Hello,
There is a warehouse/industrial type building. The building ventilation is done by exhaust fans and louvers. Typical with return air systems, PVC pipe would not be ideal (because it is not plenum ASTM E84 fire and smoke rated, unless it is fire wrapped). I am pretty sure that industrial buildings like this would not qualify as a return air system, as all air is exhaust not returned.
However, just wanted to run it by other people. Is there any concern with located PVC pipe (not plenum rated pipe), in an industrial/warehouse building like this?
Thanks
