thermal barrier installation requirments

[Yankee]

If 1/2" gyp board is being used as the thermal barrier protecting foam plastic insulation, are the seams required to be mudded/taped or otherwise protected? Under 2603.4 IBC 2009, there are several tests for the thermal barrier to remain in place, is the treatment of the seams spoken to under any of these? If the gyp is cut around electrical boxes etc, is the foam sealant to be fire rated?

Sounds like a building code item , I would ask the building official for a ruling
