Fire protection systems

Protection of human lives and material goods from destructive flames.

We integrate fire protection systems into the overall design of the building.


The basis for thermally insulated fire protection constructions is a completely insulated facade system for facades. By selecting the appropriate components and filling elements, the desired fire resistance class is achieved.

JANSEN fire protection systems enable different requirements to be met while maintaining a harmonious appearance – even fire doors can be integrated without changing the appearance of the building.

Fire protection in buildings aims to minimize the effects and prevent the spread of fire.

To assess the fire load, the materials were divided into building material classes (flammable / non-flammable) according to their behavior in fire.

The fire resistance class shows how long a building component or fire barrier reliably prevents the spread of fire. Building material classes and fire resistance classes therefore cover a wide range of different situations.

When it comes to behavior during a fire, the question is whether the material burns or not – and if it burns, whether it is easily or hardly flammable. Fire resistance is the ability of a component to safely withstand a flame for a certain amount of time.

Steel is perfect for the production of fire and smoke barriers.

What began in 1923 as Josef Jansen’s craft workshop in Oberriet developed into a high-tech company operating in the international market. In doing so, typical Jansen values have been retained. The pioneering spirit of that time is also reflected in today’s products and services.

Today, Jansen AG manufactures and sells welded and drawn precision steel pipes as well as steel and stainless-steel profile systems for windows, doors and facades, and pvc products for construction, as well as industry: products that guarantee Swiss quality, innovation, longevity and energy sustainability. To this day, the Jansen Group has remained in 100% family ownership and employs about 1,000 associates internationally, of which approx. 60 studies the craft.

This Swiss family business generated a turnover of 285 million francs in 2013. Around the world, Jansen is active through representative offices and partner companies.

The production facilities in Oberriet and Dingestädt (D) process 300 t of raw materials per day, which roughly corresponds to the weight of an Airbus A 380. That is, if all the pipes, which Jansen produces annually, were connected, the earth’s equator could be encircled twice.
