   Add 1/2" of foam between furring. Then some use stapled in fold of screen. Done. Next.

   Here in BC, where all construction in coastal areas has to include a rain screen, builders have moved away from folding insect screen at the bottom of the cavity, as it is very susceptible to damage and very difficult to replace. Instead we use a U or L flashing made of perforated material. They are commonly available here, but you may need to get one made up where you are.
   With a 3/4" air space It might be a good idea to check with your local building inspector, as codes differ in how they require the cavity to be terminated at the top. sometimes firestops are required for a gap that deep.

   Tim,
   Most builders use insect screen. If you are worried about the durability of the insect screen, you could use this product from Cor-a-vent:
