Security, tested and certificated


On an objective level, expectations around the issue of safety and security tend to be subject to national standards. However, as individuals, we all have our own ideas about what is and isn’t safe. People view safety as a basic need and tend to seek out refuge and a sense of security in the buildings, cities and spaces that surround them. There is a range of timeless solutions that have been used for generations to address objective requirements (such as protection from fire, burglary, gunfire or explosions), as well as more subjective needs (clarity, brightness, orientation, etc.). With its signature Swiss precision, Jansen meets the highest standards of safety and quality, while also making a distinctive architectural statement with its bold yet delicate design language.
