Janisol HI Windows

Een sterk staaltje isolatie: met het stalen Janisol HI profielsysteem voor ramen verlegt Jansen de grenzen op het gebied van thermische isolatie.

Introduced for the first time by Jansen at BAU 2013, the Janisol HI system sets new standards in thermal insulation. Triple glazing windows achieve an excellent coefficient of thermal transmittance of up to Uw 0.69 W/m2K (for fixed lights) and up to Uw 0.8 W/m2K (for windows). Thanks to the high-tech insulating bars made from glass fibre-reinforced polyurethane, the new window system also achieves excellent static values and its performance has been highly confirmed in numerous tests (air/water/wind). Delivery starting on 01 July 2013.
