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.

12.1E. Profile "Reveal" Panels (Isometric)
The overall Profiled Panel engagement system is very adaptable, providing an excellent template for architectural expression and a popular option for rainscreen use. This variation creates a visual reveal at each panel edge, with a planar surface for the main panel area. Thicker copper panel material provides for a flatter surface on wider panels. CDA has tested a 20” wide format version of this system in 32oz thick copper to the challenging American Architectural Manufacturer’s Association (AAMA) 509 testing protocol “Voluntary Test and Classification Method for Drained and Back Ventilated Rain Screen Wall Cladding Systems”.

12.1F. Typical Splice Plate with Isometric View
Splice plates diverts water from within vertical revels. Adjacent splice plates are installed prior to panels. The plates are held in place by edges of main wall panels, a loose lock engagement hem along their lower edge and fastener at the top.
