Jansen A.G. (Switzerland), founded in 1923, is a leader in the production of profiles for steel facades, doors and windows. The advantage of steel profiles in relation to aluminum is in its elegant design (thinner profiles), higher payload capacity, no limitations in dimensions, etc. Architects have noticed these advantages and enthusiastically apply Jansen systems in their projects.

Steel facade, door and window systems began to be widely used when thermally insulated profiles were produced. Today, Jansen offers elegant, thermally insulated profiles that can also be used in passive houses.

Mass Ltd creates real masterpieces on buildings across Europe with Jansen’s profiles.
