s: 305

The Filigree

The s: 305 louvre window is a proprietary, patented glazing solution that combines architecturural clarity with functionality and durability. Its filigree design gives the system a light, elegant appearance, while the stainless-steel structure, reduced to the essentials, integrates naturally into a wide range of architectural and interior styles.
The s: 305 glass louvres are highly versatile in application, whether used as a façade solution, courtyard glazing, roof glazing, glass roof, daylight band or glass pyramid. Wherever daylight, transparency and natural ventilation are required, the system demonstrates its strengths. Through its integrated ventilation function, complex and cost-intensive mechanical ventilation systems can often be reduced or, in many cases, avoided entirely. This is a particularly valuable advantage in public and highly frequented buildings.
Proven in daily use and realised in hundreds of projects, the s: 305 louvre window represents Swiss engineering expertise, high functional performance and long-term durability.
