I am attaching 3″ of mineral wool with 1×4 furring strips over siding covered with WRB. Most details I’m finding use a product like Cor-A-Vent SV-5 as a bug screen but this doesn’t address the 3″ edges of the mineral wool. Can you recommend a solution that addresses the whole assembly? Is fiberglass window screen wrapped across the bottom (including the rain screen gap) durable enough for this application? What is the maximum hole size you would recommend?
