From the `12 IBC, Section 716.2 - Fire-resistance-rated glazing: "Fire-resistance-rated glazing

tested as part of a fire-resistance-rated wall assembly in accordance with ASTM E 119 or UL 263

and labeled in accordance with Section 703.5 shall be permitted in fire doors and fire window

assemblies where tested and installed in accordance with their listings and shall not otherwise be

required to comply with this section."

Never mind

There are glazing materials used and tested as a wall assembly under ASTM E 119 or UL 263 and NFPA 251, Standard Methods of Tests of Fire Endurance of Building Construction and Materials, that are not covered by Section 715. Because these materials can meet the same fire-resistance requirements of the wall, they are not required to be regulated as an opening that would require the lower level of protection that a fire protection rating provides.

As long as they at listed for the rating of the wall they are good to go

Massdriver had it in #18. Build 2 walls with a 3-hour gypsum core in between, just like separating townhouses. (Gypsum Association GA-600 Fire Resistance Design Manual Area Separation Wall #ASW 2600)
