Our windows and doors are made from professional, certified steel profiles

Fire doors and fire-resistant partitions of class E30/EW30/E60/EW60 can be easily assembled using the tried-and-tested Economy profiles. It is even possible to achieve fire resistance classes up to E120 for partition walls. The profiles with a depth of 50 have very narrow face widths. The appearance is identical to that of the other fire protection systems Economy 60, Janisol 2 and Janisol C4.

Slim steel profile system for interior doors and walls

The extremely reduced face width of Jansen Art’15, the new non-insulated steel profile system from Jansen, allows a unique design, while the steel material ensures a long service life. In this way, Jansen Art’15 not only meets the high design demands of ambitious architects, but also the high expectations of discerning clients in terms of design and function. Jansen Art’15 doors and partitions separate the entrance hall from the living space, the kitchen from the dining area, or the home office from the living room, without compromising on the generous space. The extremely narrow, highly resilient steel profile system always ensures durable, highly stable constructions in an unparalleled slimline frame.

The 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.

All of CORTIZO’s building systems are tested in the Testing Laboratory of our Technology Centre to guarantee the best performance of water tightness, air permeability and wind resistance, guaranteed by obtaining the maximum results in their test classifications.

Inspired by classic line designs,this new system allows to combine aluminium’s outstanding performance values with a steel appearance.
