12.1. Profiled Panels

Description: Profiled copper panels can have a variety of shapes and sizes. The shapes can be formed on site with a brake or powered forming equipment. They can also be pre-manufactured and specified with embossed patterns or other designs.

The minimum recommended weight for copper used on profiled panels is 16 ounces, but some panel profiles may require heavier material.

Note: Support blocking behind the panels may be required depending on panel thickness and dimensions, along with wall configuration, i.e., straight or curved.

Substrate: Continuous nailable substrate.

Fastening Method: Cleats screwed or nailed to substrate.

12.1A. Typical Section

This section shows a common seaming method used in the horizontal joint between runs. Cleats are used to fasten the panels to the substrate. The panel must not be shaped so that it holds water.

A minimum of two cleats per panel are required. The actual number and spacing needed should be determined by a structural engineer, to ensure wind and other loads will not lift or distort the panels. A minimum of two copper, brass, bronze, or stainless steel screws per cleat are required for fastening to the substrate.

12.1B. Typical Axonometric

This detail shows the single lock used at transverse seams. A lapped seam (6" minimum) may also be used. The transverse seams should be staggered as shown.

12.1C. Inside Corner

Wood blocking is used to fill the gap left between the copper panels at the corner. Copper flashing is installed over the blocking, and extends a minimum of 4" under the panels. The flashing is held by cleats at 12" on center.

12.1D. Outside Corner

The ends of the panels are closed by copper flashing over wood blocking. The blocking must be thick enough to completely close the end void. The flashing covers the blocking and extends under the panels a minimum of 4". The flashing is held by cleats at 12" on center.
