IMPEX® – when material becomes light!

On August 21–22, 2026, the @Électrolapse Festival transformed Saint-Sorlin-en-Valloire into an impressive setting for music, light and immersive stage design.

At the heart of the festival, the Main Stage featured a striking central structure with luminous, crystal-inspired elements and backlit panels made from IMPEX® J850 Opal 3 mm.

For a stage design of this scale, the material needed to combine visual impact with technical performance and design flexibility. IMPEX® polycarbonate sheets offer excellent impact resistance, outstanding optical properties and versatile fabrication possibilities, complemented by very good fire performance of Euroclass B-s2,d0 according to EN 13501-1 – qualities that make them particularly well suited for creative applications in exhibition and stage design.

In this project, the opal surface of IMPEX® J850 helped create the illuminated elements of the scenography, interacting with backlighting and laser projections to bring the crystal-inspired design to life.

The result: an impressive interplay of material, light and creative design that became an integral part of the festival experience.

Our thanks go to Jean-Christophe Bossio, architect and author of the Electrolapse scenography, for his creative vision, and to everyone involved in bringing this impressive project to life.
