Janisol HI door


2022 02 Frame Png Webp

The tested and Minergie-certified Janisol HI door system fulfils maximum insulation requirements and, with respect to safety/security and durability, is also suitable for extreme service conditions – such as those in very busy public buildings. With triple glazing, it is easy to achieve doors with excellent thermal conductivity coefficients of UD 1.0 W/m2K. Thanks to high-tech thermal break spacer bars made of glass-fibre reinforced plastic, the new door system also benefits from excellent structural values and achieves top values in system tests (air/water/wind/mechanics). With Janisol HI, Jansen sets new benchmarks in terms of contemporary architecture combined with excellent thermal insulation.
