Study nature, love nature, stay close to nature and it will never fail you.

Light should inspire you, and what’s more, vitalise you.

Clara rethinks

window design

Architects and builders wish to have modern windows that are large and transparent. They should let as much natural light into the room as possible, minimise heat loss in winter, be soundproofed and, extending beyond that, make life very difficult for burglars. Thanks to the evolution in window technology, thermal insulation, energy efficiency and sound insulation have long become standard features. Frost patterns and draughty windows are now fortunately a thing of the past. So far so good? That’s not good enough for us yet, so we deconstructed and re-designed the window at Clara.

Evolution is followed

by the revolution

How does every window become a panoramic window? How do we replace frames, mullions and sash bars that break up the view outside and reduce the incidence of light? How do we still manage to create a sturdy, airtight window with excellent rigidity? The answer was as sophisticated as it was simple, and an absolute innovation: Clara is the world’s first frameless window with a casement made entirely of glass. The filigree, simple design perfectly complements contemporary architecture, fills rooms with more natural light and offers almost unlimited freedom of design. Clara, the window with a view. Made in Switzerland.
