Apparently no one liked this so I'll venture an OPINION. If one of the criteria for omitting sprinklers from a space is a non-combustible or limited combustible concealed space, and this area you've described is concealed (despite being able to see into it-transparency not being part of the definition for concealed in this context) then the question revolves around the combustibility of the plastic panels above and below. I doubt if there's a non-combustible plastic panel but there may be one that falls within the limited combustibility definition. Of course both conjectures are purely speculative.
