Copper  is highly resistant to harsh weather conditions, including rain, snow, and UV exposure. It provides excellent protection against the elements, making it suitable for various climates.

This siding does not require painting or staining. Over time, it develops a natural patina that enhances its appearance and acts as a protective layer. However, if desired, copper siding can be painted with special copper-compatible paints.

The patina development process can take several years, but it depends on environmental factors such as humidity and exposure to air. However, the process can be accelerated using patina solutions.

Copper is a naturally occurring metal that can be sustainably sourced through mining. Additionally, its long lifespan and recyclability contribute to its environmental sustainability.

While simple installations may be possible for DIY enthusiasts, it is generally recommended to hire professionals for copper installations, especially for complex projects. Professional expertise ensures proper installation and maximizes the longevity of the siding.

Copper Composite Material (CCM) is created by sandwiching two thin layers of copper around a fire-retardant (FR) core. It is also available as a custom order with a polyethylene (PE) core, subject to minimum quantity requirements. The genuine surface of copper will weather over time, developing a classic patina green based on the micro-environment of the project location. A green patina can also be achieved through a chemical treatment of the copper composite before installation, performed by a third party to the architect’s satisfaction.

The standard stock size is 38” x 196” (965mm x 4978mm) in 30-piece crates. Custom lengths and thicknesses are available. Please contact ALPOLIC® Customer Service for current available stock and additional information.

The finish color of natural metal cannot be controlled, so some variation should be expected.

The width tolerance is ± 0.08” (2mm), the length tolerance is ± 0.012” per ft (1mm/meter), and the thickness tolerance is 4mm ± 0.008” (0.2mm). The maximum bow allowed is 0.5% of the length and/or width, while the maximum squareness is 0.2” (5mm). The peel strength is greater than 22 in lb/in (ASTM D1781). ALPOLIC® material is trimmed and squared with cut edges to ensure the best sheet edge conditions in the industry.

Copper must be isolated from aluminum and other dissimilar metals to avoid galvanic corrosion. Panels should be stored flat in a dry, indoor environment. Protective film should be removed from panels soon after installation. Please refer to the CCM Fabrication Manual for routing and fabrication recommendations. Crating fees apply to orders for less than a standard piece crate.
