If a basement is "not considered habitable" because the ceiling above is insulated per code, yet one or more walls have been framed out with studs (either a framed daylight basement wall or other framed wall in front of the concrete wall) and these walls are insulated with fiberglass batt (either faced or unfaced), do the fiberglass insulated walls need to be covered with a thermal barrier to satisfy the code? Or, should there be different requirement for faced verses unfaced. Remember the basement is "not considered habitable". In my opinion, the IRC is not clear on this.
