The Metal Construction Association (MCA) has made available the first of several releases of industry-standard guide specifications. The first release consists of two specifications, based on criteria applicable to insulated metal panels (IMPs) captured within the International Building Code® (IBC). The specifications, prepared by the IMP Alliance of MCA, are intended to assist designers in construction of project specifications of the IBC 2018 version.

IMPs are lightweight composite exterior wall and roof panels with metal skins and an insulating foam core. These panels have superior insulating properties, and their outstanding spanning capabilities and one-pass installation makes them quick to install, saving costs compared to other wall assemblies. Like all building materials, IMPs must meet the provisions of the building code in effect for the project and site under consideration. However, certain basic parameters listed in this specification are generally required for use on most commercial buildings in the United States. Going forward, they will be used as base documents for MCA’s educational efforts.

The package has two separate downloadable specifications, one for roofs and the other for walls. Each includes the design and performance requirements, as well as sections on approved manufacturers and the delivery, storage, and handling of the materials.

MCA brings together a diverse industry for the purpose of expanding the use of metal in construction through marketing, research, technology, and education. Companies involved in MCA gain tremendous benefit from association activities that focus on research, codes and standards, market development, and technical programs. MCA’s market development efforts increase the use of metal materials in construction through the education of the building and design communities about the benefits of metal.
