The Copper Development Association (CDA) recently released a study to simplify the specification process of copper wall cladding systems for architects, building owners, and contractors. The study, conducted by Intertek, provides quantifiable performance and technical data for common copper wall cladding systems, thereby eliminating the need for end users to conduct individual, costly, and time intensive tests to comply with the mandatory building code requirements.
The CDA tested several common systems in a variety of conditions according to ASTM/AAMA testing protocols, successfully obtaining ratings on air infiltration, water infiltration, wind resistance, and dynamic wind.
Formed copper panel systems have long proven durable and effective when applied to building exteriors, and design and construction teams continue to use them as a preferred material for roofing and increasingly wall cladding. The current round of testing focused on commonly used styles of standing-seam and flat-seam copper systems: horizontal and diagonal flat-lock panels, horizontal single-lock standing-seam panels, and vertical and horizontal double-lock standing-seam panels.
