Most of the plastic framed hospital boards are backed with cardboard as a cost saving feature.  However we can also use foam-core or Masonite to back up the steel.

we are looking into options on this as of 10/06

Aluminum Framed Units -- on these we can get fire resistant Masonite  or if really needed we can use Micor as the backing but then we need to use 1/2" trim and bug 2" tray and cost is very high

The Tunnel Test ASTM E 84 whicf determines the class A b and C is where they aim a blowtorch at the center of a 2 ft piece of the material and see what happens.   The Steel surface in our MarkaSteel and also Ceramic steel boards is a very effective barrier to blow torches and therefore the nature of the backing material becomes a minor issue.

It should be noted that dry erase boards in schools 99% of the time are steel over non-rated particleboard or Masonite or plywood.

explanation on MSDS sheet on Corrugated used in Smaller Plastic framed boards
his is our response to request for MSDS sheets for corrugated products:

"By generally accepted definition, corrugated containers are considered to be "articles". Quoting Section 1910.1200, Title 29 of the Code of Federal Regulations:

Definitions: "Article" means a manufactured item: (i) which is formed to a specific shape or design during manufacture; (ii) which has end use function(s) dependent in whole or in part upon its shape or design during end use; and (iii) which does not release or otherwise result in exposure to a hazardous chemical under normal conditions in use.

Because corrugated products meet these criteria, Material Safety Data Sheets are not necessary to comply with the Hazard Communication regulations and are not provided.

*** Fire Ratings required in Buildings and areas with Full Sprinklers may be much lower
