Introduced for the first time by Jansen at BAU 2013, the Janisol HI system sets new standards in thermal insulation. Triple glazing doors achieve an excellent coefficient of thermal transmittance of UD 1.0 W/m2K. Thanks to the high-tech insulating bars made from glass fibre-reinforced polyurethane, the new door system achieves excellent static values and its performance has been highly confirmed in numerous tests (air/water/wind/mechanics). Delivery starting on 01 July 2013.
