More about this product

Janisol HI windows are the very first steel window in Switzerland with Minergie certification: slender frame moldings enhance the architectural styling while the innovative technology ensures the best possible thermal break.

With triple glazing, it is easy to achieve windows with excellent thermal conductivity coefficients (Uw), e.g. 0.69 W/m2K for fixed lights and 0.8 W/m2K for opening elements. Thanks to high-tech thermal break spacer bars made of glass-fiber reinforced plastic, the new window system also benefits from excellent structural values and achieves top values in system tests (air/water/wind).
