Chicago, IL – The Metal Construction Association (MCA) has published two new Specification Guides for Metal Composite Material (MCM) systems: one for 4mm MCM systems and one for 6mm/8mm MCM systems. Both documents are available for download at no cost on the MCA website at

The new MCA MCM Specifications Guides specifically define performance criteria for MCM panels, installation systems, and system fabricators in a single document. In addition, the specifications define performance criteria for the MCM systems based on the latest International Building Codes (IBC) and performance standards developed by the American Society for Testing and Materials (ASTM) and American Architectural Manufacturers Association (AAMA).  The specifications also provide specific installation criteria giving direction to the installer and assurances to the designer regarding the quality of the installation.

“MCA is proud to offer these guides to assist fabricators, designers and installers by providing detailed guidelines and the most up-to-date specifications for MCM systems in one convenient document,” says Scott Kriner, MCA’s Technical Director.

Metal Composite Material (MCM) is defined as two sheets of aluminum sandwiching a solid core of extruded thermoplastic or a liquid plastic core injected in a continuous process with no glues or liquid adhesives between dissimilar materials. The core material shall be free of voids and/or air spaces and not contain foamed insulation material. The MCM systems include MCM, joints, attachment system components and miscellaneous materials as appropriate for the design of the project to provide a weather-resistant exterior cladding system.
