Rated shaft enclousers in PA
Rated shaft enclousers in PA
(OP)
I have a vertical shaft in a building that has supply and return ductwork in it. The ductwork exits the shaft runs horizontally on the floor and then enter another shaft. IBC 2000 requires the whole assembly to be rated, i.e. I have to wrap the ductwork with fire proofing. Does anyone know of a way I can get around not wrapping the ductwork or enclosing the ductwork with rated gypsum? I wanted to just install fire dampers at both shaft penetrations.
Please help.
Thanks
