This is generally not a concern of hospitals.
We get asked this question once a year and we have sold over 50,000 boards to 1,000 + hospitals and schools and only  had to supply them fire rated one time.  However if you really require it and want to pay for fire rated backing on the aluminum board call for a quote!
also see Fire Resistence

We have a Dry-Con treated 1/4" plywood source call for price

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 big 2" tray and cost is very high


General info on fire ratings -- Colorado   about ASTM E 84 Tunnel test

The Tunnel Test ASTM E 84 which 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.


Based on flame spread and sprinkler systems in buildings the Class B Forbo Cork may meet spec on some specific jobs.   Sprinkler systems may lower required fire rating-Check with your fire Marshall.

MSDS Sheets

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
