s: 203
The Subtle One
The s: 203 louvred window combines innovative and advanced engineering with architectural restraint. Each insulated glass pane is suspended directly within the fully insulated aluminum frame, reducing any visible components to an absolute minimum. The result is a system that sits flush and integrates seamlessly into both historic and contemporary roof surfaces, while enabling generous daylight openings.
All louvres can be opened and positioned steplessly, allowing for efficient natural ventilation and precise control of daylight. Concealed 24-volt drives support a wide range of operating modes, from simple wall switches to fully automated systems with rain, wind, and temperature sensors. Interior and exterior shading, insect screens, and integrated LED elements can be added discreetly.
Manufactured using high-quality materials, recycled PET, and an exceptionally energy-efficient construction, the s: 203 sets a clear benchmark for sustainability and climate-conscious architectural design.
