Jansen Arte
Slim steel windows and doors — Janisol Arte 2.0 — for renovation, protected structures, and elevations where a steel sightline is the point.
Why we carry steel alongside Sky-Frame.
Sky-Frame is the right answer for a large frameless opening. It is the wrong answer for a sash replacement in a protected structure, or a run of narrow steel windows in a renovation. Those need a profile you can see, made slim enough to read as steel rather than as a frame.
Janisol Arte 2.0 is Jansen's second-generation slim steel system. It comes in strip galvanised steel, stainless steel or Corten, and suits both the renovation of old windows and new residential work.

For architects
Steel or Sky-Frame?
If you're not sure which an opening needs, send the drawing. Often the answer is both, on different elevations.
