12.8. Copper Clad Honeycomb Systems

Description: Copper clad honeycomb panels are engineered and fabricated by a variety of manufacturers. They are light weight, strong, and offer a very flat copper panel appearance. Total panel thickness is variable to suit project requirements.

The honeycomb material varies depending on manufacturer and whether it is an interior or exterior application. Copper is bonded to the front side of the honeycomb and a backer panel is bonded to the back side. The backer panel is required, to ensure the rigidity of the assembly, thereby minimizing warping. The backer panel is usually of a material compatible with the structural system.

The details shown are generic, and do not represent a particular system. The details illustrate a system attached to a steel structure. With proper detailing, copper clad honeycomb panels can be installed on virtually any kind of structure or wall. For information on specific systems, contact the manufacturer.

Substrate: Any substrate or structure as required by the specific system manufacturer.

Fastening Method: Typically screws or bolts, as required by the specific system manufacturer.

12.8B. Horizontal Joint Section

These panels are shaped to provide hidden surfaces for the compressible gaskets. The joint shape is designed to prevent water penetration.

Separation of dissimilar metals is an important consideration in the design of copper clad honeycomb panels. Manufacturers have engineered a variety of solutions, depending on the honeycomb and backer panel material, and the method of attachment to the structure.

In the system shown, the backer panel is not copper. Separation is maintained between the copper cladding and the backer panel. Steel or aluminum support angle brackets are bolted to the backer panel. The support brackets are bolted to continuous support angles which are welded or bolted to the steel structure. Shims or other leveling devices may be required for proper panel alignment.

12.8C. Vertical Joint Section

The vertical joint is detailed the same as the horizontal joint, with an additional compressible gasket to reduce water penetration.
