Building an insulated drywall chase around the conduit is certainly *a* option, but I was hoping for better options. Interferences in tightly packed overhead spaces make building a chase like that very difficult, and difficult to work around in the future, too. Considering the wording of NEC and the lack of real listed products at this point, it might be the only viable option, though.
There's no simple fiberglass wrap or anything like that out there that offers sufficient insulation?
