Greetings
I encountered a design that has a the shaft exhaust duct riser sharing the same fire-rated enclosure with other ducts. I know this is not allowed by code. There is no space to provide a partition. The duct will be coated with an inumescent coat. I am not sure if this will provide enough insulation and how far I have to keep all the other ducts (polyisocyanurate foam panel) away. Any suggesstions?
Much obliged for all information.
