MCA conducts many technical studies and research projects in partnership with member and industry partners. These studies include bulletins, white papers, manuals and reports that ensure that metal is at the forefront of innovation, and proactive with codes and standards.
Metal Composite Material (MCM) has been used as a means of exterior cladding in North American construction for more than 40 years. In order for this flat sheet material to be used, it must first be fabricated into an assembly that is installable on the structure. These different assemblies are known as installation “systems”. In this Technical Bulletin, we will define the basic installation “systems” that were first developed, and continue to be used today. We will also discuss some of the more sophisticated designs that are currently popular and meet the performance requirements of building technology practiced today. When finished with this paper, the reader should have a basic understanding of the different system types and the performance characteristics that make each type of system unique.
Metal Composite Material (MCM) suppliers, fabricators, and installers must provide assurances that both the MCM and MCM assemblies will meet the requirements defined in the applicable building code. Typically, these requirements are defined in the code through reference to established testing in the areas of structural, fire, energy, and environmental (air and water penetration) performance. The primary question is how can a designer be assured that the MCM supplied to the project meet these performance requirements?
The new 4mm MCA MCM Master Specification specifically defines performance criteria for the MCM panels, the installation systems, and the system fabricators in a single document while defining performance criteria for the MCM systems based on the latest IBC and AAMA performance standards. The Specification also provides specific installation criteria giving direction to the installer and assurances to the designer regarding the quality of the installation.
The new 6mm MCA MCM Master Specification specifically defines performance criteria for the MCM panels, the installation systems, and the system fabricators in a single document while defining performance criteria for the MCM systems based on the latest IBC and AAMA performance standards. The Specification also provides specific installation criteria giving direction to the installer and assurances to the designer regarding the quality of the installation.
Metal Composite Material (MCM) cladding systems are an attractive and popular way for architects to present their latest masterpiece. Clean, colorful and tough enough to protect everything inside, from everything outside, MCM is the “cladding of choice” for many of the world’s most beautiful buildings. It is not surprising then, that it takes a team of specialists to produce a high quality finished product.
With increased demands in energy conservation, designers are often looking for ways to include additional insulation on the exterior side of the wall assembly, behind the cladding, to meet the requirements of the code. Installation of this “continuous insulation” generally occurs in the free air cavity between the weather barrier and the exterior cladding material.
Recent global fire events have heightened the awareness regarding the use of metal composite material (MCM). Safeguards in place in North America help to ensure these types of fire incidents do not take place. By adhering to the performance criteria defined in the International Building Code (IBC) in the United States, the National Building Code (NBC), and the Provincial Building Codes in Canada and working with the experienced MCM Manufacturers and Certified Fabricators, MCM can be used safely and effectively on a variety of construction types.
Though building and fire codes primarily address structural and fire performance of MCM cladding materials, other performance indicators often are used in the construction industry to define an acceptable application. This document defines the unified position of the Metal Construction Association (MCA) and its members with regards to visual acceptance parameters.
The use of metal composite material (MCM) as an exterior cladding on high rise buildings is common throughout the world. There are many positive aspects of MCM, however recently, a number of dramatic fires reported around the globe have heightened concern regarding the use of MCM for exterior applications. The intent of this white paper is to provide information about MCM and MCM systems and the controlling factors in North America to ensure these types of fire incidents do not take place.
Metal composite material manufacturers typically provide two types of core products: standard and fire retardant. The Metal Construction Association’s MCM Fabricator Council has developed this paper to clarify the allowable uses for standard and fire retardant MCM in accordance with the 2006-2012 editions of the International Building Code.
