Professional aluminium cladding systems
Gemini Linear
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.

Design & functionality
System corners joined at 45º.
Corner joints with „invisible weld” technology to guarantee a smooth, uniform surface.
Mechanical jointing of corners using fasteners with visible cut edges.
Easy and quick installation in production conditions.
Optional bending of sash and frame profiles to create structures with unusual shapes.
Proprietary software for preparing quotes and placing orders.
A solution compatible with Classic and Soft Line aluminium window sills.
An option for using the Gemini Insecta system frame mosquito net.
An option to install a Gemini IGB balustrade integrated into the cladding or an independent balustrade with Gemini VGB extended profile.
Glazing from the outside with aluminium strip. Outside glazing solution is based on frame profile, to which we connect aluminium glazing bar, supported by our system gasket.
