Description: Beveled copper panels typically have a significant depth for bold heavy-shadowed effects. In order to provide the rigidity required, the minimum recommended thickness for copper is 20 ounce half-hard temper alloy.
Panels are typically limited to 10 foot lengths. Transverse seams are 6", minimum, lap joints. The joints must be staggered on successive runs to reduce the build-up of multiple layers of copper at one point, which would make it difficult to fold the horizontal joints. This is particularly important since beveled panels use fairly rigid copper material.
Note: Panel profile, thickness and lengths must be reviewed per structural considerations.
Substrate: Continuous nailable substrate.
Fastening Method: Cleats screwed to substrate.
12.3A. Typical Section
A single lock seam is used in the horizontal joint between runs. Cleats, spaced at 16" on center, are used to fasten the panels to the substrate.

12.3B. Typical Axonometric
This detail shows an overall view of a beveled panel wall system. The deep panels provide strong horizontal shadow lines. The transverse seams should be staggered, as shown.

12.3C. Inside Corner
Copper flashing is laid over wood blocking in the corner to close the gaps at the ends of the panels. The flashing extends a minimum of 4" under the panels, and is held by cleats at 12" on center.

12.3D. Outside Corner
The ends of the panels in this condition are closed by copper flashing. The flashing extends a minimum of 4" under the siding and a minimum of 1" over it. Wood blocking and trim is used to finish the corner. An alternate detail is shown in Detail D in Wall Cladding - Profiled Panels.
