Flammability of Foil-faced Insulation

*
I have been using some foil-faced polyiso&#;whatever (the organic stuff) foam board as radiant heat shields and also on the outside of some dormers and knee walls in a bonus room. I checked the manufacturers web site just to see what info they had available, and they warned that it should not be left exposed, that it should be covered by brick, plywood, or drywall to avoid &#;flame spread&#; problems in case of a fire.

You can find more information on our web, so please take a look.

While I am not subject to code inspections, this warning concerns me. Can any of you enlighten me on this? Rob, you&#;re a big proponent of foil-faced; has this ever come up??
