Janisol Arte 2.0 Steel Windows

What is Janisol Arte 2.0?

Short answer: A second-generation, thermally insulated steel window system with ultra-slim profiles designed for historic replacement and modern loft projects. Available in steel, stainless steel, and Corten.

  • Built for industrial/loft glazing aesthetics with modern performance.
  • Integrated weatherstrip groove speeds fabrication and improves consistency.
  • Wide selection of glazing beads and accessory options for design flexibility.

Why dealers choose it:

  • Authentic steel sightlines—no faux “steel-look” compromises.
  • Strong performance classes for air, water, and wind.
  • Broad material palette (steel/stainless/Corten) for design control

Key Takeaway: Arte 2.0 keeps the historic look while adding a modern thermal break and tested performance.
