Janisol Primo

With only 60 mm installation depth, the thermally broken steel profiles achieve excellent thermal insulation values and make an active contribution to environmentally compatible sustainable building. The assembly and manufacture of Janisol Primo and combination with Janisol systems are simplified by the use of identical profile cross sections.

Janisol Arte 66

With Janisol Arte 66, Jansen is expanding its range of systems to include an attractive variation. The basic depth of 66 mm enables the use of stronger glass, with a vent height of up to 2300 mm. This makes it possible to have the turn/tilt opening type, even with the special requirements of listed buildings for narrow frames. With the concealed fittings, they meet architects’ and developers’ demands for a uniform design and clear lines which do not allow any visual interruption. The Euro grooves make it easier for fabricators to install the fittings, while the new glazing bead system facilitates installation of the panes. Fabrication with push-in gasket or dry glazing takes place in the usual way, as with the Janisol and Janisol Arte 2.0 steel profiles – this ensures a high level of process reliability.

Janisol Window

The slender profile face widths of Janisol windows provide the space for creativity and lend the building a quite special character. Whether it is sash bar variants, arched windows or large-glazed elements: the Janisol window system is particularly suitable for use in new buildings as well as for the refurbishment of existing buildings.

Janisol HI Window

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).

Economy 50 Window

With an installation depth of only 50 mm, the Jansen Economy 50 profile system is suitable for slender, elegant window designs without thermal insulation. Tested systemised fittings and fixtures are available for all common opening types.

Janisol Art

This profile series was specially developed for the refurbishment of industrial and loft glazing as well as heritage windows. Typically finely proportioned windows in the Bauhaus style can be almost perfectly reconstructed with the extremely ultra-slimline, thermally broken profiles. Slim profiles aesthetically with the same appearence as Janisol Arte not thermally broken.


Art System is a combination of the Economy window and Art 15 series, achieving a fantastic serie of windows. Profiles without thermal break with exceptional aesthetics, having the most slender profiles on the market.
