Janisol HI windows


Janisol HI windows combine aesthetics with refined technology. Slender frame profiles enhance the architectural styling while the innovative technology ensures the best possible thermal separation. 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-fibre reinforced plastic, the new window system also benefits from excellent structural values and achieves top values in system tests (air/water/wind). The Janisol HI window was the first steel window that has been certified according to Minergie.
