Lasting value, durable yet changeable.
After installation on the building, Copper Natur retains its typical bright red copper colouring for a period of time. Changes are very gradual and not entirely predictable - just like the weather, which, in turn, is solely responsible for copper's continual changes.
First, the surface turns matt. Gradually, the material develops an oxide layer to protect it against the effects of weathering. This process brings with it striking colour variations through an entire range of brown tones, offering varying nuances according to change of light and season.
Ultimately, on the sloping surfaces, the colour process yields a robust green patina - as is typical for copper surfaces. This patina lends the cladding its distinctive character, at the same time providing long lasting protection for decades to come.
