelling profiles.
Various cap profiles, including with wooden cladding
Up to 3 levels of drainage possible.
Wide range of available installation variants
Vella S system available with structural glazing technology
Vella S - three ways of fixing the glass: holding by the inner pane, by the glued-in frame or pointing by the glued-in fasteners.
