Gemini Linear is a system where the sash surface is flushed with the frame. However, unlike other flushed systems, such as Quadrat FB, the GEMINI Linear creates a clear angle on the surface. Just like other GEMINI systems, it is characterised by above-average functionality and utility. Gemini Linear is suitable for flushed and modern designs that blend in well with the concept of the building. Application: windows, doors, facade elements and winter gardens.
