Gemini Quadrat FB

Gemini Quadrat FB systems have distinct profile edges, similar to the Quadrat system. The FB version is distinguished by its flushed sash which visually creates a unified surface.

Quadrat FB lacks a visible slant and there is a right angle on the surface of its profiles.

The special shape of the aluminium sash, which shifts the windowpane 15 mm further forward as in more conventional designs, allows for the use of broader glazing with a thinner wood cross-section. Much like other GEMINI systems, Quadrat FB stands out with high functionality and excellent utility properties. Application: windows, doors, facade elements and winter gardens.
