Solar Façades & Cladding
Active Building Assets for High-Performance Architecture
Discover SolutionsWhy Activate the Façade?
In modern urban architecture, the roof alone is often insufficient to achieve Zero-Emission Building (ZEB) standards. The façade offers a vast, untapped surface area for energy generation.
ISSOL® transforms this potential into reality. We replace passive cladding materials—stone, metal, or composite—with active BIPV glass elements. The result is a building envelope that pays for itself, reduces carbon footprint, and adheres to the highest aesthetic standards.
- Design Freedom: Custom colors, prints, and textures.
- Performance: Up to 180 Wp/m² seamlessly integrated.
- True Replacement: Offset costs of traditional materials.
Façade Applications
From opaque cladding to transparent skins, our systems adapt to your architectural intent.
Opaque Cladding
For blind walls, parapets, and ventilated façades. ISSOL® Noctis, White, and Chroma replace traditional siding with robust, energy-generating glass panels certified for impact resistance (EN 12600).
Curtain Wall Spandrels
Seamlessly integrate active energy into the opaque zones of curtain walls. Our modules fit standard framing systems, maintaining the visual rhythm of the glass façade.
Second-Skin Façades
Use semi-transparent ISSOL® Square or Stripe modules to create a double-skin façade. This provides solar shading, privacy, and energy generation in one architectural layer.
