Dead space outside or inside the building envelope
I am preparing to SPF insulate a Florida house designed with an unvented attic and metal roof. On the front of the home there is large covered porch. The question is whether to include the space (ceiling and roof) above this porch inside the building envelope or to partition it off from the main house. If partitioned off and outside the building envelope, does this dead space now require ventilation? All soffits and exterior ceilings are unvented and already installed. The architect/engineer died during the holidays and it is not clearly specified in the building plans!?!
