Would metal lath walls essentially form a Faraday cage?

Nope, no metal lath here.  Only drywall.  Though who knows...maybe the builders 
used some sort of metallic radiant barrier on the attic side of that wall.  Due 
to the design of the house, the only way to access that 30-40sqft of attic space
is to punch through the kneewall.  I probably ought to do it anyway because
I suspect there's not much insulation back there...
