The Metal Construction Association (MCA) has released the first of several industry-standard guide specifications. The first release consists of two specifications, based on criteria applicable to IMPs captured within the International Building Code or IBC. The paper is designed to aid designers working with Insulated Metal Panels (IMP) to help them meet the provisions of the National Building Code of Canada (NBC) 2015 edition as well as project specifications, notes and other contract documents.
An IMP is a roof or wall cladding element consisting of two metal skins surrounding an insulating core. IMP is designed to provide a weather-resistant, vapor retarding thermal barrier suitable for use in commercial construction. The package includes two sections, one for IMP walls, and another for roofs, each with sections that detail design requirements, performance requirements, approved manufacturers, installation, and more. Going forward, they will be used as base documents for MCA’s educational efforts as well.
“These documents are further representation of MCA’s strong commitment to safety standards in the metal construction industry. These papers are an excellent resource for designers in Canada and throughout the United States,” says Andy Williams, MCA’s director of codes and standards. “If you’re working with IMP, you should absolutely read this.”
