The tested door system Janisol HI meets the highest insulation standards and is convincing in terms of safety and durability even under extreme stress conditions - as is the case particularly in public buildings with a large public traffic. With triple insulating glass, the doors are easily accessible with excellent thermal transmittance values of Ud 1.0 W/m2K. Thanks to high-tech insulators of glass fiber reinforced polyurethane, the new door system also achieves excellent static values and scores top values in system tests (air/water/wind). With Janisol HI, Jansen sets new standards in terms of contemporary architecture combined with superior thermal insulation.
