Description

This innovative system combines a high-performance window with a fully integrated shutter and sunshade, delivering comfort, efficiency, and modern design in one solution. Protected between two glass panes, the shutter and sunshade are shielded from weather, ensuring durability and smooth operation for years to come. The system can be operated either manually or with a convenient electric motor drive, while an additional glass pane further enhances thermal insulation and soundproofing. Available as a complete unit or as a retrofit option, the aluminum compound sash offers flexibility for both new construction and renovation projects. By improving indoor comfort, reducing energy use, and lowering CO₂ emissions, this system not only elevates your quality of living but also supports a more sustainable future.
