Anyone searching the internet can find dozens of products that lay claim to being MCM or Composite Materials. Solid extruded plastic core, wood core, corrugated metal core, honeycomb core, the term MCM has come to mean so many things that no one is really sure what an MCM is anymore. This confusion is also found in the designer’s office where the best product on the market is often determined by whoever “worked with us on the last project”. The whole while, the most important question is not what product name is chosen. The important questions are:

• Is the product/system supported by testing?

• Is there a labeling program in place (as required by code) to ensure the product being supplied to the field uses the same process, components, and quality requirements of the product that was tested?

Product labeling is more than just a name on the back of the panel. Labeling is an assurance of quality, compliance with the stated performance requirements, and conformance to the code.
