Rainscreen wall with insect screen
I've got a small project where a mid-90's wood-frame wall in the mid-Hudson Valley of NY needs a rainscreen retrofit (paint's peeling off in large pieces, fairly certain there's a bit of moisture getting behind the cedar clapboard and then being cooked in the sun).
In looking around at the various methods of preventing insects from getting in the vent channels (e.g., Coravent), I'm wondering about a different method. Why not use a rolled-over strip of standard aluminum or fiberglass insect screen? Installed like so: with the sheathing & housewrap exposed, tack a "skirt" of ~1' of screen at the drip edge, hanging down beyond drip edge. Install vertical furring, then gently roll screen up and tack again, without creasing, such that the bend will fill the vent opening when compressed by the drip edge piece (or first course of siding).
Similar process for the top openings.
