[Greenbuilding] rainscreen, siding, and yellowjackets

[Stephen]

I am going to use a rainscreen detail on my house (see my question regarding 
Manual J calcs) using cement fiberboard (not HardiBoard because they 
"insist" on the product being painted). I am deliberating using 1" or 3/4" 
air space (1" is the recommended spacing but it appears that this is for a 
max of 4 (?) stories and my house is basically one story). To provide insect 
barriers I am thinking of using recycled polyester open weave mesh material 
(sort of like 3M's magic scrub without the abrasive). This is a product used 
in the masonry trades for weep holes and cavity fillers. It would be 
oversized for the opening and held in place by friction fit with something 
like 85 - 90% open area. I comes in several colors. This use is off label 
but at least one of the manufacturers was interested in supplying it in 
special sizes.

I have samples in the office but have not yet priced the material for the 
size and quantity that I need. I am not in my office now so I cannot give 
more specific info. Look for CavClear, mortar net, etc.
