NOCOBOND Copper Composite Panel

Copper composite panel is composed of upper-surface copper, back-surface copper and the non-combustible core layer respectively connected with the high molecular adhesive film. The structure is copper – core – copper, which saves a lot of copper material than using solid copper panel. By contacting with air, the copper surface will gradually change into old copper, then green patina with the decorative effect more gorgeous and elegant. The surface is smooth and easy to be processed, which is mainly used for the decoration of the exterior wall of the building.

The widely use of copper in architecture

The history of using copper in architecture dates back to 10000 years ago. As one of the nobal metal, copper has a better performance than other metal in physical. Some of the world's most distinguished modern architects have relied on copper. Examples include Frank Lloyd Wright, who specified copper materials in all of his building projects; Michael Graves, an AIA Gold Medalist who designed over 350 buildings worldwide; Renzo Piano, who designed pre-patinated clad copper for the NEMO-Metropolis Museum of Science in Amsterdam, etc.
