From brief to installation
A complete workshop approach.
We define the geometry, membrane and inflation principle. Our Paris workshop patterns, welds, tests and prepares the complete installation.
Choose the surface for the visual role
A transparent sphere reveals its contents. A printed sphere carries graphics; a glossy finish emphasises colour and reflections. Illuminated and projection spheres have distinct lighting briefs. Start with the intended effect before choosing a size or finish.
Opaque and matt finishes
Opaque or matt finishes and compositions in several diameters can be studied within the same sphere range. Describe the colour, surface effect and arrangement you need.
Choose the diameter with the setting
The French sphere range gives an indicative span of 0.5 to 10 m across different finishes and constructions. This is not a standard size range for every variant. The intended effect, available space, access, mounting and inflation arrangement determine the feasible diameter.
