s: 211

The Generous One

The s: 211 roof window embodies maximum transparency and generous dimensions. Its frameless outer glass pane and the inner pane, held only by a slim aluminum profile, reduce visible components to an absolute minimum. The result is a clear, elegant roof opening that enhances both historic and contemporary architecture. As a fully bespoke solution, the s: 211 enables impressive formats far beyond conventional standard sizes.
Its construction allows for seamless into the roof plane, while opening wide views to the outside. Whether designed as a large, fixed glazing or as a hinged sash, the s: 211 brings light and space into a carefully balanced relationship. Even the exterior shading remains discreet: the fully concealed shading box preserves the calm, elegant appearance of the roof. In this way, the s: 211 becomes a refined yet confident architectural element, which integrates naturally into the roof and enriching interiors with light, openness and presence.
