What is the technical lifespan of a climate ceiling / system?

For the technical lifespan of a metal climate ceiling, we distinguish the lifespan of the metal ceiling and the water-bearing climate system. In practice, the end of the technical lifespan (> 30 years) is almost never reached because a renovation or renovation is already taking place before that time, whereby the ceiling is also replaced. The lifespan of the climate system also depends on the materials used, the water quality and the system pressure. From our own experience, we know that with normal use, the climate system also lasts for at least 20 years. After all, we delivered the first projects with climate ceilings more than 20 years ago and are still functioning well.
