I applied rigid form insulation to the inside surface of the existing sheetrock in a bedroom

Prior to placing the insulation, I glued heavy fabric to the front to give it an aesthetic balance with the bedroom.

My concern: Will the form board out-gas causing harm to the occupants?

Robert,
Q. "Will the form board out-gas causing harm to the occupants?"

A. Probably not, but the rigid foam is definitely a fire hazard and a code violation. Building codes require rigid foam to be protected on the interior by a so-called thermal barrier equivalent in performance to 1/2-inch drywall.

In almost all cases, the easiest material to use for this purpose is 1/2-inch drywall, so that is what you should install to cover your rigid foam.

Oh! I see your point and much appreciated. I feel compeled to remove from the one wall since my 17 year old occupies the bedroom. Thanks for the quick response.
